Give examples of the physical components of an ecosystems that can change populations.

For example if all the trees in an ecosystem were cut down, the squirrel population would decrease because they would be more vulnerable to predators like the hawk that eat squirrels because they can’t hide in trees anymore.

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.
