Answer: I think it’s is sunlight I hope this is right
Step-by-step explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.Plants use chlorophyll, usually found in their leaves, to absorb sunlight. The light energy from the sun is what fuels the reactions that transform carbon dioxide and water into glucose and oxygen. Without light, photosynthesis is impossible
