Question

"Energy is lost with each trophic level. Where does that energy go?

A.Heat
B.Some of the energy contained in food isn't digested by the consumer that ate that food
C.Some of the energy at a given trophic level isn't consumed by the trophic level above
D.All of the above"

Answer 1

Energy is lost as heat or used for metabolic processes at each trophic level of a food chain. Only about 10% of the energy at one level is available to the next level.

Step-by-step explanation:

Energy is passed up a food chain or web from lower to higher trophic levels. However, generally only about 10 percent of the energy at one level is available to the next level. This is represented by the ecological pyramid. The other 90 percent of energy is used for metabolic processes or released as heat. Some energy may also be lost as incompletely digested food that is excreted.
