Flashcard 1: What is a habitat, in science terms, when arguing about survival?

Answer: The natural place where an organism lives and gets what it needs. Habitats provide all resources needed for life.

Flashcard 2: What is the meaning of evidence in a scientific argument about habitat survival?

Answer: Observations or facts that support the claim. Proof from observations that backs up your claim.

Flashcard 3: Choose the best reasoning: Evidence: 'Cactus has a thick stem.' Claim: 'It survives in deserts.'

Answer: The thick stem stores water, helping it live through dry conditions. Explains how the adaptation (thick stem) enables desert survival.

Flashcard 4: Identify the missing need: A rabbit has food, water, and space but no burrow or cover. What is missing?

Answer: Shelter. Animals need protection from weather and predators.

Flashcard 5: Which option is abiotic (nonliving): A) soil B) grass C) rabbit D) fungus?

Answer: A) soil. Abiotic means nonliving parts of the environment.

Flashcard 6: What is an adaptation, as used when arguing how an organism survives in a habitat?

Answer: A body part or behavior that helps an organism survive. Special features or actions that increase chances of survival.

Flashcard 7: Which option is the best claim: A) "Frogs can survive in a dry desert" B) "Frogs need moist habitats"?

Answer: B) Frogs need moist habitats. Frogs have thin skin that loses water easily.

Flashcard 8: Which evidence best supports the claim "Cactus survive in deserts"?

Answer: Cactus store water and have thick, waxy skin. These adaptations help conserve water in dry climates.

Flashcard 9: What is an adaptation?

Answer: A body part or behavior that helps an organism survive. Adaptations increase survival chances in specific habitats.

Flashcard 10: What is a food chain, as used in arguments about habitat survival?

Answer: A sequence showing who eats whom for energy. Energy flows from one organism to another through eating.

Flashcard 11: What is reasoning in a science argument about habitat survival?

Answer: How the evidence supports the claim using science ideas. Reasoning connects evidence to claims logically.

Flashcard 12: What is the meaning of reasoning in a scientific argument about habitat survival?

Answer: An explanation of how the evidence supports the claim using science ideas. Connects evidence to claim using scientific principles.

Flashcard 13: What is an adaptation that supports habitat survival?

Answer: A body part or behavior that helps an organism survive. Adaptations increase survival chances in specific environments.

Flashcard 14: What does it mean if two animals compete in the same habitat?

Answer: They both need the same limited resource. Competition occurs when resources are scarce.

Flashcard 15: What is the difference between a physical trait and a behavior in survival arguments?

Answer: Trait is a body feature; behavior is an action the organism does. Physical traits are structures; behaviors are actions.

Flashcard 16: What are the four basic needs a habitat must provide for an animal to survive?

Answer: Food, water, shelter, and space. These are essential for any animal's survival.

Flashcard 17: What is a consumer in a habitat food chain?

Answer: An organism that gets energy by eating other organisms. Cannot make own food, so depends on eating others.

Flashcard 18: What are the four basic needs a habitat must provide for an animal to survive?

Answer: Food, water, shelter, and space. These four elements are essential for animal life.

Flashcard 19: What is a claim in a science argument about habitat survival?

Answer: A statement that answers the question. Claims are testable statements about nature.

Flashcard 20: What is camouflage in a habitat survival argument?

Answer: Colors or patterns that help an organism blend into its environment. Hiding in plain sight protects from predators or helps catch prey.

Flashcard 21: What is prey in a food relationship within a habitat?

Answer: An organism that is hunted and eaten by a predator. Must avoid predators to stay alive and reproduce.

Flashcard 22: Which statement is the best evidence of competition: A) two hawks fly B) two deer eat the same grass?

Answer: B) two deer eat the same grass. Sharing food resources shows direct competition.

Flashcard 23: Identify the missing part: Claim: 'The owl survives at night.' Evidence: 'It has large eyes.' Missing?

Answer: Reasoning. Needs to explain why large eyes help night survival.

Flashcard 24: Identify the evidence: "A polar bear has thick fur and a layer of fat." What part is evidence?

Answer: Thick fur and a layer of fat. These are observable facts supporting survival claims.

Flashcard 25: What does survival mean for an organism in a habitat?

Answer: Staying alive long enough to grow and reproduce. Survival ensures species continuation through generations.

Flashcard 26: What is a resource in a habitat?

Answer: Something an organism needs and uses to live. Resources include food, water, shelter, and space.

Flashcard 27: Identify the best claim: A cactus has a thick stem that stores water; it can survive in a desert.

Answer: A cactus can survive in a desert habitat. This states what the evidence proves about survival.

Flashcard 28: What is a predator in a food relationship within a habitat?

Answer: An organism that hunts and eats other organisms. Must catch prey to get energy for survival.

Flashcard 29: What is a physical (structural) adaptation?

Answer: A body feature that helps survival, such as fur or sharp claws. Body structures evolved to help organisms thrive in their environment.

Flashcard 30: What is mimicry in a habitat survival argument?

Answer: When an organism looks like another organism for protection. Copying dangerous species warns predators to stay away.

Flashcard 31: What is a predator?

Answer: An animal that hunts and eats other animals. Predators control prey populations in ecosystems.

Flashcard 32: What is prey?

Answer: An animal that is hunted and eaten by a predator. Prey animals have adaptations to avoid predators.

Flashcard 33: What is a producer in a habitat food chain?

Answer: An organism, usually a plant, that makes its own food. Uses sunlight to create energy, starting all food chains.

Flashcard 34: Which option best states a complete argument structure used in science: claim, evidence, and reasoning?

Answer: Claim + evidence + reasoning. These three parts create a strong scientific argument.

Flashcard 35: Identify the strongest claim: A) 'It is cute.' B) 'It survives because it has thick fur.'

Answer: B) It survives because it has thick fur. B explains survival with a specific adaptation; A is just opinion.

Flashcard 36: What is the meaning of a claim in a scientific argument about habitat survival?

Answer: A statement that answers the question or makes a conclusion. States what you believe based on observations.

Flashcard 37: Which conclusion best fits: "Many trees were cut down, and bird nests decreased"?

Answer: Birds need trees for shelter and nesting sites. Trees provide essential habitat for bird reproduction.

Flashcard 38: What is prey in a habitat survival discussion?

Answer: An animal that is hunted and eaten by a predator. Prey animals are food sources for predators.

Flashcard 39: Which conclusion best fits the evidence: "Frogs need water to lay eggs." Can frogs survive in a dry desert?

Answer: No, because they need water for reproduction. Water dependency makes desert survival impossible for frogs.

Flashcard 40: What is a claim in a habitat survival argument?

Answer: A statement that answers the question being argued. Claims state your position in the argument.

Flashcard 41: Which option is the strongest evidence for a claim about habitat survival: opinion or observation?

Answer: Observation. Facts from observations are stronger than personal opinions.

Flashcard 42: What is a predator in a habitat survival discussion?

Answer: An animal that hunts and eats other animals. Predators control prey populations in ecosystems.

Flashcard 43: What is a behavioral adaptation?

Answer: An action an organism does to survive, such as migrating or hibernating. Learned or instinctive actions that improve survival chances.

Flashcard 44: Which option is biotic (living): A) sunlight B) water C) rock D) tree?

Answer: D) tree. Biotic means living or once-living organisms.

Flashcard 45: Which claim best matches this evidence: "A pond dried up and frogs disappeared"?

Answer: Frogs need water in their habitat to survive. The evidence shows frogs depend on water availability.

Flashcard 46: What is evidence in a science argument about habitat survival?

Answer: Observations or data that support a claim. Evidence must be factual and measurable.

Flashcard 47: What is reasoning in a habitat survival argument?

Answer: A statement that links evidence to the claim using science ideas. Reasoning explains why evidence supports the claim.

Flashcard 48: Which adaptation best helps a duck survive in a pond habitat?

Answer: Webbed feet for swimming. Webbing increases surface area for efficient swimming.

Flashcard 49: Identify the missing habitat need: "A rabbit has grass to eat, a pond to drink from, and bushes to hide in."

Answer: Space. Animals need territory to find resources and reproduce.

Flashcard 50: What is camouflage, and how does it help an organism survive in its habitat?

Answer: Blending in with surroundings to avoid predators or catch prey. Matching surroundings provides protection and hunting advantage.

Flashcard 51: Which adaptation best helps a polar bear survive in the Arctic?

Answer: Thick fur and fat for warmth. Insulation prevents heat loss in cold environments.

Flashcard 52: What are the four basic needs most animals must meet in a habitat to survive?

Answer: Food, water, shelter, and space. These essentials keep organisms alive and healthy in their environment.

Flashcard 53: Which option best completes a strong argument structure: Claim, Evidence, and what third part?

Answer: Reasoning. Complete arguments need claim, evidence, and reasoning.

Flashcard 54: What is competition in a habitat, and why does it matter for survival?

Answer: Organisms fight for limited resources like food, water, or space. Limited resources force organisms to compete or die.

Flashcard 55: Which statement is evidence, not a claim: A) 'It will survive.' B) 'It has webbed feet.'

Answer: B) It has webbed feet. B describes observable features; A predicts an outcome.

Flashcard 56: Choose the best reasoning: "Webbed feet help ducks survive." What reasoning best links to swimming?

Answer: Webbed feet push more water, helping ducks swim and find food. This explains how webbed feet help survival through swimming.
