The correct answer is:
c. The less energy the organism requires, the more efficient the energy transfer.
Explanation:
Ecological efficiency describes the capability with which energy is transported from one trophic level to the next. It is defined by a compound of efficiencies relating to organismic resource acquisition and absorption in an ecosystem.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are utilized by organisms from the next level. Trophic level transference efficiency (LTE) measures the number of energy that is assigned between trophic levels.
