Here is your answer...
━━━━━━━━━━━━━━━⤵
0xygen cycle=> The process by which oxygen released into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis.
➡ The earth's three main reservoirs are the air, water, & land.
➡ The oxygen is produced by plants via photosynthesis.
➡ 0xygen is constantly used and created by different processes on planet Earth.
➡ 0xygen cycle is the biogeochemical cycle that describes the movement of oxygen.

OXYGEN CYCLE :
☆ The percentage of oxygen in air is 21% .
__________________________________
● The cyclic process by which oxygen element is circulated continuously through the living and non-living components of Biosphere constitutes oxygen cycle.
● Human beings and animals take oxygen from atmosphere through respiration.
•The Decomposition of dead organisms also takes place in oxygen from atmosphere.
• Respiration and decay dead organisms release CO2 and water.
● The CO2 and water are used by Green plants during the process of photosynthesis.
● They give out oxygen during this process. This oxygen is again used by human beings and animals.

☆Thus oxygen cycle keeps repeating in nature.
