Process in which specific autotrophic organisms extract inorganic compounds from their environment and convert them into organic nutrient compounds without the use of sunlight. Also see photosynthesis [..]

1898, from chemo- + synthesis.

process by which some microbes turn carbon dioxide and water into carbohydrates using energy obtained from inorganic chemical reactions.

the chemical conversion of inorganic compounds found in an autotrophic organism's surroundings into food for it. Compare Photosynthesis.

Autotrophic synthesis of organic compounds by certain bacteria; uses energy from inorganic compounds. chemosynthetic (chemoautotrophic) bacteria

the process by which bacteria use energy from chemicals, such as hydrogen sulfide, to combine water and carbon dioxide to produce carbohydrates

The process used by bacteria and some other organisms to form nutrients from carbon dioxide or methane, using energy produced by reactions involving inorganic chemicals such as sulfur.

the process by which microbes convert inorganic compounds to carbohydrates or sugars without sunlight

(n) synthesis of carbohydrate from carbon dioxide and water; limited to certain bacteria and fungi

a biological process by which an organism uses the energy from the oxidation of inorganic substances such as ammonia, sulfur, and hydrogen to form organic compounds. Unlike photosynthesis, chemosynthe [..]

The conversion of carbon molecules into organic matter using chemicals as a source of energy instead of sunlight. For more information click here.

Primary production of organic matter, using various substances instead of light as an energy source; confined to a few groups of microorganisms

See Chemoautotrophy

is the biological conversion of nutrients and simple carbon compounds, usually carbon dioxide or methane, into organic matter using chemical energy. This is exemplified by the microbes that live off of sulfur and / or metals brought up from below the surface, whether by nature (e.g. hot springs) or humans (e.g. mine tailings). Chemosynthesis is dis [..]

Autotrophic productivity that utilizes energy released during the oxidation of certain inorganic chemicals (such as sulphides) to drive biosynthesis. Compare with photosynthesis.
