The carbon dioxide and oxygen balance in the atmosphere are due to:
The carbon dioxide and oxygen balance in the atmosphere are due to:
The correct option is A Photosynthesis
The correct answer is option A
Explanation for Correct answer:
Photosynthesis:
- The process of fixing atmospheric carbon by trapping the sun's energy in the biological form in the presence of chlorophyll is called photosynthesis.
- In this process, the light energy is converted to chemical energy.
- In photosynthesis, the carbon dioxide along with water is converted to the carbohydrate molecule, Glucose, with the release of oxygen in the atmosphere in the presence of chlorophyll and sunlight.
- The carbon dioxide and oxygen balance in the atmosphere are mainly due to photosynthesis because it consumes carbon dioxide and releases oxygen into the atmosphere.
Explanation for incorrect answer:
Option B
Respiration: It is a process of intake of oxygen and release of carbon dioxide into the atmosphere. The oxygen respired by living organisms is used for the oxidation of glucose and other substrates to release carbon dioxide and water into the atmosphere.
Option C
Leaf anatomy: The internal structure of a leaf is called the leaf anatomy, which is not responsible for the balance of oxygen and carbon balance
Option D
Photorespiration: It is a chemical process that occurs in higher plants in the presence of sunlight in C3 plants, some oxygen binds to the enzyme RUBISCO which reduces the fixation of carbon dioxide and leads to the formation of phosphoglycolate, sometimes this process is also termed the wasteful process as no energy and no sugar molecules are synthesized.
The final answer is option A
