The oxygen cycle is a biological process which helps in maintaining the oxygen level by moving through three main spheres of the earth which are:
The oxygen cycle is interconnected with the carbon cycle.
Importance of oxygen cycle:
- It is an essential biogeochemical cycle that maintains the concentration and level of oxygen.
- Oxygen is an important element required for life, however, it can be toxic to some anaerobic bacteria.
- Oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.
