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.
