Ubuchwepheshe Bezinto Eziphilayo kanye Ne-Zootechnology: Intuthuko kwezesayensi eminyakeni embalwa edlule ishintshe indlela abantu abakhiqiza ngayo ukudla, balondoloze impilo yezilwane, futhi baphathe izinsiza zezinto eziphilayo ngendlela ephumelelayo. Izinkambu ezimbili ezidlale indima ebalulekile kulolu shintsho ubuchwepheshe bezinto eziphilayo (i-biotechnology) kanye ne-zootechnology (isayensi nobunjiniyela bokufuya izilwane). Ubuchwepheshe bezinto eziphilayo buhlinzeka ngezindlela ezahlukene zokuphatha, ukusebenzisa, kanye… Funda kabanzi

Izinzuzo Zezitshalo Ezitholakala Emvelweni Zezinhlelo Zemvelo Izitshalo ezitholakala emvelweni ziyizinhlobo zezitshalo ezikhula ngokwemvelo endaweni ethile kuphela futhi ezingatholakali kwenye indawo. Ukuba khona kwazo kuvame ukuhlobene eduze nezimo zemvelo zendawo—njengesimo sezulu, uhlobo lomhlabathi, ukuphakama, kanye nokusebenzisana nezilwane ezizungezile kanye nezinambuzane ezincane. Ngenxa yalokhu kuhlukile, izitshalo ezitholakala emvelweni ziyingxenye ebalulekile yobunikazi besifunda… Funda kabanzi

Umphumela Wokungcola Kwezitshalo I-Photosynthesis inqubo eyisisekelo evumela izitshalo ukuthi zikhiqize ukudla (i-glucose) kusuka ku-carbon dioxide (CO₂) kanye namanzi (H₂O) ngosizo lokukhanya kwelanga. Le nqubo ayinqumi nje kuphela ukukhula kwezitshalo kanye nokukhiqiza kodwa futhi igcina ibhalansi ye-ecosystem ngokukhulula umoya-mpilo. Kodwa-ke, kwandisa ukungcola komoya ngenxa yemisebenzi yezimboni, ezokuthutha, ukushiswa kwemfucuza, kanye nemililo… Funda kabanzi

Uhlelo Lokuzala Ezitshalweni Eziqhakazayo Izitshalo eziqhakazayo, noma ama-angiosperms, yiqembu lezitshalo elihlukahlukene kakhulu eMhlabeni. Ukusabalala kwazo kabanzi ezindaweni zokuhlala ezahlukahlukene kungenxa yezinhlelo zazo zokuzala ezisebenza kahle nezivumelana nezimo. Ezitshalweni eziqhakazayo, ukuzala kwenzeka ikakhulukazi ngezimbali, izitho zokuzala ezivumela ukuvundiswa kwempova, ukukhulelwa, ukwakheka kwembewu, kanye nokukhula kwezithelo. Lesi sihloko… Funda kabanzi

I-Ecology ye-Peat Swamp kanye nokuhlukahluka kwayo Ama-peat swamp angenye yezindawo zemvelo eziyingqayizivele kakhulu emhlabeni. Akhiwa ngezinto eziphilayo eziqongelelwe—ikakhulukazi izinsalela zezitshalo—ezicwiliswe emanzini isikhathi eside, okuholela enkambisweni yokubola kancane. Lokhu kuqoqana ekugcineni kukhiqiza ungqimba olujiyile, olumnyama, olune-asidi, nolucebile ngekhabhoni lwe-peat. E-Indonesia, ama-peat swamp atholakala ngobuningi… Funda kabanzi

Ubuchwepheshe Bezinto Eziphilayo Nobezilwane: Intuthuko kwezobuchwepheshe bezinto eziphilayo nobezilwane ilethe izinguquko ezinkulu endleleni abantu abaqonda ngayo impilo, ukuvimbela izifo, nokuthuthukisa impilo yezilwane nabantu. Enkathini yanamuhla, insimu yezinto eziphilayo ayisagcini ekubonweni okuvamile kwezinto eziphilayo, kodwa isandisiwe yaze yafaka phakathi ukuguqulwa kwezakhi zofuzo, ukuhlaziywa kwama-molecule, ubuhlakani bokwenziwa, ngisho namadivayisi okuxilonga okusheshayo. Okwamanje… Funda kabanzi

Izinzuzo Zezilwane Ezitholakala Emvelweni Yezinhlelo Zemvelo Izilwane ezitholakala emvelweni ziyizilwane ezitholakala ngokwemvelo endaweni ethile kuphela futhi azihlali endle kwenye indawo. Lokhu kuhlukile kungabangelwa umlando we-geological, isimo sezulu, ukuhlukaniswa kweziqhingi, kanye nezimo ezithile zokuhlala. I-Indonesia ingenye yamazwe anezinga eliphezulu lokutholakala kwezilwane, ikakhulukazi ngenxa yesimo sayo se-archipelagic... Funda kabanzi

Ithonya Lemvelo Ku-Physiology Yezitshalo I-Physiology yezitshalo ifunda ukuthi izitshalo zenza kanjani imisebenzi yazo yokuphila, kusukela emanzini kanye nokumuncwa kwezakhamzimba, i-photosynthesis, ukuphefumula, ukukhula, kanye nokuzala. Azikho kulezi zinqubo ezenzeka endaweni engenamuntu. Izitshalo zihlala endaweni ethile futhi zincike kakhulu ezimweni ezizungezile. Ngakho-ke, izinguquko ezicini zemvelo—njengokukhanya, izinga lokushisa, amanzi, … Funda kabanzi

Indima Yama-bacteria Enqubweni Yokuvubela Ukuvubela kungenye yezindlela zobuchwepheshe zokudla ezindala kakhulu ezisetshenziswa abantu ukucubungula, ukulondoloza, nokuthuthukisa ukunambitheka kokudla. Le nqubo isebenzisa umsebenzi wama-microorganisms—ikakhulukazi ama-bacteria kanye nemvubelo—ukuguqula izingxenye zamakhemikhali ekudleni zibe ama-compounds amasha azinzile, aphephile, noma anambitheka kakhudlwana. Phakathi kwama-microorganisms ahlukahlukene ahilelekile, ama-bacteria… Funda kabanzi

I-Ecology Yezwe Lasendle Nokuphila Kwalo I-Rangeland—engalinganiswa nezimila zotshani, i-savanna, noma indawo yokudla—ingaphezu nje kwendawo eluhlaza lapho imfuyo idla khona. Iyindawo eyinkimbinkimbi: eyakhiwe ukusebenzisana phakathi kwenhlabathi, amanzi, isimo sezulu, izitshalo, izilwane, izinto ezincane, kanye nabantu abayisebenzisayo. I-ecology yezwe lasendle ifunda ukuthi zonke lezi zinto zihlangana kanjani… Funda kabanzi
