In biology, carbon fixation is the reduction of inorganic carbon (carbon dioxide) to organic compounds by living organisms. The most prominent example is photosynthesis. Organisms that grow by fixing carbon are called autotrophs—plants for example. Heterotrophs, like animals, are organisms that grow using the carbon fixed by autotrophs. Fixed carbon, reduced carbon, and organic carbon all mean organic compounds.

Famous quotes containing the word organisms:
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
