Whether or not "facilitation" here is an adjective

Hello all,

Please take a look at this sentence. I'll be thankful if you help me to understand the role of "facilitation" in this sentence"

In other cases, small population size may result in the breakdown of social structures in species that practice facilitation or cooperative behaviors relating to mating, foraging, or defense.

Is it possible to construct a phrase like: "facilitation behaviors"? if so, why it is not in the form of "facilitating behaviors"?

thank you very much.
