One product of photosynthesis is glucose (sugar), which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival.
Photosynthesis is a very complex process. It involves many different chemical reactions that occur in a pathway or series, that is, one chemical reaction produces what the next chemical reaction needs. A chemical equation is written below which summarizes the reactants and products of the photosynthesis pathway. The equation shows that carbon dioxide and water are used with light energy to produce glucose sugar and oxygen gas.
