An inverted pyramid of biomass is observed in which type of ecosystem?
Correct: B
An inverted pyramid of biomass occurs in certain aquatic ecosystems, particularly open ocean or deep water ecosystems, where the biomass of producers (phytoplankton) is very low compared to the biomass of consumers (zooplankton, small fish, and large predators). This is because phytoplankton have a very rapid turnover rate—though their total biomass is small, their productivity (rate of biomass production) is high. The pyramid of numbers is also inverted in such ecosystems, but the pyramid of energy remains upright.
