Organisms that obtain energy by oxidising reduced inorganic compounds are known as?

Chemotrophs are organisms that produce energy through the oxidation of inorganic or organic molecules. They are divided into two groups: those who use organic compounds as a source of energy and those who use inorganic compounds (such as sulphur or ammonia) as a source of energy (such as sugars or fats). Chemotrophic bacteria can be found in soil, water, deep sea hydrothermal vents, and the human gastrointestinal tract, among other places.
