Which one of the following pyramid in oceanic ecosystem is inverted?

Step-by-step solution

In an oceanic ecosystem, the producers are phytoplankton, which have a very short lifespan and a high turnover rate. Their standing crop biomass at any given time is much less than the biomass of the zooplankton and fishes that feed on them. As we move to higher trophic levels, the biomass increases. Therefore, the pyramid of biomass in an oceanic ecosystem is inverted. The pyramid of energy is always upright in all ecosystems because energy is lost as heat at each trophic level.
