Question

9 - food chains and food webs: energy
learning objective: determine how energy is passed from one level to the next in a trophic pyramid.
each trophic level captures only about 10% of the level that precedes it, while the rest

a.) is lost as metabolic heat because of inefficiencies of energy
b.) is gained as metabolic heat because of efficiencies of energy
c.) involves biologically unusable energy (sugars) that is not passed on
d.) makes it more efficient to consume organisms at higher trophic levels

Explanation:

In a trophic pyramid, energy transfer is inefficient. Only about 10% of energy is passed from one trophic level to the next. The remaining 90% is lost as metabolic heat due to inefficiencies in energy - conversion processes in organisms.

Answer:

A. is lost as metabolic heat because of inefficiencies of energy
