Answer:
Mutualism
Explanation:
Mutualism is also referred to as inter specific cooperation, a phenomenon in which two organisms from two different species co-exist in such a way that both get benefit from each other, either from their activities or from their fitness. Such behavior is commonly termed as cooperation.
Here in example, we see that saguaro cactus provides food for the white-winged dove through its large fruit. The bird eats that fruit but along with fruits it also ingests the seeds present in fruits. SO, when the bird flies to some new location, it drops the seeds there. In this way cactus can colonize new lands and spread offspring in new places while birds get their food. Both get benefit so it was a mutulalistic relationship.
