WebDec 2, 2013 · Between each trophic level, there is a loss of energy (3, 6), meaning that more primary production is required to sustain higher trophic levels ().Assuming an energy transfer rate of 10%, it would require 100 kg C of primary production to produce 1 kg C of a species that has a trophic level of 3 ().This energy transfer rate can vary significantly … WebEnergy transfer between trophic levels is inefficient. Only about 10% of the net productivity of one level ends up as net productivity at the next level. Ecological pyramids are visual representations of energy flow, biomass accumulation, and number of individuals at different trophic levels. Introduction
