II. Multiple Choice - Refer to the following diagram to answer the questions below

______The most likely reason this diagram has only five trophic levels is that

a. pollution probably destroyed the higher levels

b. no other animal is powerful enough to kill & eat the killer whale

c. too much energy is lost at each level to permit more levels

d. killer whales serve as decomposers

______In the diagram, energy flows from

a. killer whale to algae

b. krill to cod

c. leopard seal to cod

d. krill to algae

V. Food Webs – Use the food web below to answer the questions and complete the table.

1. Idenitfy a food chain from the food web above that consists only of a producer, 1˚ consumer, and a 2˚ consumer.

______

2. Idenitfy a food chain from the food web above that consists only of a producer, 1˚ consumer, 2˚ consumer,and a 3˚consumer.

______

3. Idenitfy three herbivores shown in the diagram.

______

4. Idenitfy three carnivores shown in the diagram.

______

5. What is missing from this food web? Why is this step important? ______

______

6. Complete the table by classifying all the organisms in the food web in their correct trophic levels. Please note: Some organisms

may be listed in more than one trophic level. Not all boxes will be used.

Producers / Primary Consumers / Secondary Consumers / Tertiary Consumers
