Part 1
Question: A plant uses sunlight, water, and carbon dioxide to make its own food. What is the plant called?
Answer: What is a producer?
Question: A rabbit eats grass because it cannot make its own food. What kind of organism is the rabbit?
Answer: What is a consumer?
Question: A dead tree falls onto the forest floor. Which organisms help break it down?
Answer: Decomposers.
Question: Which shows a food chain correctly?
A. Owl → rabbit → grass
B. Grass → rabbit → owl
C. Rabbit → grass → owl
Answer: B. Grass → rabbit → owl
Question: A pond has fish, plants, insects, water, sunlight, and rocks all interacting. What do we call this whole community?
Answer: What is an ecosystem?
Question: You see a tree growing in a forest. It does not need to eat another animal to get its food. What role does the tree have?
Answer: What is a producer?
Question: A fox eats a rabbit to get energy. Is the fox a producer or consumer?
Answer: A consumer.
Question: Fungi grow on a dead plant and break it down. What role does the fungi have?
Answer: What is a decomposer?
Question: In this food chain, grass → rabbit → fox, which organism is the producer?
Answer: The grass.
Question: You visit a forest and see trees, rabbits, foxes, fungi, soil, water, and sunlight. Are these things part of the same ecosystem?
Answer: Yes, they interact with each other and their environment.
Question: An algae gets sunlight and uses it to make its own food. Why is algae a producer?
Answer: Because it makes its own food.
Question: You see a rabbit eating a plant and a fox eating the rabbit. Which two organisms are consumers?
Answer: The rabbit and fox.
Question: Why are decomposers sometimes called the ecosystem's "cleanup crew"?
Answer: Because they break down dead plants and animals.
Question: In the chain grass → rabbit → owl, what does the rabbit get from eating grass?
Answer: Energy.
Question: A rabbit eats plants, a fox eats the rabbit, and fungi break down dead organisms. What does this show about an ecosystem?
Answer: Organisms depend on and interact with one another.
Question: A forest loses most of its plants. What would happen to animals that depend on plants for food?
Answer: They would have less food and energy.
Question: A fox cannot find any animals or plants to eat. What problem will the fox have?
Answer: It will have trouble getting energy/food.
Question: Imagine there were no decomposers in a forest. What would happen to dead plants and animals?
Answer: They would build up because nothing would break them down.
Question: Put these organisms in the correct food-chain order:
owl, fungi, eucalyptus tree, koala
Answer: Eucalyptus tree → koala → owl → fungi.
Question: A forest has plenty of plants, animals, and decomposers working together. Why is each group important?
Answer: They each have an important role in keeping the ecosystem balanced.
Question: A rabbit eats grass, but the grass gets its energy from sunlight. Which organism starts this flow of energy?
Answer: The grass, a producer.
Question: A rabbit eats a plant, and then an owl eats the rabbit. Which animal is the secondary consumer?
Answer: The owl.
Question: A dead animal is broken down by fungi, and nutrients return to the soil. What important job did the fungi perform?
Answer: It decomposed the dead animal and recycled nutrients into the soil.
Question: A food chain shows how energy moves through organisms. If the plant at the beginning disappears, what will most likely happen to the animals later in the chain?
Answer: They will have less food and energy.
Question: Imagine one group of organisms suddenly disappears from an ecosystem. Why could this affect many other organisms?
Answer: Because organisms are connected through food chains and energy flow.
