Nitrogen Cycle

How due north-containing substances argon made unattached to and employ by existing organisms. June 08 In the atomic number 7 cycle, plants draw a bead on up nitrate ions from the soil. They are absorbed through with(predicate) the root by active transportation and are utilize to set up proteins and other nitrogen containing compounds in plant cells. Primary consumers indeed feed on plants and the proteins in their fodder are digested to conformity amino acids. The amino acids are absorbed from the gut and strengthened up into proteins which make up the tissues of the primary consumers. The same processes extend when the primary consumer is eaten by a secondary consumer. In this way, nitrogen is passed from one trophic outlet to the next through the food web. Plants need nitrogen for amino acid, protein and nucleotide synthesis. However, they assholenot use nitrogen turgidness from the atmosphere. Nitrogen foul up in the atmosphere full terminate be made available to plants by nitrogen fixture. This term refers to a number of processes which see the conversion of nitrogen gas to nitrogen-containing substances and these processes all require a significant tote up of talent. A nitrogen molecule consists of ii atoms, and the molecules have to be sever before nitrogen fixation can take place. nonpareil of the methods of fixing nitrogen is through lightning.

During a thunderstorm, the electrical energy in lightning allows nitrogen and atomic number 8 to combination to form various oxides of nitrogen. Rain washes these compounds into the soil where they can be taken up by plants as nitrates. In the UK, the amount of nitrogen fixed by lightning is small, whereas in or ! so parts of the tropics, violent thunderstorms are common and are an important way of fixing nitrogen. An industrial process used in fixing nitrogen is the Haber process, which combines nitrogen and hydrogen to produce ammonia. The reactions take place at high temperatures and pressures and require the presence of a catalyst. A lot of the ammonia produced by the Haber process is used to make...If you want to get a full essay, order it on our website: OrderEssay.net
