Why are bacteria so diverse metabolically? What are some of the things they are capable of and why?

Bacteria have evolved any forms of nutrition and nearly all forms of metabolic pathways early in prokaryotic life. Early in Earths history, the physical and biological environments were constantly changing. In response to these inter alterations, bacterium and other(a) types of prokaryotes developed new metabolic capabilities. Natural selection would tenderness those with the metabolic capabilities most suitable to the changing environments, so a diversity of metabolic capabilities was produced. In turn, these new metabolic capabilities would change the environment for the next community of prokaryotes. Bacteria argon class into quartette major metabolic groups based on how they recover deoxycytidine monophosphate and brawniness from the environment. Photoautotrophs are photosynthetic organisms that affair light pushing to synthesize radical compounds from speed of light dioxide. Chemoautotrophs obtain cipher by oxidizing inorganic substances and strike carbon dio xide as a carbon source. Photoheterotrophs practice session light for energy but must obtain their carbon in organic from. Chemoheterotrphs must refine organic molecules for both energy and carbon. Diverse bacteria are able to metabolise most newtonous compounds. They perform both(prenominal) of the key stairs in the cycling of nitrogen finished ecosystems. Some chemoautotrophic bacteria convert ammonium (NH4+) to nitrite (NO2-). Other bacteria denitrify nitrite or nitrate (NO3-), a process that returns nitrogen gun (N2) to the atmosphere. In a process called nitrogen fixation, prokaryotes practice nitrogen gas (N2) directly and convert it to ammonium (NH4+). oxygen has different effects on bacterial growth. Obligate aerobes use O2 for cellular respiration and need it to grow. Facultative anaerobes can use O2 but can in addition grow without it by the process of fermentation. Obligate anaerobes die when undecided to oxygen. These can personify entirely by fermentation or by anaerobic respiration. Some of the bacte! rias metabolic capabilities are very blue-chip to us humans. For example, humans use bacteria in inquiry and technology. Since bacteria are able...
