Vedclass · Answer

(C) Biological magnification (biomagnification) refers to the increase in concentration of non-biodegradable toxic substances at successive trophic levels. 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. Therefore,the concentration of the toxicant increases as we move up the food chain. Option $C$ is incorrect because toxic substances are indeed transferred to higher trophic levels,which is the core mechanism of biomagnification.

Select the incorrect option regarding biological magnification (biomagnification).
