  4. 1,2 What are decomposers? • A living thing that breaks down • dead things for food. • Fungi, mushrooms, earthworms

  5. 1,3 What is an energy pyramid? It shows that the amount of usable energy in an ecosystem is less for each higher animal in the food chain.

  6. 1,4 What is a food web? A model that shows how food chains overlap in an ecosystem.

  7. 2,1 What is a consumer? A living thing that eats other living things as food.

  8. 2,2 What is interact? To work together.

  9. 2,3 What are plants? They are at the bottom of the energy pyramid. 1

  10. 2,4 What is a predator? An animal that hunts another for food.

  11. 3,1 What is a herbivore? • eats only plants • sheep and deer

  12. 3,2 What is energy? • All living things need it to live • Producers get it from sunlight. • Consumers get it from food.

  13. 3,3 What are plant-eating animals? They are second on the energy pyramid. 2 1 1

  14. 3,4 What is prey? An animal that is hunted.

  15. 4,1 What are carnivores? • a consumer that gets food • by eating other animals • lions, owls, hawks

  16. 4,2 What is a food chain? It shows how energy moves through the environment.

  17. 4,3 What are animals that eat other animals? They are third on the energy pyramid. 3 2 1

  18. 4,4 What are trees and grass? Two things on this web that get their energy directly from the sun.

  19. 5,1 What are omnivores? • eat both plants and animals • most people, bears, turtles

  20. 5,2 What is a turtle? It would come next in the food chain.

  21. 5,3 What are animals that are not usually eaten by other animals? They are at the top on the energy pyramid. 4 3 2 1

  22. 5,4 What are the robin, and mouse? Two animals on this web that are both predator and prey.
