A chemotroph is an organism that obtains energy by the oxidation of electron donors in their environments. [1] These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which use photons. Chemotrophs can be either autotrophic or heterotrophic.
Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).
A lithoautotroph is an organism that derives energy from reactions of reduced compounds of mineral (inorganic) origin. [1] Two types of lithoautotrophs are distinguished by their energy source; photolithoautotrophs derive their energy from light, while chemolithoautotrophs (chemolithotrophs or chemoautotrophs) derive their energy from chemical reactions.

The genus Beggiatoa is diverse, with representatives occupying several habitats and niches, both in fresh and salt water. In the past, they have been confused as close relatives of Oscillatoria spp. (phylum Cyanobacteria) because they have similar morphology and motility, [8] but 5S rRNA analysis showed that members of Beggiatoa are phylogenetically distant from Cyanobacteria, and are instead ...

The body of any animal in the animal kingdom is made up of a number of chemicals.Of these, only a few biochemical products have been taken into consideration to derive evidence for evolution.
An organotroph is an organism that obtains hydrogen or electrons from organic substrates. This term is used in microbiology to classify and describe organisms based on how they obtain electrons for their respiration processes.
Hebrew cantillation, trope, trop, or te'amim is the manner of chanting ritual readings from the Hebrew Bible in synagogue services. The chants are written and notated in accordance with the special signs or marks printed in the Masoretic Text of the Bible, to complement the letters and vowel points.
