Izilwane ezinomsoco - isigaba esikhethekile emhlabeni jikelele

Ukuphila kwezilwane yingxenye ebalulekile yemvelo kanye nezinqubo ezenzeka kuwo. Ukubamba iqhaza ezinhlelweni eziphilayo kanye namaketanga okudla kuyisidingo sabamele bayo. Izilwane eziningi zithuthukisa ukukhiqizwa kwezitshalo, futhi lezo, zibuye zibe ukudla kwezilwane. Lena inyunyana ehlanganisa izilwane ezinomdlavuza nezinye izakhamuzi zasendle.

Izwe lezilwane lihlukaniswe ngenani elikhulu lezigaba - izinhlobo, subspecies, oda, amakilasi. Phakathi kwazo yizilwane ezinomsoco - labo abamele izinyamazane ezidla ngokudla kuphela kwezitshalo. Bangabantu abathengi bokuqala bokuthenga ngaphakathi kokudla.

Isici sesimiso sokugaya ukudla kwalezi zithunywa zezwe elizungezile yiyona eyinhloko ye-enzyme yokudla i-amylase. Ezinye izilwane ezinomsoco zine-enzyme ephula i-cellulose. Lokhu kubenza bakwazi ukugaya kalula ukudla kwesitshalo.

Izilwane ezinomsoco ziyizinto eziphambene ngqo nabameleli abadliwayo bemfuyo. Ngokuyinhloko, lezi zigaba zingahlukaniswa izilwane eziphakeme. Izilwane ezincane, ezincane kakhulu kunzima ukufakazela omunye noma omunye wazo, ngoba ngokuvamile kuvamile ngisho nokuba yizizwe zezilwane noma izilwane. Bona ngokwabo bakhonza njengezilwane eziningi.

Ukuhlukanisa ngamaqembu ngohlobo lokudla kunzima futhi ngezizathu eziningana. Abanye abamele umhlaba wezilwane bangashintsha imikhuba ehlobene nokudla ngesikhathi sokuphila kwabo. Futhi, eziningi zazo zingu-omnivorous. Isibonelo, ezinye izibungu ezihamba phambili zihola impilo ye-parasitic kubamele bezilwane, ezinye zihlala endaweni yamahhala, futhi ingxenye encane yazo idla izitshalo. Okufanayo kusebenza nezibungu: ezinye zazo ziyi-parasites futhi zihlala ngezindleko zezilwane, kanti ezinye zihlala ezitshalweni.

Kunezimo eziningi ezinjalo phakathi kwabamele izinkomo. Isibonelo soshintsho ekudleni ngesikhathi sokuphila yi-frog. Lapho umuntu esekhulile, udla ukudla okuvela emfuyweni, kanti i-tadpole yayo iyinzalo (idla ama-algae). Kulezi zilwane ezinomdlandla zingabizwa ngokuthi i-koalas, ama-sloth, ama-kangaroo, ama-whale, amanye ama-parnopalhis, wonke ama-proboscis, ama-daisies namabhantshi.

Ama-Ungulates (amahlathi, ihlane, ama- steppe) iningi labo futhi angabasekilasini. Zonke zidla ukudla okutshala, kodwa uma zidla ukudla okuhlukile, khona-ke ngobuncane kakhulu, ezingafanani nomthamo wezitshalo ekudleni kwazo. Ukuvikela ukuhlasela, ama-ungulates amaningi anikezwa izimpondo, ama-bone formations ekhanda. I-Rhinoceroses inophondo olutholakala ekhaleni. I-saliva yezilwane ezinomsoco ayihlukanisi i-ptyalin. Ngokuyinhloko kuhloswe ekudleni kokudla.

Ukudla kwemifino yemvelo kunzima kakhulu ukugaya. Ukwenza lolu hlelo lubizwa ngokuthi isakhiwo esiyinkimbinkimbi sesisu, esinezilwane ezinomsoco. Ezingxenyeni zalesisigaba, iqukethe inetha, uhlamvu, incwadi kanye ne-abomasum. Lokhu kukuvumela ukugaya kalula ukudla okucebile kwe- fiber. Le nqubo iyenzeka ngezigaba eziningana: kusukela ebubini, ubuhlalu obuhlotshwe kabi bungaphinda buphonswe emgodini, bese kungena emlonyeni - isilwane "sihlambalaza." Ukwehliswa ngamathe, ukuhlolisiswa kahle ukudla okwamanje akuwa emkhakheni, kepha ugeleza phansi umfula bese uthola inetha encwadini, bese ungena ku-abomasum. Kusukela ku-abomasum, iphonswa ngaphandle kwezingxenye ezincane emathunjini amancane, lapho izakhi zingena egazini.

Izilwane zemifino zinemibono ekuhlukeni kwamazinyo. Zibonakala ngamazinyo anekhanda eliphansi futhi igebe elikhulu emathangeni. Abaningi babo abanawo ama-incisors. I-Herbivores inezinhlanzi ezinamandla kakhulu zokuhlakulela ezibhekene nokugubha ukudla okunzima kwezitshalo.
