6. Chemotroph - Wikipedia

   en.wikipedia.org/wiki/Chemotroph

   A chemotroph is an organism that obtains energy by the oxidation of electron donors in their environments. [1] These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which use photons. Chemotrophs can be either autotrophic or heterotrophic.
