They don't
anaerobic bacteria such as sulfabacter are killed by oxygen
Most living things use oxygen to release energy from complex organic molecules such as glucose but some living things use sulfur or other chemicals as their prime oxidising agent and can survive in the total absence of oxygen

bzzzt. wrong question. Yeast doesn't need oxygen. Things that live near hydrothermal vents don't need oxygen. Anaerobic bacteria don't need oxygen. Plants use less oxygen than they produce.
Things that do need oxygen get their energy from mitochondria (that need ATP as stated by previous contributors).

Plants need carbon-dioxide, and produce oxygen through photosynthesis.
So, the premise of your question is false.

Oxygen is required for the manufacture of adenosine triphosphate (C10H16N5O13P3) or ATP.
No ATP, no life.
