All questions

Question 1

A model of a turtle shows food molecules (matter) inside its body. When the turtle moves, an arrow labeled energy released points to a movement symbol. The model uses different symbols for matter and energy. Which statement explains how organisms get energy from food?

  1. Any time the turtle moves, energy is released randomly and does not depend on using food.
  2. The turtle's food molecules turn into energy arrows as they leave the body, so matter becomes energy in the model.
  3. The turtle releases energy when food molecules are used in chemical reactions inside its body. (correct answer)
  4. The turtle uses energy without food because energy comes from being alive, not from matter.
Explanation: The core skill is explaining the mechanism of energy acquisition from food in organisms. Food contains stored chemical energy released through internal reactions. Models represent this with food molecules depicted inside and energy arrows pointing to movement symbols. To check, ensure the model avoids showing matter converting to energy and emphasizes release during use. A misconception is that matter turns into energy, but energy is extracted while matter is conserved or transformed. Energy from food powers activities such as crawling or swimming in turtles. This energy supports overall health and behavior in all organisms.

Question 2

A model of a mouse shows food molecules inside the mouse and energy-release arrows leaving the mouse to a heat symbol. The model distinguishes matter (food molecules) from energy (arrows/symbols). Choose the ONE supported energy explanation based on the model.

  1. The mouse gets energy because eating automatically makes energy appear, even if the food is not used.
  2. The mouse gets energy because sunlight enters its body and turns into energy arrows.
  3. The mouse gets energy from food because chemical reactions in its body release energy from food molecules. (correct answer)
  4. The mouse gets energy because energy arrows are tiny pieces of food leaving the body.
Explanation: The core skill is selecting supported explanations of energy from food based on models. Food contains stored energy that is liberated when molecules are processed internally. Models convey this by showing food matter inside and distinct energy arrows leaving for heat or motion. A checking strategy is to confirm the model differentiates matter from energy without implying creation from nothing. One misconception is that sunlight directly provides animal energy, but animals get it from food chains starting with plants. Energy released from food fuels organism activities like running or hunting in mice. This process is essential for maintaining energy flow in ecosystems.

Question 3

A model of a classroom terrarium shows a small insect with food molecules drawn inside it (matter). Arrows labeled energy released point from inside the insect to a movement symbol. The model uses different symbols for matter and energy and states that organisms get energy from food. Which claim about food and energy is incorrect, based on the model?

  1. The insect gets energy from food when food is used and energy is released.
  2. The model shows energy release using arrows and symbols that are not the same as food molecules.
  3. Because the insect is moving, it does not need food to release energy. (correct answer)
  4. Food molecules are shown inside the insect to represent stored matter that can be used.
Explanation: The core skill is pinpointing incorrect claims regarding food and energy in ecosystem models. Food contains stored energy that is released to support life functions. Models show this with internal food matter and arrows to movement, using distinct symbols. A checking strategy is to identify claims contradicting the model's separation of matter and energy or food dependency. A misconception is that movement generates energy without food, but models link energy release to food use. Energy from food powers insect activities like flying or crawling in terrariums. This highlights the interdependence of matter and energy in living systems.

Question 4

A model of a frog shows food molecules inside the frog. Arrows labeled energy released point to a jumping symbol and a heat symbol. The model states: "Organisms get energy from food." Which prediction about energy availability is supported by the model if the frog has no food available for a long time?

  1. The frog will still release the same amount of energy because energy is created from nothing when it jumps.
  2. The frog will have less energy available to release for jumping because less food can be used. (correct answer)
  3. The frog will have more energy because not eating prevents energy from leaving the body.
  4. The frog will have the same energy because food is only for growth, not for releasing energy.
Explanation: The core skill is predicting energy availability based on food access in models. Food contains stored energy that organisms release as needed for functions. Models show this through food inside and energy arrows to symbols like jumping or heat. A strategy to check is to consider if reduced food leads to less energy release, aligning with the model's principles. A misconception is that energy is created independently of food, but it relies on food usage. Energy from food enables activities like leaping in frogs, crucial for escape and feeding. Without it, organisms cannot sustain prolonged activity or survival.

Question 5

A model of a rabbit shows food molecules (dots) inside its cells. When the rabbit is active, the model shows more outward arrows labeled energy released to a heat symbol, while the dots remain drawn inside the rabbit. Which evidence in the model shows energy being released?

  1. The arrows labeled "energy released" pointing outward to the heat symbol. (correct answer)
  2. The food-molecule dots being drawn inside the rabbit, because dots are energy.
  3. The rabbit being active, because activity creates energy without needing food.
  4. The model's labels, because memorizing the labels is the same as showing energy release.
Explanation: The core skill involves recognizing how energy is released from food to support organism functions. Food contains stored energy in its molecular structure, which is unlocked when the organism breaks it down internally. Models show this release through arrows labeled 'energy released' pointing from the organism to symbols of heat or activity, while food matter stays within. A good checking strategy is to look for visual distinctions in the model between stored food molecules and outgoing energy indicators. One misconception is that activity alone generates energy without food, but energy release depends on using food molecules. Energy from food powers vital activities, allowing organisms like rabbits to run, jump, or maintain body heat. In essence, this process ensures organisms have the energy needed for survival and daily functions.

Question 6

A student uses a model of a fish: food molecules are shown inside the fish, and arrows labeled energy released point to a swimming/motion symbol. The model also shows that energy symbols are different from food molecules (matter). Which claim about food and energy is incorrect, based on the model?

  1. The fish gets energy from food when the food is used in its body.
  2. Energy is released from food during chemical reactions inside the fish.
  3. Food molecules are the same thing as energy arrows, just drawn differently. (correct answer)
  4. The model uses different symbols to show matter (food) and energy (released).
Explanation: The core skill is distinguishing between correct and incorrect claims about energy derivation from food. Food contains stored potential energy that organisms release to fuel their needs. Models demonstrate energy release by using separate symbols for food molecules inside the body and arrows for energy exiting to support actions like swimming. To verify, compare model elements to see if matter and energy are treated as distinct, with energy not equated to food. A misconception is that food molecules and energy symbols are identical, but models use different representations to show they are not the same. Released energy from food drives organism activities, such as movement and metabolism in fish. Ultimately, this energy transfer is fundamental for all living things to thrive.

Question 7

Use the model to answer the question. The model shows food molecules (circles) inside an organism. When food is used, energy is shown as starbursts labeled "energy released." The model separates matter symbols from energy symbols and states that organisms get energy from food.

Choose ONE unsupported claim based on the model.

  1. Energy is released when food molecules are used in the organism.
  2. Food molecules are matter inside the organism that can be used.
  3. The organism gets energy from food when the food is used.
  4. The model shows that the organism can use energy without any food because energy comes directly from the labels on the diagram. (correct answer)
Explanation: The core skill in middle school life science is identifying unsupported claims in models of energy from food. Food contains stored energy that requires molecules for release. Models depict this with starbursts appearing only when food is used. To check, determine if claims rely on model elements or introduce unrelated ideas. A misconception is that energy comes from diagrams alone, but it's from actual food processes. Energy from food enables activities like communication and reproduction in organisms. This energy flow is critical for the continuity of life on Earth.

Question 8

A student draws a model of an organism. In the model, circles labeled "food molecules" are inside the organism (matter). Starbursts labeled "energy released" appear when the food is used (energy). The model is meant to show that organisms get energy from food.

Which claim about the model is incorrect?

  1. Because the model shows starbursts, energy must be a physical substance that can be stored in the body like matter. (correct answer)
  2. The circles represent food molecules, which are matter inside the organism.
  3. The model uses different symbols to show that matter and energy are not the same thing.
  4. The starbursts represent energy released when food is used.
Explanation: The core skill in middle school life science is evaluating claims about models of energy from food. Food contains stored energy that is not a physical substance like matter. Models portray energy release with symbols like starbursts distinct from matter representations. A checking strategy is to assess if claims treat energy as non-material, unlike matter. One misconception is that energy is stored like matter, but it's a property released from chemical bonds. Energy from food supports activities including synthesis of molecules and environmental adaptation. In summary, this energy is key to organism function and ecological balance.

Question 9

Use the model to answer the question. In the model, circles represent food molecules (matter) inside an organism, and starbursts represent energy released when food is used.

Which evidence in the model shows energy being released (not just matter moving)?

  1. The circles are drawn inside the organism, showing the organism contains food molecules.
  2. The arrow shows food molecules moving to where they are used.
  3. The starburst symbols labeled "energy released" appear when food molecules are used in the organism. (correct answer)
  4. The model labels the circles as "food molecules," which proves the organism has energy.
Explanation: The core skill in middle school life science is recognizing how models represent energy release from food in organisms. Food contains stored energy in chemical bonds that can be accessed when needed. Models depict this by showing food molecules as circles and energy release as labeled starbursts during usage. To check, look for visual elements in the model that specifically indicate energy, separate from matter movement. A misconception is that merely having food inside means energy is present, but energy is released only when food is used. This energy from food enables activities like cellular repair and reproduction in organisms. Ultimately, energy from food is vital for powering all life processes across ecosystems.

Question 10

Use the model to answer the question. In the model, food molecules (circles) are inside the organism. When the organism uses the food, energy is shown as starbursts leaving the "food used" step. The model includes a key that circles are matter and starbursts are energy.

What happens when food is used, according to the model?

  1. Energy is released from the food during chemical reactions in the organism. (correct answer)
  2. Energy is stored in the food but never released; the organism only stores it unchanged.
  3. Energy is released randomly at any time, whether or not food is used.
  4. The organism gets energy only by breaking food into smaller pieces during digestion, not by using it in reactions.
Explanation: The core skill in middle school life science is explaining what happens when organisms use food for energy. Food contains stored energy that is unlocked through metabolic processes. Models represent this by displaying energy as starbursts emitted during the 'food used' phase. To check understanding, confirm if the model links energy release to food usage rather than random or storage-only events. A misconception is that energy is only from digestion, but it's actually released in cellular reactions like respiration. This energy powers activities such as muscle contraction and nerve signaling in organisms. In essence, energy from food drives the dynamic processes that keep organisms alive.

Question 11

Use the model to answer the question. The model shows food molecules (circles) inside an organism and starbursts labeled "energy released" when food is used. Circles represent matter, and starbursts represent energy.

Choose the ONE supported energy explanation based on the model.

  1. The organism gets energy from food only after sunlight hits the food molecules inside the body.
  2. The organism gets energy from food because chemical reactions use food molecules and release stored energy as usable energy. (correct answer)
  3. The organism gets energy because the food molecules are converted into energy and no matter remains.
  4. The organism gets energy from food because food's main purpose is to build new body parts, and energy comes from growth.
Explanation: The core skill in middle school life science is selecting supported explanations of energy from food based on models. Food contains stored chemical energy that organisms can harness. Models show energy release using distinct symbols like starbursts when food molecules are processed. A checking strategy is to evaluate if the explanation aligns with the model's separation of matter and energy. One misconception is that energy comes from growth alone, but it's released from food via reactions regardless of growth. Energy from food enables activities like breathing and thinking in organisms. Overall, this energy is fundamental to sustaining life functions in all organisms.

Question 12

A model shows a person with food molecules inside their body (matter). The model shows energy symbols leaving the body (energy) when the person rides a bike. Which claim about food and energy is incorrect based on the model?

  1. Energy symbols leaving the body show that energy is released when food is used.
  2. Food molecules inside the body represent matter that can be used to release energy.
  3. The energy symbols are actually food molecules escaping the body, so the model shows matter leaving, not energy. (correct answer)
  4. The model separates matter (food molecules) from energy (symbols), showing they are not the same thing.
Explanation: The skill being tested is identifying incorrect claims about how models represent food and energy. Food molecules contain stored chemical energy that gets released when used. Models show this by using different symbols for matter (food molecules inside) and energy (energy symbols leaving), keeping them clearly distinguished. To check your answer, look for the claim that confuses what the symbols represent in the model. A common misconception is thinking the energy symbols represent matter leaving the body rather than energy being released. Understanding that models use different representations helps explain how energy from food powers activities like bike riding.

Question 13

A model shows a frog with food molecules inside it (matter). Energy symbols are shown leaving the frog (energy) when it jumps. The model also states: "Organisms get energy from food." Which prediction about energy availability is supported if the frog has no food molecules left inside it?

  1. The frog will still release the same amount of energy because energy is created whenever it decides to jump.
  2. The frog will release less energy over time because there are fewer food molecules available to use and release energy from. (correct answer)
  3. The frog will release more energy because having no food makes energy symbols appear to replace the missing matter.
  4. The frog will release the same energy because animals get energy mainly from sunlight, not food.
Explanation: The skill being tested is predicting energy availability based on food molecule availability. Food molecules contain stored chemical energy that organisms need to function. When organisms use up their food molecules, they have less stored energy available to release, which models show by having fewer energy symbols leaving the organism. To check your answer, think about what happens when the source of stored energy (food) runs out. A common misconception is thinking organisms can create energy from nothing or get it mainly from non-food sources like sunlight (which only plants do). Without food molecules to use, organisms cannot release as much energy for jumping or other activities.

Question 14

A student uses a model of a mouse. The model shows food molecules inside the mouse (matter). It also shows energy symbols leaving the mouse (energy) when the mouse runs on a wheel. Which statement explains how organisms get energy from food using the model?

  1. The mouse can keep releasing energy without food because energy is stored unchanged in the body forever.
  2. The mouse gets energy because chemical reactions use food molecules and release energy, shown by energy symbols leaving the mouse; the food molecules are matter, not energy. (correct answer)
  3. The model is a literal picture of what energy looks like, so energy symbols are actual objects that the mouse spits out.
  4. The mouse gets energy when it eats because eating itself releases energy even before the food is used inside the body.
Explanation: The skill being tested is explaining how organisms get energy from food using model representations. Food molecules contain stored chemical energy that organisms can use. When the mouse uses food molecules through chemical reactions, energy is released, shown in models as energy symbols leaving the mouse while food molecules remain represented as matter. To check your answer, look for the explanation that correctly describes the chemical reaction process and distinguishes between matter and energy. A common misconception is thinking energy symbols in models are literal objects rather than representations. The energy released from food powers the mouse's wheel-running and all life processes.

Question 15

A student looks at the model of a lizard using food. The model shows food molecules inside the lizard (matter) and separate energy symbols leaving the lizard (energy). Which statement explains how organisms get energy from food using the model?

  1. Energy is created inside the lizard from nothing whenever it moves, even if no food molecules are used.
  2. Food molecules are energy, so when the lizard eats, energy matter enters and no energy needs to be released.
  3. When the lizard uses food molecules, chemical reactions release energy, shown by energy symbols leaving; the food molecules are matter and are not the same as energy. (correct answer)
  4. Food molecules are used only to build new body parts, and the energy symbols in the model represent extra food leaving the body.
Explanation: The skill being tested is understanding how organisms get energy from food using models that show matter and energy separately. Food contains stored chemical energy that organisms can use. When organisms use food molecules through chemical reactions, energy is released, which models show as energy symbols leaving the organism. To check your answer, look for the option that correctly explains that food molecules are matter containing stored energy, and energy is released when food is used. A common misconception is thinking that food molecules ARE energy, but they are actually matter that contains stored energy. The energy released from food powers all the activities organisms do, from moving to growing to staying warm.

Question 16

A model shows a turtle with food molecules inside it (matter). The model shows energy symbols leaving the turtle (energy) when it moves. Which statement explains how organisms get energy from food using the model?

  1. Food molecules contain stored energy, and when the turtle uses the food molecules in chemical reactions, energy is released, shown by energy symbols leaving the turtle. (correct answer)
  2. Food molecules are used only for growth, and the turtle's movement energy comes from energy already in its muscles, not from food.
  3. Energy is released only if the turtle eats at that exact moment; otherwise, food cannot be used to release energy.
  4. The model shows that energy is a kind of matter because both food molecules and energy symbols take up space inside the turtle.
Explanation: The skill being tested is explaining how organisms get energy from food using model evidence. Food molecules contain stored chemical energy that organisms can access. When the turtle uses food molecules in chemical reactions, energy is released, which models show as energy symbols leaving the turtle's body. To check your answer, look for the explanation that correctly describes both the storage and release of energy from food. A common misconception is thinking food is only for growth or that movement energy comes from somewhere other than food. The energy released from food molecules powers all of the turtle's activities, including movement.

Question 17

A simplified model of a lizard shows food molecules drawn as small circles inside its body. An arrow labeled energy released points outward to a symbol of motion/heat (zigzag lines). The food circles stay inside the lizard, while the energy symbol is shown leaving the body. Based on the model, which statement explains how organisms get energy from food?

  1. Energy is released when the lizard uses food molecules in chemical reactions inside its body. (correct answer)
  2. The lizard creates new energy from nothing when it needs to move.
  3. Food is energy, so the lizard's body just moves the food-energy around without releasing anything.
  4. Food molecules leave the lizard's body as energy arrows because matter turns directly into energy.
Explanation: The core skill is understanding how organisms obtain usable energy from the food they consume. Food contains stored chemical energy in the bonds of its molecules, which organisms can access through metabolic processes. Models typically depict this by illustrating food molecules remaining inside the organism while arrows indicate energy being released outward for use in motion or heat. To check your understanding, verify if the model shows energy release without depicting matter transforming directly into energy. A common misconception is that food itself is energy, but actually, food provides the matter from which energy is extracted via chemical reactions. This released energy from food enables organisms to perform essential activities like moving, growing, and reproducing. Overall, energy from food is crucial for powering all life processes in animals such as lizards.

Question 18

Use the model to answer the question. The model shows food molecules (circles) inside an organism. When the food is used, energy is shown as starbursts labeled "energy released." Circles are matter and starbursts are energy.

Which prediction about energy availability is supported by the model if the organism has no food molecules available to use?

  1. The organism will still release the same energy because energy can be created from nothing when needed.
  2. The organism will release less usable energy because there is less food to use and release energy from. (correct answer)
  3. The organism will release more energy because having no food forces the body to make extra energy.
  4. The organism will release the same energy because eating is the only time energy is used, not when food is used inside the body.
Explanation: The core skill in middle school life science is making predictions about energy from food using models. Food contains stored energy that depends on available molecules for release. Models illustrate this by linking starbursts to the presence and use of food circles. To check, predict outcomes based on varying food availability in the model. A misconception is that energy can be created without food, but it's derived from food breakdown. Energy from food drives activities like energy storage and waste elimination in organisms. This process ensures organisms can adapt and thrive in their environments.

Question 19

A model shows a fish with food molecules inside it (matter). The model also shows energy symbols leaving the fish (energy) when the fish swims. Which claim about food and energy is incorrect based on the model?

  1. The fish gets energy from food because energy is released when the fish uses food molecules.
  2. Food molecules are matter inside the fish, and energy is shown separately as symbols leaving the fish.
  3. The energy symbols represent energy released when food is used, not pieces of food leaving the fish.
  4. Energy is the same thing as food molecules, so the circles inside the fish are energy particles moving around. (correct answer)
Explanation: The skill being tested is identifying incorrect claims about how organisms get energy from food. Food molecules contain stored chemical energy that gets released when organisms use them. Models show this by keeping food molecules (matter) and energy symbols (energy) as separate representations to avoid confusion. To check your answer, look for the statement that incorrectly describes the relationship between food and energy. A common misconception is thinking that food molecules and energy are the same thing, when actually food is matter that contains stored energy. Understanding this distinction helps explain how energy from food powers swimming and other activities.

Question 20

A model shows a bird with food molecules inside its body (matter). When the bird flies, the model shows energy symbols leaving the bird (energy). What happens when food is used, according to the model?

  1. Food molecules are turned directly into energy symbols, so matter disappears and becomes only energy.
  2. Energy is released during chemical reactions as the bird uses food molecules, and the model keeps matter (food molecules) and energy (symbols) as different kinds of representations. (correct answer)
  3. The bird gets energy from sunlight, so the food molecules are only for making feathers and bones.
  4. Energy is released only when the bird is digesting food in its stomach, not when it is using food to fly.
Explanation: The skill being tested is understanding what happens when organisms use food for energy. Food molecules contain stored chemical energy that organisms need. When organisms use food molecules through chemical reactions, energy is released, which models show as energy symbols leaving while keeping matter and energy as different representations. To check your answer, look for the option that correctly describes both the chemical reaction process and how models represent matter versus energy. A common misconception is thinking matter turns into energy or disappears, but matter and energy are different things. The energy released from these chemical reactions powers flight and all other organism activities.
