First part of your question is not clear.
BIOMAGNIFICATION - increase in the substances in successive trophic levels of food chain.
OR it is increase in the level of persistant pollutants (e.g. DDT) or other substances (e.G. toxic chemicals, heavy metals) per unit weight of the organism with the rise in trophic level.
