Hello! Ichrak Mesloub, I noticed your article was declined at Articles for Creation, and that can be disappointing. If you are wondering or curious about why your article submission was declined please post a question at the Articles for creation help desk. If you have any other questions about your editing experience, we'd love to help you at the Teahouse, a friendly space on Wikipedia where experienced editors lend a hand to help new editors like yourself! See you there! Onel5969 (talk) 04:53, 19 March 2015 (UTC)[reply]

Pelagic Bacteria

From Greek pelagikos or pelagos meaning the sea. Of , relating to, or living in open oceans or seas rather than waters adjacent to land or inland waters. Those bacteria are living or occurring in the upper waters of the ocean, near the surface, and they are very diverse. The pelagic zones are dominated by Gammaproteobacteria. Community composition is strongly related to the geochemical environment, particularly concentrations of major ions (K+ , Na+ , Ca2+, Mg2+, Cl -, and SO4 2-) , total nitrogen and on the organic carbon in seawater for all of their energy needs. Several recent discoveries now suggest that pelagic bacteria can depart from a strictly heterotrophic lifestyle by obtaining energy through unconventional mechanisms that are linked to the penetration of sunlight into surface waters. The dominance of Gammaproteobacteria in the pelagic zone contrasts with typical freshwater bacterial communities as well as other lakes.

The creatures on earth are divided into animals and plants, same goes for the pelagic bacteria. Some have animal cells versus plant cells. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms -- both plants and animals -- for nutrition. Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon dioxide (CO2) while heterotrophs get their reduced carbon from other organisms. Autotrophs are usually plants; they are also called "self feeders" or "primary producers". The Pelagic bacteria is divided into four groups as it will be explained in the following paragraphs.

Most of the well-recognized phototrophs are autotrophic, also known as photoautotrophs, and can fix carbon. They can be contrasted with chemotrophs that obtain their energy by the oxidation of electron donors in their environments. Photoautotrophs are capable of synthesizing their own food from inorganic substances using light as an energy source. Green plants and photosynthetic bacteria are photoautotrophs. Photoautotrophic organisms are sometimes referred to asholophytic.[1] Such organisms derive their energy for food synthesis from light and are capable of using carbon dioxide as their principal source of carbon.

Photoheterotrophs (Gk: photo = light, hetero = (an)other, troph = nourishment) are heterotrophic phototrophs—that is, they are organisms that use light for energy, but cannot use carbon dioxide as their sole carbon source. Consequently, they use organic compounds from the environment to satisfy their carbon requirements; these compounds include carbohydrates, fatty acids, and alcohols. Examples of photoheterotrophic organisms include purple non-sulfur bacteria,green non-sulfur bacteria, and heliobacteria.[1] Recent research has indicated that some aphids may be able to use light to supplement their energy supply.[2]

Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic. Chemoautotrophs (or chemotrophic autotroph), (Gr: Chemo (χημία) = chemical, auto (αὐτός) = self, troph (τροφιά) = nourishment) in addition to deriving energy from chemical reactions, synthesize all necessary organic compounds fromcarbon dioxide. Chemoautotrophs use inorganic energy sources, such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia. Most are bacteria or archaea that live in hostile environments such as deep sea ventsand are the primary producers in such ecosystems. Evolutionary scientists believe that the first organisms to inhabit Earth were chemoautotrophs that produced oxygen as a by-product and later evolved into both aerobic, heterotroph animal-like organisms and photosynthetic, plant-like organisms.

Chemoheterotrophs (or chemotrophic heterotrophs) (Gr: Chemo (χημία) = chemical, hetero (ἕτερος) = (an)other, troph (τροφιά) = nourishment) are unable to fix carbon to form their own organic compounds. Chemoheterotrophs can be chemolithoheterotrophs, utilizing inorganic energy sources such as sulfur or chemoorganoheterotrophs, utilizing organic energy sources such as carbohydrates, lipids, and proteins.

We all wondered at some point in time in our life on the source of our existence. Where do we come from? We may be getting closer to the answer if we study more in depth these bacteria.
