Practice identifying producers, consumers, predators, prey, and the flow of energy in simple food chains and food webs.
Read each problem carefully. Use the words producer, consumer, predator, prey, and energy when they help your answer.

A simple food chain is grass -> rabbit -> fox. Which living thing is the producer, and how do you know?
- 2
In the food chain leaves -> caterpillar -> bird, what does the caterpillar eat?

What is the main source of energy for most food chains on Earth?
- 5
A deer eats grass. A wolf eats the deer. Write this food chain in the correct order using arrows.
