interspecies interaction

all forms of interaction between species. Long-term interactions include parasitism, in which one species lives on or in another at a cost to the host; mutualism, in which both species benefit from the interaction; and commensalism, in which the species coexist with neither cost nor benefit. Short-term interspecies interactions include predator–prey relationships and the mixed flocking of birds to feed and give alarm calls together.
