Question

Which of the following is the significance of photosynthesis?

• A. Balance of carbon dioxide and oxygen
• B. Balance of nitrogen in the environment
• C. Provides food
• D. Both A and C

Answer 1

Answer: (D)

Both A and C

In the atmosphere, plants prepare food due to photosynthesis and release oxygen and animals release carbon dioxide by respiration. Animals inhale oxygen released by plants and plants use carbon dioxide for the process of photosynthesis. Hence balance of carbon dioxide and oxygen is maintained by photosynthesis. Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose.which is stored as starch inside the plant body. Plants provide food in the form of carbohydrates(glucose and starch).

So, the correct answer is 'Both A and C'.
