Detailed explanation-1: -The process of a buildup of certain chemical substances or toxins at the higher trophic levels of a food chain is termed Biomagnification.

Detailed explanation-2: -Biomass declines as you move up through the trophic levels. However, some types of materials, especially toxic chemicals, increase with each trophic level in the food web. These chemicals usually collect in the fat of animals.

Detailed explanation-3: -Bioaccumulation means an increase in the concentration of a chemical in a biological organism over time, compared to the chemical’s concentration in the environment. Compounds accumulate in living things any time they are taken up and stored faster than they are broken down (metabolized) or excreted.
