Zonke izinto eziphilayo zifuna izondlo kunye neeminerali ukuze ziphile. Uhlobo ngalunye luneendlela zalo zokufezekisa oku kwaye, nangona izityalo zingenazandla okanye imilomo, zikwaphuhlisile iqhinga elisebenzayo lokukhula. Kodwa, oko ikukuthi?
Ngokuqinisekileyo iyakothusa indlela indlela izityalo ezifunxa ngayo izondlo.
Kwaye konke kuqala apha, ngeengcambu. Ngokwesiqhelo baya kuhlala bephantsi komhlaba, kodwa kukho ezinye iintlobo ezinokuthi iingcambu zazo zibonakale, ubuncinci, zikhula ngaphezulu komhlaba, njengoko kunjalo ngeFicus umzekelo. Iingcambu, kuba imbewu iyantshula, zineenjongo ezimbini kuphela: ukubamba isityalo emhlabeni kwaye ukufunxa ukufuma bonisa kuyo. Benza kakuhle kangangokuba kukho iintlobo ekufuneka zityalwe kumgama okhuselekileyo ukusuka kwimibhobho, kumadama okudada, kunye neminye imithombo yamanzi.
Yonke into abayifunxa emhlabeni (amanzi kunye neeminerali ezifumaneka kuyo) yaziwa ngegama lencindi eluhlaza, ehanjiswa emagqabini. Sakuba silapho, kwaye sibulela icarbon dioxide kunye namandla avela elangeni, isityalo singakuguqula sibe ziicarbohydrate, iswekile kunye nestatshi. Le ncindi, eyenziwe ngoku, isetyenziselwa ukondla nokukhula. Le nkqubo yaziwa njenge ifotosinthesis, kwaye enye yezona ziphumo zibalaseleyo kukuba enkosi kwizityalo esinokuziphefumla, kuba bakhupha ioksijini. Irhasi esizizilwanyana-kubandakanya abantu- kufuneka sikwazi ukuphefumla kwaye, ngenxa yoko, siphile.
Ngoku, kwenzeka ntoni xa ugula? Kutheni le nto kucetyiswa ukuba ungabahlawuli de baphucule? Ewe kungenxa yokuba iingcambu ziya kufunxa emhlabeni (okanye kwi-substrate ukuba ikhule embizeni) kuphela into abayifunayo. Xa banconywa, Banikwa ukongezwa okongezelelekileyo kwezondlo kunye neeminerali ezonakalisa kuqala inkqubo yeengcambu kunye nesityalo sonke. Ingayinto enjengaleyo ukuba sinyanzela umntu onesisu esibuthathaka ukuba atye ipleyiti entle yeefries zaseFrance kunye nebhamburger. Akucebisi 🙂.
Umgquba ubaluleke kakhulu kwizityalo, kodwa yezo zisempilweni kuphela.
Ngaba uyazi ukuba izityalo zizifunxa njani izondlo?
