Vedclass · Answer

(A) Biomagnification refers to the increase in the concentration of a persistent toxicant (such as $DDT$ or mercury) at successive trophic levels of a food chain.This occurs because a toxic substance accumulated by an organism cannot be metabolized or excreted,and is thus passed on to the next higher trophic level in a higher concentration.As a result,the concentration of the toxicant increases as we move up the food chain.
