Energy Pyramids & The Flow Of Energy Up The Trophic Levels

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

If only 10% of an organism's energy is available for the next trophic level, what happens with the other 90% of the energy?

• It is destroyed after it is used up.
• It is used for life processes or lost as body heat.
• It remains for the next trophic level IF the predator consumes ALL of the organism.
• It is lost completely as body heat.

What makes an energy pyramid different than a food web or chain?

• It shows energy flowing from the top of the chain and downward. 
• The tropic levels are the opposite
• It shows the amount of energy in each trophic level
• It shows specific predator/prey relationships

Why are producers found at the base of the pyramid?

• They create all of the energy and therefore have the most energy of all of the trophic levels
• There are more plants than animals. 
• They begin the flow of energy in an ecosystem.
• All of these answers are correct.

True or False: Organisms will always stay in the same trophic level. 

• True-- an organism's trophic level is permanent based on the species it is. 
• False-- the trophic level an organism belongs to is based on what it is consuming in the food chain. 

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.
