LIVING SYSTEMS (Animals) 4.5 Vocabulary Review Tara W. Moore Suffolk Public Schools Elementary Lead Science Teacher

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.

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

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.

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.)

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.

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).

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

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

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.

Food Chain

Food Chain Raccoon Grass Earthworm Mushroom Wolf Moth Bear Snake Mouse Use the following producers, consumers, and decomposers to draw a food chain. Raccoon Grass Earthworm Mushroom Wolf Moth Bear Snake Mouse

Food Web Using the same animals from your food chain create a food web. (Try to use as many of the animals as you can.)

Niches Below is a picture of a butterfly. How does its niche change throughout its life cycle? During its life cycle, an organism’s niche may change. For example, what an animal eats, what eats it, and other relationships will change.

Your Niche What is your niche in your community? What was it when you were two years old? How has your niche changed over the years? Will it continue to change? Explain.

Human Impact on Ecosystems List two positive influences humans have made on ecosystems. List two negative influences humans have made on different ecosystems.
