Photosynthesis can be represented using a chemical equation. The overall balanced equation is 6CO2 + 6H2O →Sunlight C6H12O6 + 6O2Source of Carbon & Oxygen + Source of Electrons & Hydrogen + Energy that drives Photosynthesis ----> Sugar + Gas produced by splitting water. Where CO2 = carbon dioxide H2O = waterC6H12O6 = glucose O2 = oxygen.
