Vedclass · Answer

(A) In an aquatic ecosystem,the pyramid of biomass is typically inverted.This is because the producers (phytoplanktons) have a very short life span and a high turnover rate,meaning their standing crop biomass at any given time is small.Conversely,the consumers (zooplanktons,small fishes,and large fishes) have longer life spans and accumulate more biomass.Therefore,the biomass of fishes (consumers) far exceeds that of phytoplanktons (producers) at any given moment,making the pyramid inverted.Both the Assertion and the Reason are correct,and the Reason explains why the pyramid is inverted.

$A$: Ecological pyramid of biomass is generally inverted in the sea.
$R$: Biomass of fishes far exceeds that of phytoplanktons.
