Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment. The overall equation for photosynthesis is: $6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Light Energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$. The gases involved as reactants are Carbon dioxide ($\text{CO}_2$), and the gas released as a product is Oxygen ($\text{O}_2$).

Knowing the inputs and outputs of the photosynthesis process.

Plants take in carbon dioxide from the atmosphere and water from the soil. Using light energy, they convert these into glucose (a sugar) and release oxygen into the atmosphere. This process is vital for maintaining the Earth’s atmosphere composition and providing the basis for most food chains.
