2. Structural Adaptations
Draw a picture of an animal that has a structural adaptation. Label the structural adaptation and write how the animal uses the adaptation.

3. List two structural adaptations for the fish and tell how they allow the organism to succeed in its environment.

4. Behavioral Adaptations
Draw a picture of an animal that has a behavioral adaptation. Label the behavioral adaptation and write how the animal uses the adaptation.

5. Habitat Below is a picture of a tropical fish.
Draw a picture and write a description of its habitat. (Remember an organism’s habitat provides food, water, shelter, and space.)

6. Producers
ALL LIVING THINGS NEED ENERGY FROM FOOD. Green plants are the only living things that can make their own food. They are called producers. A food chain always begins with a producer.

7. Consumers
Animals are consumers because they eat plants or other animals to get their energy. The first consumer in a food chain is an herbivore (an animal that eats only plants).

8. Consumers
The next consumer is a carnivore (an animal that eats only other animals). A carnivore may be eaten by a larger carnivore.

9. Consumers
A food chain sometimes includes a consumer that is an omnivore (an animal that eats both plants and animals).

10. Decomposers
Decomposers are consumers that break down dead plants and animals. They return materials stored in dead plants and animals to the soil, water, and air. Then green plants use the materials to make food.

11. Food Chain

12. Food Chain Raccoon Grass Earthworm Mushroom Wolf Moth Bear Snake Mouse
