Nutrients. Ixabiso abantu.

Zonke izinto ehlabathini benze imijikelo, ezo zibizwa ngokuba imijikelo biogeochemical. Bekela bucala ngokuqhelekileyo ezimbini yemijikelo kumjikelo kwezondlo - zejoloji (okanye enkulu) kunye nezincinane (ebizwa nangoku zasemanzini), nto leyo ebangelwe ejikeleza lomgadi izinto phakathi microorganisms komhlaba, izityalo kunye nezilwanyana.

Umjikelo Big elide, amakhulu amawaka okanye ezigidi zeminyaka. Rocks ekuhambeni kwexesha sokudiliza aphazamise. Emva koko, la manzi sadilizwa, ukuba ezifakwe kwi emgangathweni wolwandle. Ezinye zazo kunye neetyuwa kunye eziphilayo elwandle yomntu emva ilizwe. Ngapha koko, utshintsho geotectonic kwi kwesikhoko (ezifana ukuphakamisa okanye ukuthoba amazwekazi komile) nayo isetyenziswe izinto kumhlaba. Emva kwalo mjikelo lweziqalelo biogenic ngokuphindaphindiweyo.

ejikeleza zasemanzini okanye ngomjikelo lweziqalelo biogenic - umgangatho wendalo. Amanzi, ikhabhoni, izondlo zomhlaba othatha inxaxheba kwiinkqubo ubomi mbandela eziphilayo ukwakha izityalo kunye nezilwanyana. Xa wabulala ezi zinto ziphilayo, iimveliso zabo inkunkuma usebenzisa eziphilayo elula - zizibolisi okanye iiarhente ukunciphisa ziye ibolile ibe iikhompawundi ezingaphiliyo nezinto. Kwaye kwakhona, zonke uphinda: izondlo ezisetyenziswa izityalo nje ukutya - ngoko kukho umjikelo zengqo- ekuthiwa umjikelo lweziqalelo biogenic.

izinto Biogenic - yiseti lweziqalelo yemichiza ezakha izinto eziphilayo eziyimfuneko iinkqubo zabo ubomi imichiza obuqhelekileyo. Kufuneka kuqatshelwe ukuba umxholo ongqonge umhlaba onokuphila mba ephilileyo ubalwa 100 Bln. Okulahlwayo okuyingozi. Iinguqu ezenzeka kwiingcamba eliphezulu kolu qweqwe lomhlaba, ube nefuthe eziphilayo, ngoko ukwakhiwa kwawo imichiza ugqitywa kokusingqongileyo.

Chemistry izakhi.

Xa ephilayo wafumana phantse zonke izondlo afumaneka emanzini olwandle kunye kolu qweqwe lomhlaba. Kuyinto biogenic oksijini emoyeni.

Xa eziphilayo, ioksijini ludlala indima ebonakalayo, kwakunye hydrogen, calcium, nemagnesium, ikharbon, isodiyam, nesinyithi. Phakathi kwezakhi yi-70% ioksijini, 18% carbon,-10% hydrogen. Xa phosphorus, calcium, potassium, isalfure, nitrogen kunye carbon nokungaxhotyiswa yemfuduko ngaphezu izinto eziseleyo eziqulathwe eziphilayo.

Indlela beza emzimbeni ephilileyo zahlukene. Kodwa ukwakheka kwezondlo kukuba kukho "yokufudukela biogenic-athom" (imfundiso biogeochemical) chain: umhlaba kunye namanzi, waza ke ukutya kunye nabantu - ababandakanyekayo phantse zonke izinto kule nkqubo. Ukususela medium yangaphandle, ukuba ukungena i eziphilayo ukuya ithile enoba kukancinane okanye uze unike ingqalelo eyimfuneko iiseli zebhayoloji flow iinkqubo ubomi obuqhelekileyo.

Eziphilayo abalulekileyo okanye izondlo zahlulwe macrocells kunye microcells. Imixholo ye okokuqala izinto eziphilayo phezu 0,01%, ngelixa yesibini - ngaphantsi kwe 0.001%.

Macronutrients equka inyama eziphilayo bevela ngaphandle emzimbeni womntu; ithamo ekucetyiswa yokusebenzisa yabo - ngaphezu 200 mg. Emzimbeni womntu, ngokuqhelekileyo macronutrients wadliswa ukutya. Treyisa izinto, nangona inani labo lincinane kunjalo, kufuneka i eziphilayo, njengoko inxaxheba kwiinkqubo nemvelo.

Impilo entle, kufuneka ukugcina indawo rhoqo angaphakathi umzimba umxholo ubunjani kunye ubungakanani imichiza kwinqanaba nokomzimba. Kule ndlela yobomi kufuneka babe sempilweni, kunye nokutya - yeyona ezahlukahlukeneyo yaye okunesondlo.
