How much of the energy in each level of a ecological pyramid gets LOST as heat or used by the organism so that it CANNOT be passed on to the next trophic level?

True or False. In this energy pyramid, the consumers on each level only get about 10 percent of energy that the trophic level before it has stored.

• True

• False

A pyramid shape is used to show the amount of available energy at each trophic level because... 

• energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up. 

• energy increases up the food chain just like the pyramid shape gets smaller as you go up. 

• energy amounts are the same at each trophic level

What is the sun's role in the energy pyramid?

• to produce chemical energy for the ecosystem.

• to provide radiant energy for producers to convert to chemical energy. 

• to start the energy flow of the ecosystem. 

• to provide mechanical energy for producers to convert to chemical energy.

An energy pyramid represents what?

• How much sunlight is available for the ecosystem to use. 

• How much energy a particular organism needs. 

• How much energy is needed to build a pyramid. 

• The amount of energy available to the next 'feeder' in a food web.
