from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun The synthesis of organic compounds by certain bacteria, especially in deep-sea hydrothermal vents, using energy obtained from the chemical oxidation of simple inorganic compounds. Chemosynthesis is thought to have been used by the first forms of life on Earth.
from The Century Dictionary.
- noun The formation of carbohydrates out of inorganic compounds by an organism in darkness or in the absence of sunlight: contrasted with *photosynthesis.

- noun (Plant Physiol.) Synthesis of organic compounds by energy derived from chemical changes or reactions.
Chemosynthesisof carbohydrates occurs in the nitrite bacteria through the oxidation of ammonia to nitrous acid, and in the nitrate bacteria through the conversion of nitrous into nitric acid.

Other autotrophs use inorganic compounds instead of sunlight to make food; process known as chemosynthesis
Rather, the organisms of these ecosystems function through "chemosynthesis".
Then again, the absence of a preferred chemosynthesis pathway that formic acid photosynthesis impress, means that the old "chicken-and-egg" paradox of "what came first, enzymes or metabolism" that it promise to resolve remains.
Is a most interesting statement! indicating exact/precise measurements of the solar wind as cold fusion chemosynthesis driver?
Lots of tube worms, clam beds sitting on barren rock but when we opened them their body had taken over by a bacteria that uses chemosynthesis, not photosynthesis.
Instead of photosynthesis, there is chemosynthesis.
Soil chemosynthesis (nitrifying, hydrogen-oxidizing, iron (Fe2+) - oxidizing, and sulfur c (S) bacteria)
With the "billions and billions" of stars and their attendant planets, surely some form of photosynthesis and/or chemosynthesis would occur out there.
However, the starting point for almost all substrates is the primary production of organic matter by plant photosynthesis or (occasionally) bacterial chemosynthesis.
These organisms derive their energy through chemosynthesis of volcanic sulfur compounds and warm water solution dripping down from above.
