Detailed explanation-1: -In a pyramid of biomass, it the total dry weight (kgm−2) primary producers is about 809. It will decrease at tertiary consumer level upto.

Detailed explanation-2: -In a biomass pyramid, producers (1st trophic level) are at the base, followed by herbivores (primary consumers) and then carnivores (secondary and tertiary consumers) at the top. The pyramid of biomass shows the flow of energy from producers to consumers.

Detailed explanation-3: -A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms.

Detailed explanation-4: -Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level. The decrease in biomass from lower to higher levels is also represented by Figure above.
