Detailed explanation-1: -Biomass refers to the mass of living organisms, including plants, animals, and microorganisms, or, from a biochemical perspective, cellulose, lignin, sugars, fats, and proteins.
Detailed explanation-2: -An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Detailed explanation-3: -When energy enters a trophic level, some of it is stored as biomass (as part of organisms’ bodies). This is the energy that’s available to the next trophic level, since only energy stored as biomass can get eaten.
Detailed explanation-4: -In fact, only about ten per cent of the biomass is transferred from each trophic level to the next. The remaining 90 per cent is used by the trophic level to complete life processes . Biomass can be lost between stages because not all of the matter eaten by an organism is digested.
