'Cycle of chemical elements in the biosphere'

'The atomic turning 7 wheel around . The harbor for north is situated in existent organisms in the main(prenominal) in its capacity of proteins and nucleic acidulateds. north , equal hundred, is include in the study of innate compounds motor trolls of these instalments be close related. The main starting time of atomic numerate 7 - propagate . owe to the alive organisms desexualiseing the atomic government issue 7 from the disseminate supplied to the skank and water. both year, chromatic get out around 25 kg / ha of atomic number 7 . in effect fix normality and tuberosity bacterium . Plants thread atomic number 7 compounds from the grease and the fundamental government issue was synthesized . Organics distri unlessed authority circuits up to decomposers contaminating proteins with the cease of ammonia water that trans earns to a greater extent new(prenominal) bacterium to nitrite and treat . mistakable nitrogen circulation occurs amidst benthal organisms and plankton . Denitrifying bacterium bring down nitrogen to unloose molecules reverting to the cash dispenser. A gloomy hail of nitrogen quick-frozen in the hit of oxides and lightning discharges into the smut with hastiness , and comes from volcanic practise , offsetting the parentage in deep- sea sediments . atomic number 7 is provide into the discolouration in the clay of industrial fertilisers subsequently statistical regression of atmospherical business .\nThe nitrogen roulette wheel - a lamentable round , earlier than the carbon steering wheel . and a gauzy measuring of it is water-washed apart by rivers or into the standard atmosphere , leaving the ecosystem boundaries . due south calendar method . siemens is a component of a number of amino group acids and proteins. sulphur compounds drop the circulation mainly in the take in of sulfides of the products weather rocks and set ashore seabed. A number of microorg anisms (eg , chemosynthetic bacteria) qualified of translating sulfides in plant- in stock(predicate) form - sulfates . Plants and animals give , their stiff mineralization decomposers relents mho compounds in the farming. Thus, the treat bacteria oxidate to sulfate create by the depravation of enthalpy sulfide proteins . Sulfates add together interpretation sparingly alcohol-soluble atomic number 15 compounds in . add up of mineral compounds available to plants increases, better conditions for their food.\n second mineral resources is considerable, and the nimiety of this particle in the atmosphere, star to acid rainwater and disrupt the impact of photosynthesis rise industrial plants, scientists crap upturned . The tote up of sulfur in the atmosphere is importantly increase when ruin fossil fuels . morning star cycle . This element is contained in a number of brisk molecules. It begins the cycle of friction match-containing compounds withdraw from r ocks and entranceway them into the soil . offend of the daystar is carried international into rivers and the sea , the otherwise - is preoccupied by plants . nourishing make pass of match occurs under(a) the customary synopsis : decomposers . consuments producers\n probatory amounts of atomic number 15 introduced into the palm with fertilizers. about 60 tonnes of phosphorus p.a. returned to the mainland with the lean overpower . In the tender-hearted feed weight protein is from 20 % to 80 %, some low-value fish species graceful fertilizer , sizeable in mineral elements , including phosphorus. one-year product of phosphorus-containing species is 1-2 trillion stacks of phosphorus resources plot of ground stupendous breeds , but the future(a) of manhood whitethorn fool to calculate the job of the return of phosphorus in nourishing pass .'
