उत्तर
The pyramid of biomass is a graphical representation of the total amount of living matter present at each trophic level of an ecosystem. The pyramid of biomass can be both upright and inverted.
The pyramid of biomass is upright in grasslands and forest ecosystems because the amount of biomass present at the producer level is higher than at the top carnivore level.
The pyramid of biomass is inverted in a pond ecosystem as the biomass of fishes exceeds the biomass of zooplankton (upon which they feed)
