MeSH definition : Growth of organisms using AUTOTROPHIC PROCESSES for obtaining nutrients and chemotrophic
processes for obtaining a primary energy supply. Chemotrophic processes are involved
in deriving a primary energy supply from exogenous chemical sources. Chemotrophic
autotrophs (chemoautotrophs) generally use inorganic chemicals as energy sources and
as such are called chemolithoautotrophs. Most chemoautotrophs live in hostile environments,
such as deep sea vents. They are mostly BACTERIA and ARCHAEA, and are the primary
producers for those ecosystems.;
