Transcript of 1.05H Earth's Early Atmosphere

As the temperature kept increasing, the amount fermentation (anaerobic respiration) also increased, when the temperature was so high, the organism was put under so much stress, that it was killed.
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.
That probably would have caused the atmosphere to cool down quite a bit, with the cyanobacteria, it would have also helped because they put more oxygen into the atmosphere. The other autotrophs would have been affected because, if the temperature dropped, the air would have cooled down, and the autotrophs would have not had food from the carbon dioxide, and other inorganic materials.

1.05H Earth's Early Atmosphere
At Earth's beginning, there was little, to no oxygen, so the cells that used the anaerobic process had to learn to function without oxygen. So I would think that there was probably a lot of anaerobic respiration occurring, since no organism could survive without oxygen.
Based on the conditions of early Earth, what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer.
How is anaerobic respiration affected by changes in temperature?
