Organisms which obtain energy by the oxidation of reduced inorganic compounds are called:

Chemotrophs are organisms that obtain energy by the oxidation of reduced compounds. Chemoautotrophs use inorganic energy sources and are known as chemolithoautotrophs or lithoautotrophs Related Theory Chemolithoheterotrophs are a special kind of chemotroph that use inorganic compounds as an energy source and reduced organic compounds as a carbon source. Chemotrophs use fermentation and respiration to obtain energy.
