Vedclass · Answer

(B) Bioaccumulation refers to the process by which chemicals,such as pesticides,accumulate in the fatty tissues of an organism over time. This occurs when the rate of intake of a substance exceeds the rate at which the organism can eliminate it. Biomagnification,on the other hand,refers to the increase in concentration of a substance as it moves up the food chain. Therefore,the deposition of pesticides in the fatty tissues of an individual organism is known as bioaccumulation.
