Explanation:
Detailed explanation-1: -Only about 10% of the energy is transferred from one trophic level to another. The rest is used for life processes of the organism and some is lost as heat.
Detailed explanation-2: -On average, only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next. This is known as “the 10 percent rule” and it limits the number of trophic levels an ecosystem can support. living organisms, and the energy contained within them.
Detailed explanation-3: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
