Kwenzeka ntoni xa iilwandle zingenanto?
Ifotosynthesis ilawula umthamo weoksijini womoya esiwuphefumlayo. Ukuba sitshabalalisa ulwandle, i-photosynthesis iya kuba yinto encinci kwaye ngoko kuya kubakho i-oxygen encinci
Aziyi kubakho nini iintlanzi?
Iintlanzi azihlali zodwa elwandle kangangeminyaka. Udityaniswe sisivunguvungu esikhulu senkunkuma yeplastiki. Ukuba asitshintshi nto ngoku, ngokutsho kweNational Geographic, zonke iintlanzi zinokuphela elwandle ngo-2048. Kwiminyaka engama-30 akusayi kubakho ntlanzi.
Yintoni omele uyenze ukuba zonke iintlanzi ezikwi-aquarium ziyafa?
Unobangela oqhelekileyo wokubulala iintlanzi bubushushu obugqithisileyo. Ngokufuthi ezi ntlanzi ziqubha kuphela ngokungenamdla, zilale emazantsi, okanye ziphefumlele phezulu phezu kwamanzi. Jonga isifudumezi sakho se-aquarium kwaye ulinganise iqondo lobushushu usebenzisa i-thermometer ye-aquarium.
Ngaba ulwandle luyingozi?
Esona sisongelo esikhulu esivela elwandle asiveli kwisilwanyana: kuqikelelwa ukuba abantu abangaphezu kwama-30,000 bafa kwimisinga eyingozi minyaka le. Oko kubizwa ngokuba zii-rip currents kwenziwa yimimoya evuthuza elwandle isiya emhlabeni. Ukuba iinduli zesanti okanye amatye ahambisa inkitha yamanzi ehlayo, imisinga iyakha.
Kwenzeka ntoni xa i-ecosystem yolwandle isiwohlokile?
Ukutshatyalaliswa kwephytoplankton neekorale kulwandlekazi lwehlabathi nako kuya kuthetha ukutshatyalaliswa kwabona bavelisi babalulekileyo beoksijini. Ilahleko yeentlobo ngeentlobo zezinto eziphilayo zaselwandle kudityaniswe nokuwohloka kwenkqubo yokuphilisana kwendalo esisiseko kwiilwandlekazi kusongela ukuphila kwalo lonke uluntu.
Ngaba singaphila ngaphandle kweentlanzi?
Ifotosynthesis ilawula umthamo weoksijini womoya esiwuphefumlayo. Ukuba sitshabalalisa ulwandle, i-photosynthesis iya kuba yinto encinci kwaye ngoko kuya kubakho i-oxygen encinci. Okokuqala, kwiintlanzi, zifa kuqala, kulandele thina bantu.
Ngaba intlanzi sisilwanyana?
Iintlanzi zizilwanyana ezihlala emanzini kuphela. Baphefumla ngeegill kwaye bahlala benolusu olunexolo. Zifumaneka kulo lonke ihlabathi, emilanjeni, emachibini naselwandle. Iintlanzi zizilwanyana ezinethambo lomqolo kuba zinomqolo, njengezilwanyana ezanyisayo, iintaka, izirhubuluzi kunye nezilwanyana ezihlala emanzini.
Ngaba Iintlanzi Zinokufa Ngenxa Yoxinezeleko?
Iintlanzi, njengabantu, zichaphazeleka ekusebenzeni kwazo ngoxinzelelo. Oku akubandakanyi impilo yezilwanyana kuphela kodwa kunye nokukhula okufanelekileyo kumfama weentlanzi. Uxinzelelo olusisigxina (ngengqiqo yoxinzelelo) lunokuphetshwa kuphela ngokuma okufanelekileyo.
Kutheni iintlanzi zifa ngolo hlobo nje?
Unobangela wokufa kweentlanzi zizifo zeentlanzi, ukungabikho kweoksijini, okanye ukunxila. Kwiimeko ezinqabileyo, ukuguquguquka okunamandla kubushushu bamanzi kukwabangela ukuba iintlanzi zibulale. Amaziko ombane ombane abangela intlaninge yeentlanzi ezifileyo; Ii-eels zichaphazeleka kakhulu ngenxa yobukhulu bazo.
Kutheni intlanzi yam entsha endisandul’ ukuyithenga isifa?
Hayi, inokuba yintlanzi engakhethi cala. Oku kubangelwa kukuba iintlanzi zijongene neentsholongwane ezingaziwayo kodwa kungekhona ngokwenene iintsholongwane ze-pathogenic kwitanki enebhaktheriya engaziwa kubantu abatsha, kodwa ngokwenene kungekhona iintsholongwane ze-pathogenic.
Ngaba intlanzi ibalulekile?
Iintlanzi ziyinxalenye ebalulekileyo yeendawo zokuhlala zaselwandle. Zinxulumana nezinye izinto eziphilayo ngeendlela ezintsonkothileyo - umzekelo ngokusebenzisa iiweb zokutya. Oku kuthetha ukuba ukuloba ngokunzulu akukhokeleli kuphela ekuphelisweni kweentlobo zentlanzi kodwa kuchaphazela uluntu luphela.
Kutheni kukho iintlanzi?
Iintlanzi ziyinxalenye ebalulekileyo yoluntu lwaselwandle. Yaye abantu bebenxibelelene ngokusondeleyo nazo kangangamawaka eminyaka ngenxa yokuba zibanika ukutya. Izigidi zabantu kwihlabathi jikelele ngoku ziphila ngokuthe ngqo ekulobeni okanye ekulobeni iintlanzi.
Kutheni sifuna iintlanzi?
Intlanzi ithathwa njengesempilweni kuba iqulethe i-omega-3 fatty acids ebalulekileyo. I-German Nutrition Society (DGE) ngoko ke incoma ukutya iintlanzi kabini ngeveki. Oku kukwanyusa usetyenziso lonyaka lwentlanzi ngomntu ngamnye.
Ngaba intlanzi ingagqabhuka?
Kodwa ndiyakwazi ukuphendula kuphela umbuzo osisiseko kwisihloko nge-YES ukusuka kumava am. Iintlanzi zinokugqabhuka.
Ilala ixesha elingakanani intlanzi?
Uninzi lweentlanzi zichitha ixesha elininzi leeyure ezingama-24 kwindawo yokulala, apho imetabolism yazo “iyavaleka” kakhulu. Abemi be-coral reef, umzekelo, barhoxa kwimiqolomba okanye kwimingxuma ngexesha lokuphumla.
Intlanzi yenza ntoni imini yonke?
Ezinye iintlanzi zasemanzini acwengileyo zitshintsha umbala womzimba zize zibe ngwevu-luthuthu ngelixa ziphumle emazantsi okanye kuhlaza. Kakade ke, zikho neentlanzi zasebusuku. I-Moray eels, i-mackerel, kunye ne-groupers, umzekelo, baya kuzingela ngorhatya.
Yintoni eyityhefu kwintlanzi?
I-Nitrate iyityhefu kuphela kubahlali bakho basechibini kwiidosi eziphezulu. Ngokuqhelekileyo, intlanzi iyafa ngenxa yetyhefu ye-nitrite, ngoko ke i-nitrate yetyhefu ayinakwenzeka. Ekubeni i-nitrate sele iqulethwe kumanzi ompompo, kufuneka ubuze i-waterworks enoxanduva ngexabiso elisisiseko.
