/ˈˌfoʊdoʊˌhɛdərəˈtrɑfɪk/

Origin: Formed within English, by compounding. Etymons: photo- comb. form, heterotrophic adj.

Etymology: < photo- comb. form + heterotrophic adj., after photoautotrophic adj. Compare German Photoheterotrophie photoheterotrophy (E. G. Pringsheim 1932, in Naturwissenschaften 20 479/1).

Biology.

Of an organism or its nutrition: using light energy for biosynthesis from organic nutrients; photoorganotrophic.
