Does Bacteria help to replenish oxygen in the air?
Some bacteria take in carbon dioxide and excrete oxygen and others do the opposite. Those that do excrete oxygen still do not replenish the atmosphere's oxygen, nothing does, not even the plants. There is simply a balance. While they are alive and growing, bacteria and plants give out oxygen but eventually they die and the carbon carbon they stored while they were growing is returned to the atmosphere. Once a bacteria colony or a forest has finished growing, the waste like dead bacteria or dead leaves, is in exact balance with the oxygen they give out.
