Zonke izinto eziphilayo zidinga umsoco namaminerali ukuze ziphile. Uhlobo ngalunye lunezindlela zalo zokufeza lokhu futhi, yize izitshalo zingenazandla noma imilomo, zisungule necebo elisebenzayo lokukhula. Kepha, okusho ukuthi?
Impela kuyakumangaza ngendlela izitshalo zimunca kanjani izakhamzimba.
Futhi konke kuqala lapha, ngezimpande. Imvamisa zizohlala zingaphansi komhlaba, kepha kunezinhlobo ezithile zezinhlobo zezimpande zazo ezingabonakala, okungenani kancane, zikhula ngaphezu komhlaba, njengoba kunjalo ngoFicus ngokwesibonelo. Izimpande, njengoba imbewu ihluma, zinezinhloso ezimbili kuphela: ukubamba isitshalo phansi futhi ukumunca umswakama ukwethula kuwo. Bakwenza kahle kangangoba kunezinhlobo zezinto eziphilayo okufanele zitshalwe ebangeni eliphephile kusuka emapayipini, emachibini, nakweminye imithombo yamanzi.
Konke abakumunzayo emhlabeni (amanzi namaminerali atholakala kuwo) kwaziwa ngegama lempuphu eluhlaza, ehanjiswa emaqabungeni. Uma sesifikile lapho, futhi ngenxa yesikhutha kanye namandla avela elangeni, lesi sitshalo singasiguqula sibe ama-carbohydrate, ushukela nesitashi. Lolu siko olwenziwe manje lusetshenziselwa ukondla nokukhula. Le nqubo yaziwa njenge i-photosynthesis, futhi omunye wemiphumela emihle ukuthi sibonga izitshalo esikwazi ukuphefumula, njengoba bexosha umoya-mpilo. Ugesi odalwa yizilwane - kufaka phakathi abantu- ukuze baphefumule, ngakho-ke baphile.
Manje, kwenzekani lapho ugula? Kungani kunconywa ukuthi ungabakhokhi baze bathuthuke? Yebo, lokhu kungenxa yokuthi izimpande zizongena emhlabathini (noma kusuka ku-substrate uma kutshalwe ebhodweni) kuphela ezikudingayo. Lapho zifakwa, Banikezwa ukunikezwa okwengeziwe kwezakhamzimba namaminerali okuqala kulimaze uhlelo lwempande bese kulimala sonke isitshalo. Kungaba yinto efana nokuthi uma siphoqa umuntu onesisu esibucayi ukuthi adle ipuleti elihle lamafrimu aseFrance nge-hamburger. Akucebisi 🙂.
Ukwenza umquba kubaluleke kakhulu ezitshalweni, kodwa kuphela kwabaphilile.
Ubuwazi ukuthi izitshalo zimunca kanjani izakhi zomzimba?
