Clownfish often hide in sea anemones and are thus protected from predators. the clownfish definitely benefit from this relationship. the sea anemone doesn't seem harmed by this benefit so the relationship works out for both species. this kind of interdependence is known as commensalism mutualism parasitism benefitism

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
