Sun-->sagebrush-->jackrabbits -->coyotes What would happen to this ecosystem if the amount of rain increased? plsss tell me

The amount of sagebrush would increase, which would lead to an increased population of jackrabbits, as sagebrush their food source. As the amount of jackrabbits increase, it gets easier for coyotes to hunt for them which in return, increases their survival rate/population.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
