Which describes an interaction in which organisms work together so that all organisms in the group benefit?

the answer is Cooperation

Explanation:

Cooperation is where organisms work together to improve the survival of the entire group. for example: Meercats have a designated watcher who watches for predators or anything that could harm the meercats, once it spots trouble, it calls out to the rest of the meercats to let them know to hide in the burrows.

the most likely outcome of fewer loon territories is that hawks would increase in proportion because the benefit of victory would be greater. hawks and loons are natural rivals of resources and victories in the game, since the lakes drying up affected the loons, the hawks would be benefited from the drought.
