do all organisms require oxygen to get energy

Expert Answer:

No. There are certain organisms who do not require oxygen for obtaining energy. Such organisms are called anaerobic organisms. eg. - yeasts.

But the amount of energy released by anaerobic respiration is far less than that released by aerobic respiration.
