The figure shows a pyramid of biomass, with the highest biomass at the base (primary producers) and the lowest biomass at the top (top predators). This indicates that there is a loss of energy and biomass as it moves up the trophic levels. Typically, only 10% of the energy is transferred from one trophic level to the next, while 90% is lost as heat or through other metabolic processes. Therefore, between 80 and 90% of the energy is lost at the next highest trophic level.
