The source of energy for chemosynthesis is manly Methane. Photosynthesis and chemosynthesis. The source of energy that is used in chemosynthesis is the chemicals. Photosynthesis use energy of light. Chemosynthesis use energy of chemicals. Chemosynthesis is prodcuts or more carbon molecules. This is nutrients coming together as a matter. Some species of bacteria make their own food through chemosynthesis.
Chemosynthesis is the conversion chemosyynthesis carbon molecule s and nutrients into organic matter. An example of this is hydrogen sulfide chemosynthesis.
This is a process used by giant tube worms, and produces sulfur. Chemosynthesis uses chemical energy and photosynthesis uses light energy. Plants or autotrophs obtain their energy from photosynthesis or chemosynthesis. This is because they are the producers of the environment. Chemosynthesis does not require sunlight so this is done by organisms that live in deep volcanic thr underwater. The difference between the two is that chemosynthesis uses chemicals instead of light energy like photosynthesis.
Chemical compoundsChemical compounds. The difference between the two is that chemosynthesis uses chemicals for Energy instead of the light Energy, chemosynthsis sunlight, as used in photosynthesis.

Learn What Chemosynthesis Means in Science
Also to know is, what are the products of chemosynthesis? During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water). Pure sulfur and sulfur compounds are produced as by-products. However, at hydrothermal vents in the deep ocean a unique ecosystem has evolved in the absence of sunlight, and its source of energy is completely different: chemosynthesis. Chemosynthesis is the process by which certain microbes create energy by mediating chemical reactions. May 19, · B. Products are produced in a reaction. C. Reactants are present at the end. Chemistry. CH4 + 2 O2 --> CO2 + 2 H2O + heat This reaction is exothermic because more energy is released when the products bond than is required to break the bonds of the reactants. The potential energy of the products (not including the.
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. In contrast, the energy source for photosynthesis the set of reactions through which carbon dioxide and water are converted into glucose and oxygen uses energy from sunlight to power the process.
The idea that microorganisms could live on inorganic compounds was proposed by Sergei Nikolaevich Vinogradnsii Winogradsky in , based on research conducted on bacteria which appeared to live from nitrogen, iron, or sulfur.
The hypothesis was validated in when the deep sea submersible Alvin observed tube worms and other life surrounding hydrothermal vents at the Galapagos Rift. Harvard student Colleen Cavanaugh proposed and later confirmed the tube worms survived because of their relationship with chemosynthetic bacteria.
The official discovery of chemosynthesis is credited to Cavanaugh. Organisms that obtain energy by oxidation of electron donors are called chemotrophs. If the molecules are organic, the organisms are called chemoorganotrophs. If the molecules are inorganic, the organisms are terms chemolithotrophs.
In contrast, organisms that use solar energy are called phototrophs. Chemoautotrophs obtain their energy from chemical reactions and synthesize organic compounds from carbon dioxide. 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 sea vents.
The word "chemosynthesis" was originally coined by Wilhelm Pfeffer in to describe energy production by oxidation of inorganic molecules by autotrophs chemolithoautotrophy. Under the modern definition, chemosynthesis also describes energy production via chemoorganoautotrophy. 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 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.
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. The bacteria oxidize sulfur from the worm's environment to produce the nourishment the animal needs.
Using hydrogen sulfide as the energy source, the reaction for chemosynthesis is:. This is much like the reaction to produce carbohydrate via photosynthesis, except photosynthesis releases oxygen gas, while chemosynthesis yields solid sulfur.
The yellow sulfur granules are visible in the cytoplasm of bacteria that perform the reaction. Another example of chemosynthesis was discovered in when bacteria were found living in basalt below the sediment of the ocean floor. These bacteria were not associated with a hydrothermal vent.
It has been suggested the bacteria use hydrogen from the reduction of minerals in seawater bathing the rock. The bacteria could react hydrogen and carbon dioxide to produce methane. While the term "chemosynthesis" is most often applied to biological systems, it can be used more generally to describe any form of chemical synthesis brought about by random thermal motion of reactants. In contrast, mechanical manipulation of molecules to control their reaction is called "mechanosynthesis".
Both chemosynthesis and mechanosynthesis have the potential to construct complex compounds, including new molecules and organic molecules. Actively scan device characteristics for identification.
