• C. Water cycle
• D. Oxygen cycle

Answer 1

Answer: (D)

The assimilation of oxygen from the atmosphere to the biosphere is called as oxygen cycle. As shown in the diagram, oxygen in the atmosphere is utilized by plants and animals for respiration. It results in the formation of carbon dioxide and water. These are utilized by plants for photosynthesis, which results in the production of sugars and organic compounds and the release of oxygen back into the air. This cycle is then repeated. This is the oxygen cycle,

So, the correct answer is option D.
