Producers Create the Food

Producers can build complex food molecules that are jam-packed with energy.  Most producers are photosynthesizers, using energy from sunshine to make food in a process called photosynthesis.  Chemosynthesizers are producers that use energy from chemicals like nitrogen, sulfur and iron to make food molecules.






A series of chemical reactions that transform water and carbon dioxide into sugar (glucose) and oxygen. The initial "light" reactions are produced by solar energy. Occurs in all green plants and in some bacteria and protists.
