WebApr 9, 2013 · Chemosynthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances. Chemosynthetic bacteria, unlike plants, obtain their energy from the oxidation of inorganic molecules, rather than photosynthesis. Chemosynthetic bacteria use inorganic molecules, such as ammonia, … WebThe majority of it sits underwater and thus much of it remains largely unexplored. With active tectonic spreading, the MAR is the site of frequent earthquakes. Spectacular hydrothermal vents may form where magma provides heat as it rises to the seafloor. These vents are known to support diverse chemosynthetic communities.
