Explain the oxygen cycle in detail.

Oxygen cycle can be understood as the circulation of oxygen in nature in a variety of forms. 

Oxygen is second most in abundance among uncombined elements in the atmosphere.

The oxygen cycle helps move oxygen through three layers namely theAtmosphere, the Biosphere, and the Lithosphere.  

21% of our air is composed of oxygen. 

Plants release oxygen into the atmosphere as a by-product during the process of photosynthesis.

Animals use oxygen during respiration and release carbon dioxide which is again used up by the plant during photosynthesis.

Final Answer Hence, this is the process of the oxygen cycle where plants release oxygen as a byproduct of respiration which is used by us and we release carbon dioxide as a byproduct of respiration to be used up by the plants.
