Answer

Interspecific competition has a negative effect on both species, predation has a positive effect on the predator species and (usually) a negative effect on the prey species, and mutualism has a positive effect on both species.

Work Step by Step

In interspecific competition, two different species compete with one another for the same vital resources. This competition is detrimental to both species. In predation, one species $is$ the vital resource for the other, which uses it as a food source. This is beneficial for the predator but is generally not beneficial to the prey. In mutualism, two different species cooperate and support each other's survival. This is beneficial for both species.
