• Tertiary Consumer

• Primary Consumer

In this Food Web Pyramid Which type of consumer gets only 1% of the energy stored in plants?

• Secondary Consumers

• Primary Consumers

• Tertiary Consumers

• Producers

What is the term for each step in the transfer of energy and matter within a biological community (literally means "feeding level") ?

• homologous level

• food web

• trophic level

• food chain

The image provided is an example of a(n):

• Secondary consumer eating a primary consumer

• Primary consumer eating a secondary consumer

• Primary consumer eating a producer

• Heterotroph eating an autotroph

The amount of energy that usually transfers from one trophic level to the next...

• 10%

• 20%

• 90%

• 50%

It is said that only 10% of energy available is transmitted to the next level in an energy pyramid. Where does the other 90% go?

• Lost as heat

• Used for digestion

• Lost to growth

• Given to offspring
