Statement I : In an aquatic ecosystem, pyramid of biomass is inverted.\ Statement II : Pyramid of energy is always upright, can never be inverted.\

Professor PC Thomas Classes · Answer

(a) : In a marine aquatic ecosystem, the biomass of phytoplanktons (producers) is smaller than that of zooplanktons (primary consumers) and the biomass of zooplanktons is smaller than that of secondary consumers. This results in the inverted pyramid of biomass in an aquatic ecosystem. Pyramid of energy can never be inverted because when energy flow from a particular trophic level to the next trophic level, some energy is always lost.
