2. **Process of Photosynthesis**:
- During photosynthesis, plants utilize sunlight to convert carbon dioxide (CO2) from the air and water (H2O) from the soil into glucose (C6H12O6), which is a type of sugar that serves as food for the plant. The general equation for photosynthesis can be summarized as:
