Why Plants use carbon dioxide water and sunlight to produce what?

Plants use carbon dioxide, water, and sunlight to produce glucose and oxygen through the process of photosynthesis. In this process, chlorophyll in plant cells captures sunlight, which provides the energy needed to combine carbon dioxide from the air and water from the soil. The glucose produced serves as an energy source for the plant, while oxygen is released as a byproduct into the atmosphere. This essential process supports life on Earth by providing food and oxygen for other organisms.
