  • Nitrogen Cycle - 1514 Words
    The Nitrogen Cycle The element nitrogen is essential to living organisms. Nitrogen moves through the different ecosystems by the way of the nitrogen cycle. Plants and microorganisms assist nitrogen on its journey through the nitrogen cycle (Gruber and Galloway 2008, 293). In nature a limited number of bacteria species and blue-green algae have the ability to biologically fix nitrogen. These microorganisms transform nitrogen (N)2 to ammonium. Lightning has the ability to fix nitrogen. It...

  • Nitrogen Fixation - 515 Words
    The growth of all organisms depends on the availability of mineral nutrients, and none is more important than nitrogen, which is required in large amounts as an essential component of proteins, nucleic acids and other cellular constituents. There is an abundant supply of nitrogen in the earth's atmosphere - nearly 79% in the form of N2 gas. However, N2 is unavailable for use by most organisms because there is a triple bond between the two nitrogen atoms, making the molecule almost inert. In...

    The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed, or "fixed" to be used by plants. Some fixation occurs in lightning strikes, but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia, which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily...

  • Nitrogen Cycle - 509 Words
    The process of Nitrogen being released from Alanine, oxidized by soil microbes, absorbed by a root, and reduced and assimilated into aspartic acid is known as the Nitrogen Cycle. This cycle is necessary because there is a shortage of nitrogen in the soil; therefore, most of the soil nitrogen is obtained from dead organic materials such as Amino Acids. The first step in this process is nitrogen being released from the amino acid. This process is known as ammonification. Alanine is used as an...

    Nitrogen cycle Nitrogen gas is a colourless, odourless and non-toxic gas which makes up about 78 percent of the atmosphere. Nitrogen is extremely important to living material; in fact plants, animals and humans could not live without it. Sprent (1987) argued that nitrogen cycle is the most important process to living organisms after the carbon cycle. But nitrogen exists as dinitrogen (N2) in the atmosphere, which living things, particularly plants, cannot synthesize (citation) The process of...
