GENERAL KNOWLEDGE

Detailed explanation-1: -Biomagnification is the phenomenon of progressive increase in the concentration of a xenobiotic compound as it passes through the food-chain for example; DDT is absorbed by plants and microorganisms, which may be eaten by some animals including fish.

Detailed explanation-2: -Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a food chain.

Detailed explanation-3: -Biomagnification is the process where xenobiotic substances are transferred from food to an organism resulting in higher concentrations compared with the source. It is Widely believed that this is a general phenomenon for marine food webs.

Detailed explanation-4: -Biomagnification takes place as chemicals transfer from lower trophic levels to higher trophic levels within a food web, resulting in a higher concentration in apex predators.

Detailed explanation-5: -Biomagnification is the progressive increase in concentration of harmful non-biodegradable chemical per unit weight of the organisms with the successive rise in different trophic levels in a food chain.
