Energy diagrams allow ecologists to compare patterns of energy flow through the trophic levels of different ecosystems while biomass diagrams allow them to compare the amount of material present in living organisms at different trophic levels. The energy flow and biomass diagrams for a few ecosystems are given below. Choose the correct statement(s).

Options

1. AIII B cannot be the biomass pyramid of an open ocean since a biomass pyramid cannot be inverted at any level.
2. BI B and II B are the biomass pyramids of a grassland and a forest ecosystem respectively, since most of the bi
3. CIII A could be the energy flow pyramid for an open ocean.
4. DI A could be the energy flow pyramid for a forest ecosystem, since the majority of the biomass is tied up in w
