Question #4cba0

1 Answer

The living beings are affected due to disruption of oxygen cycle.

Explanation:

  1. About 20 per cent oxygen is maintained in the atmosphere by the oxygen cycle. Two main events i.e., photosynthesis and respiration of the organisms are responsible for oxygen cycle. Some non-living processes such as combustion also helps oxygen cycle.
  2. During the process of photosynthesis, oxygen is released in the atmosphere as by product from the process of ''photolysis of water''.
  3. The respiration process utilizes the atmospheric oxygen for the oxidation of carbohydrate. Some other processes such as combustion of organic matters utilize atmospheric oxygen and helps in maintaining the cycle.
  4. The unbalanced human activities have heavily damaged the natural process of this cycle. The disruption of natural of oxygen cycle has threatened the existence of life on the earth. Thank you
