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. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
Instead of energy being at its highest peak at the top of the tropic pyramid its actually at its lowest this is because all the energy has been eaten up on the lower steps.
