Depends. Sometimes it's a matter of sexual selection - mating dances, mating calls, size, color brightness, or fighting other animals of the species for mates.
In terms of competing for food resources, there are often strong heirarchies within groups determining who gets to eat what and when, and that's usually settled through one-on-one interactions (staredowns are common, as are physical confrontations) or seniority within a group.
Between species, it can be a matter of group action, where a group swarms a food item or rest spot, or it can be nocturnal feeding versus diurnal feeding.
Basically any way that two animals can interact, they do.

I am coming over to your house, and kicking you out because I am bigger than you. Then I will eat your food. For good measure, I will eat your dog food too.

Usually by fighting to the death.
