Vocabulary
All the living and nonliving things interacting in an area make up this.
Answer: What is an ecosystem?
I hunt and eat other animals.
What is a predator?
This model shows one path of feeding relationships.
What is a food chain?
This term describes matter moving between organisms.
What is matter flow?
A simplified representation scientists use to explain a system.
What is a model?
An organism that eats other organisms to get matter and energy.
Answer: What is a consumer?
I am hunted and eaten by another animal.
What is prey?
This model shows several connected food chains.
What is a food web?
A rabbit eats a plant. In which direction does matter move?
From the plant to the rabbit.
A lion hunts a zebra. Identify the predator and the prey.
The lion is the predator; the zebra is the prey.
An animal that eats plants but not other animals.
Answer: What is an herbivore?
I am a wolf that eats deer and rabbits. What kind of consumer am I?
What is a carnivore?
In grass → rabbit → fox, which organism receives matter directly from the grass?
What is the rabbit?
A caterpillar eats a leaf. What happens to some of the leaf's matter?
Some of the matter becomes part of the caterpillar's body.
A mouse eats seeds and insects. Is it an herbivore, carnivore, or omnivore?
What is an omnivore?
An animal that eats both plants and animals.
Answer: What is an omnivore?
A bear eats berries, insects, and fish. What kind of consumer is it?
What is an omnivore?
A student draws rabbit → grass to show that a rabbit eats grass. What is wrong with the model?
The arrow should point from the grass to the rabbit because matter moves from the food source to the organism eating it.

Grass → rabbit → fox.
A student claims that every consumer is a predator. Give evidence that disproves the claim.

Why does a food web represent feeding relationships more completely than one food chain?

A student claims that the matter in a rabbit disappears when a fox eats it. Explain why this claim is incorrect.
Matter does not disappear. Some becomes part of the fox, while some leaves its body through other processes.
A field loses most of its plants. Explain how this could affect the food web using at least three science vocabulary words.
Example: Herbivores may have less food and decrease in number. Predators may then have less prey, affecting the food web and matter flow.
