Botany - Ecosystem Question with Solution | TestHub

In aquatic ecosystem, the pyramid of biomass may be inverted. For example, biomass of zooplanktons is higher than that of phytoplanktons as life span of former is longer and the latter multiply much faster though having shorter life span. A number of generations of phytoplanktons may thus be consumed by single generation of zooplanktons. Biomass of fish may still be larger as fishes are larger in size with longer life span and a number of generations of zooplanktons can be consumed by fishes.
