Chemotrophs are organisms that obtain energy through chemical process called chemosynthesis rather than by photosynthesis

Explanation;Chemotrophs are organisms that obtain energy through chemical process called chemosynthesis rather than by photosynthesis. In other words they obtain energy from the oxidation of electron donors.Chemosynthesis is the biological conversion of one or more carbon molecules and nutrients into organic matter using the oxidation of inorganic molecules such as hydrogen gas, hydrogen sulfide or methane as a source of energy, rather than sunlight, as in photosynthesis.Chemotrophs are examples of autotrophs as they make their own food from chemical compounds, other than through photosynthesis.
