Explanation:

In bioaccumulation there is an increase in concentration of a pollutant from the environment in the first organism in a food chain.
Bioaccumulation is the accumulation of substances, such as pesticides, or other chemicals in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost by catabolism and excretion.
