Answer:

Chemoautotrophs

Explanation:

Autotrophs are groups of organisms that are capable of manufacturing their own food (organic molecules) through the fixation of carbon dioxide. There are two types of autotrophs:

  • Photoautotrophs fix carbon dioxide by using light as the energy for driving the process.
  • Chemoautotrophs fix carbon dioxide by  using energy from the oxidation of inorganic molecules such as magnesium, or sulfur.

Chemoautotrophs usually inhabit extreme environment such hot vents, deep sea, etc.
