An inverted pyramid of biomass can be found in which ecosystem?

Correct Answer: A. Marine

Explanation: Ecological Pyramids:- Ecological pyramids show the quantitative relationship between different trophic levels in an ecosystem which can be of three types: Pyramid of Number Pyramid of Biomass Pyramid of Energy Pyramid of Biomass :- represents the total dry weight (biomass) of organisms present at each trophic level at a particular time. Usually, biomass decreases from producers herbivores carnivores, forming an upright pyramid(Grassland and Forest Ecosystems) as producers (grasses/trees) have much greater biomass than herbivores or carnivores. In the tundra ecosystem , the pyramid of biomass is upright . Despite low overall productivity due to extreme cold and short summers, energy flow remains efficient, resulting in a low but upright biomass pyramid, unlike the inverted pyramid seen in marine ecosystems. Marine Ecosystem (Inverted Pyramid):- The phytoplankton (producers) have very low biomass at any given time, because of short life span and rapid consumption by zooplankton but they possess high productivity and fast turnover rates, means they reproduce quickly and sustain higher trophic levels efficiently.
