Vedclass · Answer

(C) Biomagnification refers to the increase in concentration of non-biodegradable substances (like $DDT$ or mercury) at successive trophic levels in a food chain.In an aquatic ecosystem, the food chain typically follows the sequence: $Phytoplankton \rightarrow Zooplankton \rightarrow Small \ fish \rightarrow Large \ fish \rightarrow Fish-eating \ birds$.Since the concentration of the toxicant increases as we move to higher trophic levels, the organism at the highest trophic level will accumulate the maximum concentration.Among the given options, fish-eating birds occupy the highest trophic level, hence they exhibit the maximum biomagnification.
