Document Summary
Organisms can be classified according to their energy and carbon sources. Organisms have two ways of harvesting energy from their environment, they can obtain energy from: the sun, chemical compounds. Chemotrophs organisms that derive their energy directly from chemical e. g. animals ingest other organisms, obtaining organic molecules such as glucose that they break down in the presence of oxygen to produce carbon dioxide and water. In this process, the energy in the chemical bonds of the organic molecule is converted to energy carried in the bonds of atp. Autotrophs (cid:894)(cid:862)self feede(cid:396)s(cid:863)(cid:895) organisms that are able to convert carbon dioxide (an inorganic form of carbon) into glucose, thus providing its own organic source of carbon. Heterotrophs organisms that obtain their carbon from organic molecules synthesized by other organisms, called preformed organic molecules. eat other organisms or molecules derived from other organisms rely on other organisms for their organic forms of carbon.
