• Photosynthesis?is a series of chemical reactions that occurs in?producers?such as plants and algae
• Photosynthesis converts?light energy?into?chemical energy?which is then stored in the?biomass?of producers
• The light energy is used to?split strong bonds?in?water molecules?(H2O),?releasing?hydrogen?and?oxygen
• Oxygen is?released into the atmosphere?as a waste product
• Hydrogen is?combined with carbon dioxide?to produce?glucose
  • Chemical energy is stored?within the?bonds?in glucose molecules; glucose can therefore function as a?fuel?for?respiration
  • It can be said that?hydrogen is stored in glucose?molecules

Photosynthesis requires energy from light to split water molecules. The resulting hydrogen combines with carbon dioxide and is stored in glucose, which fuels respiration. Oxygen is released as a waste product.
