0xygen Cycle➫ The process by which oxygen released into the atmosphere by photosynthetic organisms.

♦ Oxygen is an element that is very important to living organisms.

♦ The main source of atmospheric free oxygen is photosynthesis

♦ It is created and used in different ways.

♦ The quantity of oxygen is 20.95% in the atmosphere which is maintained by oxygen cycle.

♦ The oxygen cycle is often interconnected with the carbon cycle because carbon and oxygen are often combined together in a molecule.

❱ The Lithosphere
❱ The Biosphere

➧ How 0xygen produced:-

[1] Plants create the majority of the oxygen we breathe through a process called photosynthesis.

[2] In this process plants use carbon dioxide, sunlight & water to create energy.

[3] In the process they also create oxygen which they release into the air.

➧ Importance of 0xygen:-

❱ It helps move oxygen through the three main regions of the Earth.

❱ To break down sugar to produce ATP or adenosine triphosphate.
