3.If there was a sudden drop in temperature after the evolution of the first living cells, predict how that might have affected the changes in the atmosphere and the evolution of cyanobacteria and other autotrophs. Explain your answer (5 points)

Answer 1

number two is carbon dioxide ia a greenhouse gas. that means it works like a blanket it keeps the heat from the sunlight and reflects it back to earth which leads to an increase in the global temperature.
now in the early atmosphere there was a significant higher amount of carbondioxide. earth in those days was much warmer than now. when the cyanobacteria used the carbondioxide to produce oxygen. those carbon dioxide was replaced by oxygen. so the greenhouse effect decreased which resulted in a drop of the global temperature.
