food chains
  • the transfer of energy form one organism to another as organisms feed in a sequence.
  • producers are organisms of the first feeding level that are able to produce their own food
  • plants (terrestrial), phytoplankton (aquatic) and some bacteria are example of producers and are classed as photoautotrophes or chemoautotrophes
  • photo (light) autotrophes (producers) use sunlight energy to convert inorganic carbon dioxide and water to chemical energy - food (glucose)
  • chemo or chemical autotrophes - bacteria obtain their energy by the breakdown of chemical compounds usually along processes that follow decomposition. e.g. nitrifying bacteria that convert ammonia compunds of a decaying animal to soil nitrates
