1958 M. J. Pelczar & R. D. Reid Microbiology ii. vi. 51/1 Forms of life incapable of utilizing radiant energy (e.g., animal life and nongreen plants) rely upon reactions of chemical compounds to provide their energy. These are called chemotrophs.
1986 M. Kogut tr. H. G. Schlegel Gen. Microbiol. vi. 184 The term chemotroph (or chemosynthetic) indicates energy gain by oxidation-reduction reactions of nutrient substrates.
2005 C. de Duve Singularities v. 48 Phototrophs function like chemotrophs except that they have the ability, dependent on the presence of the green pigment chlorophyll, to lift electrons to a high energy level with the help of light energy.
