Bacteria that make food by chemosynthesis nitrifying bacteria are a type of chemosynthetic bacteria, as are the bacteria that live around vents in the bottom of the ocean. In chemosynthetic symbioses, bacteria obtain energy by oxidizing inorganic material, such as hydrogen sulfide (h 2 s) and use the energy to synthesize organic matter from carbon dioxide (co 2) the organic matter they synthesize is the primary source of nutrition for their animal host.
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.
Chemosynthesis is the oldest way for organisms to produce food in the oceans or hot lakes, chemosynthetic bacteria constitute the basis of an ecosystem, where bacteria live in the mud of the ocean floor or inside larger animals, such as snails or limpets.
Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food chemosynthesis is at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate. During chemosynthesis, bacteria use the energy derived from the chemical oxidation of inorganic compounds to produce organic molecules and water this process occurs in the absence of light the life forms that utilize this method of obtaining energy are found in places, such as soil, petroleum deposits, ice caps, lava mud, animal gut, hot springs and hydrothermal vents, among many others. Chemosynthesis occurs under anaerobic conditions in some denitrifying bacteria, which oxidize hydrogen or sulfur but often require organic matter for biosynthesis chemosynthesis has been described in some strictly anaerobic meth-anogenic bacteria according to the reaction 4h 2 + co 2 = ch 4 + 2h 2 o.
The energy source for chemosynthesis may be elemental sulfur, hydrogen sulfide, molecular hydrogen, ammonia, manganese, or iron examples of chemoautotrophs include bacteria and methanogenic archaea living in deep see vents. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (eg, hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis. As bacteria reside inside the tubeworms, these creatures get a ready supply of food with no digestive system present in these creatures, they fully depend on chemosynthetic bacteria for their nutrition the bacteria residing in the tubeworms also get a steady supply of hydrogen sulfide.
Chemosynthetic bacteria are one type of autotrophic organism, a life form that derives its nutrition from nonfood sources the other type of autotroph is the photosynthetic organism, which includes most plants and some kinds of bacteria photosynthetic organisms create nutrients using light.
Chemosynthesis has been described in some strictly anaerobic meth-anogenic bacteria according to the reaction 4h 2 + co 2 = ch 4 + 2h 2 o the biosynthesis of organic compounds in chemosynthesis is achieved by autotrophic assimilation of co 2 (calvin carbon reduction cycle) just as in photosynthesis. Chemosynthesis is the oldest way for organisms to produce food in the oceans or hot lakes, chemosynthetic bacteria constitute the basis of an ecosystem, where bacteria live in the mud of the ocean floor or inside larger animals, such as snails or limpets larger predators then eat these. In addition to bacterial and archaea, some larger organisms rely on chemosynthesis a good example is the giant tube worm which is found in great numbers surrounding deep hydrothermal vents each worm houses chemosynthetic bacteria in an organ called a trophosome.
