Oxygen in the atmosphere is used for three processes, namely combustion, respiration and in formation of oxides of nitrogen. Oxygen is returned to atmosphere through only one major process that is photosynthesis
The solar energy taken by plant in use to make food we consume that food and also take oxygen that plants exhale for respirationwhen we exhale we live carbon dioxide and water vapours in atmosphere which is used by plants again to make food
this is what is called oxygen cycle
