An Organism That Uses Chemosynthesis-4
Nitrogen bacteria are any bacteria that use nitrogen compounds in their metabolic process.While all of these bacteria use electrons from nitrogen compounds to create organic compounds, they can have very different effects on their ecosystem depending on what compounds they use.

However, iron bacteria are not the only organisms that use metal ions as an energy source for chemosynthesis.

Other types of bacteria use arsenic, manganese, or even uranium as sources of electrons for their electron transport chains!

Nitrogen bacteria can usually be divided into three classes:1.

Nitrifying bacteria: Nitrifying bacteria grow in soils that contain ammonia.

After having its electrons passed through the electron transport chain, the chemical fuel source emerges in a different form.

Hydrogen sulfide gas, for example, is converted into solid elemental sulfur plus water.

The bacteria in that equation consumes hydrogen sulfide gas (12HS), and then produces solid, elemental sulfur as a waste product (12S).

Some bacteria that use chemosynthesis use elemental sulfur itself, or more complex sulfur compounds as fuel sources, instead of hydrogen sulfide.

The term “chemosynthesis” comes from the root words “chemo” for “chemical” and “synthesis” for “to make.” Its function is similar to that of photosynthesis, which also turns inorganic matter into organic matter – but uses the energy of sunlight, instead of chemical energy to do so.

Today chemosynthesis is used by microbes such as bacteria and archaea.

  • Photosynthesis and chemosynthesis – Sea floor – Te Ara.

    Photosynthesis is the process by which plants use the sun's energy to make sugar glucose for food. Plants absorb energy from sunlight, take in carbon dioxide.…

  • What is a chemosynthetic organism -

    A chemosynthetic organism uses sulfur or other elements as a source of energy. A chemosynthetic organism is an organism that manufactures it's own food by a process of chemosynthesis.…

  • What is Chemosynthesis? with pictures -

    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. The process occurs in many bacteria, and in another group of organisms known as archaea.…

  • What Are Chemosynthetic Bacteria? Owlcation

    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. Chemosynthetic bacteria use inorganic.…

  • Chemosynthesis Definition and Examples - ThoughtCo

    Chemosynthesis is the conversion of carbon compounds and other molecules into organic this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source.…

  • What organism uses chemosynthesis? -

    The difference between the two is that chemosynthesis uses chemicals for Energy instead of the light Energy, or sunlight, as used in photosynthesis.…

  • Chemosynthesis - Wikipedia

    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.…
