Question
Nitrogen Cycle
✓
Answer
- Oxygen forms $21 \%$ of the atmosphere. It is also present in the hydrosphere and lithosphere.
- The circulation and recycling of oxygen within the biosphere is called the oxygen cycle.
- This cycle, includes both the biotic and abiotic components.
- Oxygen is continuously produced as well as used up in the atmosphere.
- Oxygen is highly reactive and it readily reacts with other elements and compounds.
- As oxygen is found in various forms like molecular oxygen $\left( O _2\right)$, water $\left( H _2 O \right)$, carbon dioxide $\left( CO _2\right)$, inorganic compounds etc, the oxygen cycle of the biosphere is extremely complex.
- Oxygen is released in the process of photosynthesis, whereas it is used up in processes like respiration, combustion, decomposition, corrosion, rusting, etc.
