Why was the transition from "purple bacteria" to "green bacteria" important for the evolution of complex organisms? Use
evidence from the video and the chart in your answer.

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.
