Explanation:

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen. This process requires energy, which is provided by sunlight. Sunlight is captured by chlorophyll (in plants and algae) or other pigments (in bacteria) and used to drive the chemical reactions of photosynthesis. Heat, electricity, and sound do not play a direct role in powering photosynthesis.
