The biomass of a standing crop of phytoplankton is 4 kg/m2, which supports a large standing crop of zooplankton having a biomass of 11 kg/m2. This is consumed by small fishes having a biomass of 25 kg/m2, which are then consumed by large fishes with a biomass of 37 kg/m2.
Draw an ecological pyramid indicating the biomass at each stage and also name the trophic levels. Mention whether it is an upright or inverted pyramid.
