NEET BIOLOGY

Detailed explanation-1: -The pyramid of biomass tells us the amount of living tissue or the total mass of organisms within each trophic level. The biogeochemical cycle involves the circular flow of matter around the biosphere. Therefore, C is the correct answer.

Detailed explanation-2: -Pyramids of biomass show the total amount of living tissue at each trophic level. A pyramid of numbers shows the relative numbers of organisms at different trophic levels.

Detailed explanation-3: -A biomass pyramid shows the efficiency of energy transfer at each trophic level. It can be upright or inverted. Marine ecosystems show inverted biomass pyramids.

Detailed explanation-4: -Biomass is the dry mass of living organisms in an area (habitat) at a particular time. A pyramid of biomass represents the mass of organisms at each trophic level . A pyramid of biomass is always shaped like a pyramid because the biomass always goes down from one trophic level to the next.

Detailed explanation-5: -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.
