Trace Energy from Plants to Animals - 5th Grade Science
- What term describes an animal that eats only plants in an energy model?
- Herbivore. Herbivores are primary consumers that get energy directly from plants.
- Which direction does energy move in a food chain: from prey to predator or predator to prey?
- From prey to predator. Energy flows from the organism being eaten to the one eating it.
- What is a producer in an energy-transfer model of a food chain?
- An organism that makes its own food, usually a plant. Producers convert light energy into chemical energy through photosynthesis.
- What form of energy do plants store in the food they make?
- Chemical energy. Glucose and other organic molecules store energy from photosynthesis.
- What is the name for a consumer that eats both plants and animals?
- Omnivore. These consumers have varied diets including both plant and animal sources.
- Identify the secondary consumer in this chain: grass → rabbit → hawk.
- Hawk. Hawk eats the rabbit, making it the second-level consumer.
- What is a food chain model?
- A model showing who eats whom and how energy moves. Shows linear energy flow from producers through consumers.
- What is a consumer in an energy transfer model involving plants and animals?
- An organism that gets energy by eating other organisms. Consumers cannot make their own food and must eat to obtain energy.
- What term describes an animal that eats both plants and animals in an energy model?
- Omnivore. Omnivores can obtain energy from both plant and animal sources.

- A consumer that eats both plants and animals. Omnivores can obtain energy from both plant and animal sources.
- What is the main source of energy for most food chains that start with plants?
- The Sun. Plants capture solar energy through photosynthesis to start food chains.
- What term describes an animal that eats other animals in an energy model?
- Carnivore. Carnivores are consumers that obtain energy only from other animals.
- Identify the producer in this chain: grass → grasshopper → frog.

- Frog. Frog eats the primary consumer (grasshopper), making it secondary.
- What is the name for a consumer that eats only animals?
- Carnivore. These meat-eating consumers get energy from other animals only.
- In a food web model, what does each arrow represent?
- Energy being transferred from one organism to another. Arrows show the direction of energy flow through consumption.
- Which level has the most available energy in an energy pyramid model?
- Producers (plants). Energy decreases at each level, so the base has the most.
- What is the term for an organism that must get energy by eating other organisms?
- Consumer. Consumers cannot make their own food and depend on other organisms for energy.
- What is the original source of most energy in a food chain that starts with plants?
- The Sun. Plants capture solar energy through photosynthesis to start food chains.
- In the chain seeds → mouse → snake, which organism has energy that originally came from the Sun?
- All of them (seeds, mouse, and snake). All energy in food chains originates from the Sun.
- Which direction should arrows point in an energy transfer model: toward the eater or toward the eaten?
- Toward the eater (the organism receiving energy). Arrows show energy flow direction from food source to consumer.
- Which model correctly shows energy transfer: Sun → plant → rabbit or rabbit → plant → Sun?
- Sun → plant → rabbit. Energy flows from Sun to producers to consumers.
- What is photosynthesis in an energy-transfer model from Sun to plants?
- Plants use sunlight to make sugar (stored chemical energy). Light energy converts to chemical energy stored in glucose molecules.
- What is the term for the first consumer in a food chain that eats producers?
- Primary consumer. First-level consumers feed directly on producers in the food chain.
- Which arrow direction correctly shows energy transfer: plant → rabbit or rabbit → plant?
- plant → rabbit. Arrows point toward the organism receiving energy through consumption.
- What is the term for an organism, such as a plant, that makes its own food using sunlight?
- Producer. Producers convert light energy into chemical energy through photosynthesis.
- What is a food web model?
- A model of many connected food chains in an ecosystem. Shows complex feeding relationships and energy pathways.
- Find the organism that returns nutrients by decomposition in this model: tree → deer → wolf → fungi.
- Fungi. Fungi break down dead organisms, recycling nutrients to the ecosystem.
- Identify the primary consumer in this chain: grass → rabbit → hawk.
- Rabbit. Rabbit eats the grass, making it the first consumer.
- What is a producer in an energy transfer model involving plants and animals?
- An organism that makes its own food, usually a plant. Producers convert light energy into chemical energy through photosynthesis.
- What do decomposers do in an ecosystem energy model after plants and animals die?
- They break down dead matter and recycle nutrients. Decomposers return nutrients to soil for plants to use.
- What is the stored form of energy in food molecules that moves through a food chain?
- Chemical energy. Energy is stored in molecular bonds and transferred when organisms eat.
- Identify the primary consumer in this chain: leaves → caterpillar → bird.
- Caterpillar. Caterpillar eats the producer (leaves), making it the primary consumer.
- What is the name for a consumer that eats only plants?
- Herbivore. These plant-eating consumers get energy directly from producers.
- What is an herbivore in a plant-to-animal energy transfer model?
- A consumer that eats plants. Herbivores are primary consumers that obtain energy directly from plants.
- Which model best traces energy transfer from plants to animals: food chain or water cycle?
- Food chain. Food chains specifically show energy flow through feeding relationships.
- What do the arrows in a food chain model show: the direction of energy flow or who is bigger?
- Direction of energy flow. Arrows point from eaten to eater, showing energy transfer path.
- Identify the producer in this model: algae → small fish → large fish.
- Algae. Algae performs photosynthesis, making it the producer in this chain.
- What is the correct energy-flow direction in a food chain model?
- From food to eater (from producer to consumer). Energy flows from organisms being eaten to those doing the eating.
- What is a carnivore in an energy transfer model?
- A consumer that eats other animals. Carnivores obtain energy by consuming other consumers.
- Which organism receives energy directly from the plant in this chain: algae → fish → heron?
- Fish. Fish eats algae directly, receiving its stored energy.
- What process do plants use to capture sunlight energy and store it as chemical energy in sugar?
- Photosynthesis. Plants convert light energy into chemical energy stored in glucose molecules.
- In a food chain, what is the correct order: producer, primary consumer, secondary consumer?
- Producer → primary consumer → secondary consumer. Energy flows from plants to herbivores to carnivores.
- What is typically lost from organisms during energy transfer between trophic levels?
- Heat energy. Organisms release heat through metabolism and movement.
- Choose the correct arrow direction for energy transfer: plant and deer.
- Plant → deer. Arrow points from plant to deer showing energy transfer.
- Identify the correct energy path in this model: Sun, grass, deer, wolf.
- Sun → grass → deer → wolf. Energy flows from sun to producer to primary then secondary consumer.
- What is the term for organisms that break down dead plants and animals and recycle nutrients?

- What is a decomposer in an energy-transfer model involving dead plants and animals?
- An organism that breaks down dead matter (for example, fungi). Decomposers recycle nutrients by breaking down organic matter.
- Which model shows more connected feeding relationships: a food chain or a food web?
