# Umphumela Wokucindezeleka Ekukhuleni Kwezitshalo Izitshalo ziyingxenye ebalulekile yokuphila eMhlabeni, zisekela izimiso zemvelo eziningi futhi zihlinzeka ngokudla okubalulekile kanye nemithombo yomoya-mpilo yezinto eziphilayo. Kodwa-ke, njengezinye izinto eziphilayo, izitshalo azivikelekile ezimweni ezahlukahlukene zokucindezeleka ezingavimbela ukukhula kwazo. Kulesi simo, ukucindezeleka ezitshalweni kuhlanganisa izici ezahlukahlukene… Funda kabanzi

Isihloko: I-Deep Sea Ecology kanye Nokuphila Kwayo Isingeniso Ulwandle olujulile lungenye yezingxenye eziyimfihlakalo kakhulu nezingaqondakali kahle zezindawo zemvelo zoMhlaba. Ekujuleni okungaphezu kwamamitha angu-200, ulwandle olujulile lumboza cishe u-65% wobuso boMhlaba, okwenza kube yindawo enkulu kodwa engakahlolwa kahle. Yilapho ukuhlukahluka kolwandle kufinyelela khona esicongweni salo, ngezinhlobo ezihlukile... Funda kabanzi

Ubuchwepheshe Bokulungisa Izinto Eziphilayo: Isixazululo Semvelo Sokuhlanzwa Kwemvelo Ukulungisa izinto eziphilayo ubuchwepheshe obuhilela ukusetshenziswa kwezinto eziphilayo, njengezinambuzane ezincane, izitshalo, noma ama-enzyme azo, ukususa noma ukuqeda ukungcola endaweni engcolile. Lobu buchwepheshe bunikeza indlela ephephile, esebenza kahle, futhi enobungani nemvelo kunezindlela zokuhlanza zendabuko, ezivame ukusebenzisa amakhemikhali angalimaza imvelo. … Funda kabanzi

# Izinzuzo Zamagciwane Okuphila Konke Amagciwane avame ukuhlotshaniswa nemiphumela emibi nebhubhisayo. Ubhubhane lomhlaba wonke olufana nalolu olubangelwa yigciwane le-SARS-CoV-2, elaziwa kakhulu ngokuthi i-COVID-19, luqinisa lo mbono. Kodwa-ke, phakathi kwalesi sici esibi, kunezici ezinhle ngamagciwane okufanele ziqashelwe. Eqinisweni, amanye amagciwane abe negalelo elikhulu emikhakheni eyahlukene… Funda kabanzi

Umjikelezo We-Nitrogen: Ukuphila Ngokuvumelana Emhlabeni Umjikelezo we-nitrogen ungomunye wemijikelezo ebaluleke kakhulu ye-biogeochemical eMhlabeni, ohilela ukudluliselwa kwe-nitrogen ngezindlela ezahlukene zamakhemikhali phakathi komkhathi, inhlabathi, amanzi, nezinto eziphilayo. I-nitrogen iyinto ebalulekile, yakha cishe u-78% womkhathi woMhlaba ngesimo segesi ye-nitrogen (N2). Nakuba iningi, lolu hlobo lwe-nitrogen alukho… Funda kabanzi

# Ithonya Lezinto Eziphilayo Eziphilayo Ezindaweni Eziphilayo ## Isingeniso I-ecosystem iyinethiwekhi eyinkimbinkimbi ehlanganisa zonke izinto eziphilayo (i-biotic) kanye nendawo ezungezile (i-abiotic) endaweni ethile. I-ecosystems isebenza njengeyunithi eyisisekelo ye-ecosystem lapho ukuxhumana phakathi kwezingxenye ze-biotic ne-abiotic kwenzeka khona futhi kwakha ibhalansi yemvelo. Izinto eziphilayo zonke ziyizinto eziphilayo endaweni ezungezile, okuhlanganisa nezilwane, … Funda kabanzi
