Oxygen is naturally found in the Earth's atmosphere, making up about 21% of the air we breathe. It can also be found in water molecules (H2O) and in the cells of living organisms where it plays a vital role in cellular respiration. Additionally, oxygen is produced through photosynthesis by plants and certain types of bacteria.
