Question

biomagnification information

Answer 1

Biomagnification (or bioaccumulation) refers to the ability of living organisms to accumulate certain chemicals to a concentration larger than that occurring in their inorganic, non-living environment, or in the case of animals, in the food that they eat. Organisms accumulate any chemical needed for their nutrition. The major focus of biomagnification, however, is the accumulation of certain non-essential chemicals, especially certain chlorinated hydrocarbons that are persistent in the environment. These compounds are insoluble in water, but highly soluble in fats. Because almost all fats within ecosystems occur in the living bodies of organisms, chlorinated hydrocarbons such as 4,4’-(2, 2, 2-trichloroethane-1, 1-diyl)-bis(chlorobenzene) (DDT) and polychlorinated biphenyls (PCBs) tend to selectively accumulate in organisms. This can lead to ecotoxicological problems, especially for top predators at the summit of ecological food webs, who ingest the toxic prey.

Explanation:

The accumulation and progressive increase in the concentration of non biodegradable, harmful chemicals at different trophic levels in a food chain is called bioconcentration or biomagnification.
