Expert Answer:

Chemotrophs are a class of organisms that obtain their energy through the oxidation of inorganic molecules, such as iron and magnesium. They may be chemoautotrophs or chemoheterotrophs.

Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium. Examples of chemoautotrophs include nitrogen fixing bacteria located in the soil, iron oxidizing bacteria located in the lava beds, and sulfur oxidizing bacteria located in deep sea thermal vents.
