U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Gelitaanka: Halophiles, oo ay ku jiraan nooca Halobacterium, waxay ku nool yihiin deegaanno aad u cusbo leh sida harooyinka cusbada leh waxayna ka badan yihiin dhigooda bakteeriyada ee cusbada ka badan 20<unk>25%. Thermophiles waxay si fiican ugu koraan heerkul ka sarreeya 45 ° C (113 ° F), meelaha ay ka midka yihiin ilaha kulul; Hyperthermophilic archaea waxay si fiican ugu koraan heerkul ka sarreeya 80 ° C (176 ° F). Archaea Methanopyrus kandleri Strain 116 xitaa waxay ku tarmi kartaa 122 °C (252 °F), heerkulka ugu sarreeya ee la diiwaangeliyey ee noolaha kasta. Archaea kale waxay ku nool yihiin xaalado aad u aashito ama alkaline ah. Tusaale ahaan, mid ka mid ah acidophiles-ka archaean-ka ugu daran waa Picrophilus torridus, oo ku koraya pH 0, taas oo u dhiganta kobcinta 1.2 molar sulfuric acid. Adkaysigan deegaannada ba'an ayaa ka dhigay archaea diiradda mala-awaalka ku saabsan sifooyinka suurtagalka ah ee nolosha dibadda. Qaar ka mid ah deegaanada aadka u daran ayaa la mid ah kuwa ku yaal Mars, taas oo keentay in la soo jeediyo in microbes-ka noolaan kara loo wareejin karo meeraha meeraha meteorites. Dhawaan, dhowr daraasadood ayaa muujiyay in archaea aysan ku jirin oo keliya jawiga mesophilic iyo thermophilic laakiin sidoo kale ay joogaan, mararka qaarkood tiro badan, heerkul hooseeya sidoo kale. Tusaale ahaan, archaea waxay ku badan yihiin jawiga qabow ee badaha sida badaha qabow. Waxaa xitaa ka sii muhiimsan tiro badan oo ah archaea oo laga helay badaha adduunka oo dhan oo ku yaal deegaanno aan aad u daranayn oo ka mid ah bulshada plankton (sida qayb ka mid ah picoplankton). Inkastoo archaea-yadani ay ku jiri karaan tiro aad u badan (illaa 40% biomass microbial), ku dhowaad noocyada noocan ah lama go'doomin oo laguma barto dhaqanka saafiga ah. Sidaa darteed, fahamkeena ku saabsan doorka archaea ee deegaanka badaha waa mid aasaasi ah, sidaa darteed saameyntooda buuxda ee wareegga biogeochemical ee adduunka ayaa weli ah mid aan la baarin. Qaar ka mid ah Crenarchaeota badda ayaa awood u leh nitrification, oo soo jeedinaya in noolahaasi ay saameyn ku yeelan karaan wareegga nitrogen ee badda, in kasta oo Crenarchaeota badweynta ay sidoo kale isticmaali karaan ilaha kale ee tamarta. Waxaa kaloo jira tiro aad u tiro badan oo ah noocyada loo yaqaano Archaea  Su'aal: Heerkulkee ayaa lagu cabiri karaa habka mitirka?
