Which one of the following food chain is likely to have maximum concentration of harmful chemical? a) Kingfisher, Zooplankton, Fish, Phytoplankton

Fishes eat plankton.Kingfishers eat fishes.Therefore,plankton are producers(first trophic level),fishes are primary consumers(second trophic level) and kingfishers are secondary consumers(third trophic level).Now,according to principle of biomagnification,higher trophic levels have higher accumulation of harmful chemicals,Biomagnification is the phenomenon of progressive accumulation of harmful inorganic chemicals as the trophic levels increase.Therfore,kingfisher has maximum concentration.
