Yini enquma umthamo wokuthwala we-ecosystem?
Impendulo ithi: Izinqumo ze-Abiotic ne-biotic.
Amandla okuthwala we-ecosystem anqunywa izinto ezimbalwa, okuhlanganisa ukutholakala kwezinsiza, inani lezinhlobo ezikhona, kanye nokusebenzisana phakathi kwezinhlobo zezilwane.
Izinsiza ezifana nokudla, amanzi, ukukhanya kwelanga, nendawo yokukhosela zilinganiselwe kunoma iyiphi indawo ezungezile, futhi uma lezi zinsiza ziba yindlala, amandla okuthwala aleyo ndawo angancipha.
Inani lezinhlobo ezikhona lingaphinda libe nomthelela ekuthwaleni; Lapho izinhlobo zezilwane ziqhudelana ngezinsiza, zinganciphisa inani elitholakala kwabanye, ngaleyo ndlela zinciphise umthamo wokuthwala.
Ukwengeza, ukusebenzisana phakathi kwezinhlobo zezilwane ezifana ne-predation kanye ne-parasitism kungaphazamisa umthamo wokuthwala.
I-Predation inciphisa inani labantu emphakathini kuyilapho i-parasitism ithinta kokubili izilwane ezizingelayo kanye nezisulu, kunciphisa umthamo wokuthwala.
