Question

1. when ants get food from plants and protect the plants from being eaten, what kind of relationship do these two species have?commensalisticharmfulparasiticmutualistic

Explanation:

A mutualistic relationship is one where both species involved benefit. Here, ants gain food from plants, and plants gain protection from being eaten by ants—both organisms receive a positive benefit. Commensalism only benefits one species, parasitism harms one species for the other's gain, and "harmful" is not a defined interspecies relationship term here.

Answer:

mutualistic
