Primary metabolism table[edit]

The following table gives some examples for each nutritional group:^[5][6][7][8]

Energy source	Electron/ H-atom donor	Carbon source	Name	Examples
Sun Light Photo-	Organic -organo-	Organic -heterotroph	Photoorganoheterotroph	Some bacteria: Rhodobacter, Heliobacterium, some green non-sulfur bacteria[9]
		Carbon dioxide -autotroph	Photoorganoautotroph
	Inorganic -litho-*	Organic -heterotroph	Photolithoheterotroph	Purple non-sulfur bacteria
		Carbon dioxide -autotroph	Photolithoautotroph	Some bacteria (cyanobacteria), some eukaryotes (eukaryotic algae, land plants). Photosynthesis.
Breaking Chemical Compounds Chemo-	Organic -organo-	Organic -heterotroph	Chemoorganoheterotroph	Predatory, parasitic, and saprophytic prokaryotes. Some eukaryotes (heterotrophic protists, fungi, animals)
		Carbon dioxide -autotroph	Chemoorganoautotroph	Some archaea (anaerobic methanotrophic archaea).[10] Chemosynthesis, synthetically autotrophic Escherichia coli bacteria[11] and Pichia pastoris yeast.[12]
	Inorganic -litho-*	Organic -heterotroph	Chemolithoheterotroph	Some bacteria (Oceanithermus profundus)[13]
		Carbon dioxide -autotroph	Chemolithoautotroph	Some bacteria (Nitrobacter), some archaea (Methanobacteria). Chemosynthesis.

Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.^[1]

The terms aerobic respiration, anaerobic respiration and fermentation (substrate-level phosphorylation) do not refer to primary nutritional groups, but simply reflect the different use of possible electron acceptors in particular organisms, such as O₂ in aerobic respiration, or nitrate (NO₃⁻), sulfate (SO₄²⁻) or fumarate in anaerobic respiration, or various metabolic intermediates in fermentation.
