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.

Question

anonymous · Answer

The early Earth did not contain oxygen. Organisms had to use anaerobic respiration to survive. AR creates oxygen so certain organisms adapted and started to use this and release carbon dioxide. So, the early Earth was mostly AR and it slowly adapted due to the increased oxygen created by anaerobic respiration.
