WebBiomass shrinks with each trophic level. That is because between 80% and 90% of an organism’s energy, or biomass, is lost as heat or waste. A predator consumes only the remaining biomass. Marine food webs are usually longer than terrestrial food webs. WebFeeding relationships are shown in food chains. Each stage is a trophic level. Biomass is a measure of the total mass of living material in each trophic level.
