NEET BIOLOGY

Detailed explanation-1: -So photosynthesis is the only process among the given option that does not produce carbon dioxide instead uses it to produce food.

Detailed explanation-2: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-3: -Photosynthesis is the process of synthesis of food by plants using carbon dioxide and water in presence of sunlight and chlorophyll. Oxygen (O2) is released during the process as a waste product. Hence, oxygen is not essential for the process of photosynthesis.

Detailed explanation-4: -Photosynthesis, burning of fossil fuel, respiration is involved in the carbon cycle, transpiration is not involved in the carbon cycle.

Detailed explanation-5: -Nuclear fission does not produce any CO2. For both nuclear and renewable generation, emissions are produced indirectly, for example during the construction of the plant.
