The image above shows the chemical reaction for photosynthesis. In this reaction, plants absorb energy from the sun, and use it - along with carbon dioxide and water - to produce sugar and oxygen. Animals (including humans) rely on both the sugar and the oxygen products for survival.
A graph showing energy changes in photosynthesis can be found below.
