What term describes a close relationship between two species where both benefit?

Explanation:
Mutualism is when two species interact in a way that each gains a fitness benefit, helping both to survive or reproduce better. For example, flowers and their pollinators rely on one another: pollinators get nectar, while flowers receive help with pollen transfer for reproduction. Other interactions show why mutualism fits this description: parasitism benefits one at the expense of the other, commensalism benefits one with the other unaffected, and predation benefits one by consuming the other. So the term for a close relationship where both benefit is mutualism.
