What is an example of input during the process of photosynthesis of a plant?

An example of input during the process of photosynthesis in a plant is carbon dioxide, which is absorbed from the air through small openings in the leaves called stomata. Additionally, sunlight serves as another crucial input, providing the energy required for the photosynthesis reaction. Water, absorbed by the roots from the soil, is also essential as it is utilized in the chemical reactions to produce glucose and oxygen.
