Chemoheterotrophs cannot fix carbon to form organic compounds.Instead, they can use inorganic energy sources, such as sulfur (chemolithoheterotrophs) or organic energy sources, such as proteins, carbohydrates, and lipids (chemoorganoheterotrophs).
Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.
In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source.
The majority of life on the planet is based in a food chain which revolves around sunlight, as plants make food via photosynthesis.
In the deep ocean, however, there is no light and thus there are no plants; so instead of sunlight being the primary form of energy, chemical energy is produced via chemosynthesis.
The word "chemosynthesis" was originally coined by Wilhelm Pfeffer in 1897 to describe energy production by oxidation of inorganic molecules by autotrophs (chemolithoautotrophy).
Under the modern definition, chemosynthesis also describes energy production via chemoorganoautotrophy.
Chemosynthesis has been detected in hydrothermal vents, isolated caves, methane clathrates, whale falls, and cold seeps.
It has been hypothesized the process may permit life below the surface of Mars and Jupiter's moon Europa. Chemosynthesis can occur in the presences of oxygen, but it is not required.
Each worm houses chemosynthetic bacteria in an organ called a trophosome.
The bacteria oxidize sulfur from the worm's environment to produce the nourishment the animal needs.
