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. Explore the science behind chemosynthesis: learn how organisms live in total darkness, thousands of meters below sea level. 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. Chemosynthesis: this process is used by certain bacteria, which can synthesize organic compounds from carbon dioxide and water using the energy from special methods of respiration this is an alternative to solar energy and photosynthesis, which is shown below in the picture.
Bacteria living in aphotic areas of the ocean are able to survive by chemosynthesis they use energy derived from the oxidation of inorganic chemicals, such as sulfur released from deep hydrothermal vents, to produce their food. Understanding chemosynthesis at the deep sea hydrothermal vents document overview: this is a qualitatively based hands-on activity that will have students simulating life at the deep and subsequently showing bacterial and algal succession journaling is a major portion of the assessment. 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 main difference between chemosynthesis and photosynthesis is that chemosynthesis is the process which synthesizes the organic compounds in the cell by the energy generated from chemical reactions whereas photosynthesis is the process which synthesizes organic compounds by the energy obtained from the sunlight. We all make food in different ways, and the same goes for bacteria, plants, and algae this lesson goes over the two ways by which such organisms produce food: chemosynthesis and photosynthesis. Bacteria at the vents make sugar by a process call chemosynthesis rather than light they depend on the chemicals that are released into the water by the vents bacterial use chemical energy to produce organic food molecules. Purple sulfur bacteria and other bacteria able to produce food sources through the process of chemosynthesis are able to generate yellow globules of sulfur that can also be found in their cells’ cytoplasm.
Relationship between chemosynthetic bacteria and tubeworms they do not use light, but use certain chemicals as an energy source and to make food it is this process of chemosynthesis that has led to the development of marine ecosystems below the depths of light penetration share this different types of bacteria beneficial bacteria names. Photosynthesis occurs only in green plants or in organisms which have chlorophyll while chemosynthesis occurs only in bacteria photosynthesis needs sun energy as an essential requirement while chemosynthesis does not need solar energy for the process. Chemosynthetic bacteria in deep sea vents - these use chemicals from tubeworms in order to get substances to make food in return the tubeworms feed off substances made by the bacteria nitrogen. Chemosynthesis is the process of converting carbon in the form of carbon dioxide or methane into organic molecules, without sunlight present instead, methane can be used, or hydrogen sulfide as the energy source for this reaction to proceed. 2 anaerobic chemosynthesis some bacteria can live chemosynthetically without reducing o 2 and without assimilating co 2 through the calvin cycle example: utilization of h 2 + co 2 to produce methane 4 h 2 + co 2 æch 4 + 2 h 2o the energy derived from this process is used to reduce co.

They live at the bottom in the benthic zone and they are in the bottom of the food chain they are anaerobic bacteria and make their own food from the chemicals in which the y live chemosynthesis occurs deep on the ocean floor where black smoker holes occur. Bacteria living in deep, dark areas of the ocean are able to survive by chemosynthesis they use energy derived from the oxidation of inorganic chemicals, such as sulfur from deep volcanic vents, to make their food.
An example of chemosynthetic bacteria is thermodesulfovibrio yellowstonii these bacteria are found in yellowstone lake thermal vents and are thermophilic chemosynthetic bacteria. 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. Chemosynthesis uses chemical nutrients as an energy source, unlike photosynthesis, which uses sunlight although most life on earth uses photosynthesis to obtain energy, there are groups of bacteria known as chemosynthetic autotrophs that use chemosynthesis instead.

In chemosynthesis, bacteria grow in mineral-rich water, harnessing chemical energy to make organic material chemosynthesis can sustain life in absolute darkness the most extensive ecosystem based on chemosynthesis lives around undersea hot springs at these hydrothermal vents, a chemical-rich soup bubbles out of the crust and into the bottom. Definition of chemosynthesis in the english dictionary the definition of chemosynthesis in the dictionary is the formation of organic material by certain bacteria using energy derived from simple chemical reactions. 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.
For instance, the giant tube worms have bacteria in their trophosome that can produce sugars and amino acids from carbon dioxide with hydrogen sulfide as the energy source this form of chemosynthesis results in the formation of carbohydrate as well as solid globules of sulfur. Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. What is chemosynthesis if you already know the answer to this question, you should be able to tell others more about its role and important uses for instance, concentrate on nitrifying bacteria in the soil because they provide the nitrogen necessary to plants, and this means that they are important for the entire nitrogen cycle.
