In the context of which of the following do you sometimes find the term ‘bioaccumulation’?

Bioaccumulation refers to the accumulation of substances, particularly heavy metals and other toxins, in the tissues of an organism over time.

This process occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost by catabolism and excretion.

Bioaccumulation is commonly associated with heavy metal pollution in aquatic ecosystems, where organisms at higher trophic levels accumulate higher concentrations of pollutants.

Hence, the correct answer is (b).
