A contaminant will biomagnify if it is bioaccumulated
A contaminant will biomagnify if it is bioaccumulated every step of the [[food chain]]. This means that each step of the food chain has to excrete less of the substance than it takes in. <ref>Biology of marine birds. Schreiber, E.A. & Burger, J. (Eds). 2002.

Biomagnification is bioaccumulation through ingestion of prey items. It causes contaminant concentration to increase with increasing trophic level. Because of biomagnification low trophic level species (like phytoplancton) have a lower contaminent concentration than high trofic level species (like birds). .
