  1. Sequence of processes by which higher concentrations of a substance are attained in organisms at higher trophic levels.
  2. Result of these processes of bioconcentration and bioaccumulation by which tissue concentrations of bioaccumulated chemicals increase as the chemical passes up through two or more trophic levels.
    Note: Biomagnification occurs in a food chain as a consequence of efficient transfer of a substance from food to consumer accompanied by the lack of, or very slow, excretion or degradation of the substance.
