Bacteria perform chemosynthesis

Full Answer Bacteria perform chemosynthesis species that love in Yellowstone Lake are gammaproteobacteria. Sulfur Bacteria Sulfur bacteria are found deep in the sea.


Since the energy from the Sun cannot be utilized at such depths, the tube worm absorbs hydrogen sulfide from the vent and provides it to the bacteria. Although most of them are microbes, there are some which do not fall into the classification of archaea and bacteria It is believed that the first organisms inhabiting the Earth were chemosynthetic bacteria that produced oxygen and later evolved into animal and plant-like organisms.

Some bacteria use these compounds to create nitrites, a compound of nitrogen and oxygen. Share on Facebook Chemosynthetic bacteria are one type of autotrophic organism, a life form that derives its nutrition from nonfood sources.

Hydrothermal Vent Source Chemosynthetic Bacteria Chemosynthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances.

Extremophiles are organisms that can live in very harsh environments. They are described by the type of inorganic molecule that they use as an input for their reactions.

The Haber process is used to create commercial fertilizers in a mechanized imitation of what nitrogen-fixing bacteria do in legume roots. Extremophiles are organisms that thrive under conditions that are considered detrimental for most organisms.

Types of Chemosynthetic Bacteria

The survival of many organisms living in the ecosystems of the world depends on the ability of other organisms to convert inorganic compounds into energy that can be used by these and other organisms.

These organisms are known as phototrophs because they can make their own organic molecules using sunlight as a source of energy. Chemosynthesis, as opposed to photosynthesis, does not require sunlight and can take place under extreme conditions in the hot vents under water. Some organisms obtain their energy from the sun by the process of photosynthesis.

They combine carbon dioxide and hydrogen, which frees the oxygen that they need to live and produces methane as a byproduct.

Atmospheric nitrogen is a stable compound, so the reactions that these bacteria carry out are difficult to replicate. Cavanaugh later managed to confirm that this was indeed the method by which the worms could thrive, and is generally credited with the discovery of chemosynthesis.

Some organisms that rely on chemosynthesis to derive the energy they need include nitrifying bacteria, sulfur-oxidizing bacteria, sulfur-reducing bacteria, iron-oxidizing bacteria, halobacterium, bacillus, clostridium, and vibrio, among others. The worms absorb hydrogen sulfide and funnel it to the bacteria, which in turn produce organic molecules that the tubeworm shares.

Sulfur bacteria are also found in cold seeps in the Gulf of Mexico, where hydrogen sulfide seeps out of the sediment into the sea with no accompanying heat. The first colonies were discovered near the Galapagos Islands around deep-sea hydrothermal vents.

The bacteria capture the energy from the sulfur and produces organic compounds for both the tube worm and the bacteria.

Methanobacteria These bacteria inhabit wetlands, areas high in sewage and intestinal tracts. Larger predators then eat these. The organic molecules produced by phototrophs are used by other organisms known as heterotrophs, which derive their energy from phototrophs, that is to say, they use the energy from the sun, indirectly, by feeding on them, producing the organic compounds for their subsistence.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. An example of chemosynthetic bacteria is thermodesulfovibrio yellowstonii.

What Are Chemosynthetic Bacteria?

These bacteria are found in Yellowstone Lake thermal vents and are thermophilic chemosynthetic bacteria. Other species that love in Yellowstone Lake are gammaproteobacteria.

These live at the temperatures of 86 to 93 degrees. Mar 27,  · Best Answer: Chemosynthesis is a process certain organisms use to obtain energy for the production of food, akin to photosynthesis, but without the use of sunlight.

The energy comes from the oxidization of inorganic chemicals that the organisms find in their environment.

What Is an Example of Chemosynthetic Bacteria?

The process occurs in many bacteria Status: Resolved. 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. Chemosynthesis is a procedure certain life forms use to acquire vitality for the creation of sustenance, much the same as photosynthesis, yet without the utilization of daylight.

The vitality originates from the oxidization of inorganic chemicals. 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 (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.
