Solution

Chemoautotrophs are organisms that obtain energy by the oxidation of electron donors in their environment. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic
