Un oso polar como depredador alimentándose dunha foca barbuda en Svalbard, Noruega


Depredación é, en ecoloxía e bioloxía, unha relación interespecífica na que un individuo (depredador) dunha especie mata a outro doutra especie (presa) para alimentase del.


Un mesmo individuo pode ser depredador duns organismos, e presa doutros. En caso de non ser presa de ningún organismo, falaríamos dun superdepredador.


Na relación de depredación, unha especie sae beneficiada, a especie depredadora, e outra sae prexudicada, a especie presa, pasando a enerxía deste último ao primeiro (da presa ao depredador).


Son exemplos o león e maila cebra. O primeiro sería o depredador do segundo, que sería a presa.
