Some birds look for food near cattle and other livestock. the movement of the cattle churns up the ground, making insects available to the birds. the cattle appear to be unaffected by the presence of the birds. what kind of relationship exists between the birds and the cattle? o a. parasitism o b. commensalism o c. predation o d. mutualism

I think the answer is B. Commensalism. The cows are unaffected by the birds taking advantage of their stirring up the ground, while the birds benefit. Thus, this is not parasitism, while one organism benefits while the other is harmed, or preparation, where one organism kills the other for food, or mutualism, where both organisms benefit.

The answer is B. Commensalism
