Solution
(i) The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds than that of phytoplanktons.
(ii) The pyramid of biomass in terrestrial ecosystems are upright because producers are more in biomass than in herbivores, herbivores are more in biomass than in carnivores.

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.
