 Chemotrophs are [[Prokaryotic|prokaryotic]] organisms that obtain their energy source from chemical reactions<ref>Prof. Ricardo Amils Encyclopedia of Astrobiology, 2011 pages 288-289 https://link.springer.com/referenceworkentry/10.1007%2F978-3-642-11274-4_271fckLRcited on 05/12/17</ref>. The energy is obtained from the oxidation of electron donors. These can be organic [[Organotroph|(organotrophs)]] or inoganic ([[Lithotrophs|lithotrophs]]).

chemotrophs can be divided further based on their carbon source. [[Chemoautotroph|Chemoautotroph]] or [[Chemoheterotroph|chemoheterotroph.]]

=== Chemoautotroph ===

Chemoautotrophs can synthesis their own organic molecules from CO<sub>2</sub>, using energy from the oxidation of inorganic sources e.g. hydrogen sulfide, ammonia and iron<ref>Ricardo Amils, 2014 https://link.springer.com/referenceworkentry/10.1007/978-3-642-27833-4_278-2fckLRcited on 04/12/17</ref>. Also, most chemoautotrophs are bacteria or [[Archea|archea]] which are known to be [[Extremophiles|extromophiles]]. They thrive in very extreme conditions with little sunlight or oxygen such as deep sea ocean vents and hot springs<ref>No author http://www.fossilmuseum.net/Paleobiology/Paleobiologysegues/chemotrophs/chemotrophs.htm cited on 05/12/17</ref>. These conditions are needed for [[Chemosynthesis|chemosynthesis]] to occur. this is when bacteria use sulfur containing compounds to produce organic molecules<ref>No author http://www.fossilmuseum.net/Paleobiology/Paleobiologysegues/chemotrophs/chemotrophs.htm cited on 06/12/17</ref>.

=== Chemoheterotroph ===

Chemoheterotrophs cannot synthesise their own organic molecules, therefore they must take in compounds to obtain the carbon such as [[Carbohydrates|carbohydrates]] and [[Lipids|lipids<ref>No author https://courses.lumenlearning.com/boundless-microbiology/chapter/types-of-metabolism/ cited on 06/12/17</ref>.]] They still obtain energy from the oxidation of inorganic molecules.
