Science Review: Unit 9 - Energy Flow in Living Systems

A food web from a forest ecosystem is shown. Which of the following organisms would have the greatest impact on the food web if it were removed? Think about each food chain!

• oak tree

• hawk

• chipmunk

• rabbit

Food provides animals with the materials and energy they need for growth, warmth, and motion. Plants get material for growth mostly from air and water, and obtain energy from sunlight.

Producers provide food to consumers because-

• Mrs. Zuniga says so...and she's the boss!

• animals cannot produce their own food

• plants can easily make food from soil and water

• many animals prefer eating plants to eating meat

The chart lists some of the organisms found in the Tundra ecosystem. Which food chain correctly identifies the flow of energy? USE THE CHART!!! Look at it CAREFULLY!!!

• berries-arctic fox- ringed seal- salmon

• polar bear- caribou- grasses- sun

• wolf- arctic hare- berries

• lichen-lemming-arctic fox- polar bear

If the habitat of the Houston Toad ceased to exist, how would this most likely affect the food web shown?

• There would be a decrease in the number of wildflowers.

• There would be an increase in the number of insects.

• There would be a decrease in the number of armadillos.

This includes all living and nonliving things in an environment.

• predator

• ecosystem

• food chain
