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: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-3: -options are hydrogen (H2) and ammonia (NH3). Hydrogen and ammonia can be produced and converted into energy through processes that emit zero greenhouse gases. The production of hydrogen and ammonia is massively scalable.

Detailed explanation-4: -Three sources of CO2 is sunlight glucose (sugar) and oxygen. What type of energy does the plant use to convert CO2 and H2O into sugar? The type of energy is sunlight.
