Kwemakore akawanda, mhuka dzakashandisa kunyika inotonhora, uye kuti tembiricha yakaderera, uye kunzwisisa kwemasayendisiti okuwana zvokudya.

Polar nebere

Saka, chii mhando dzemhuka vanogara kuchamhembe? Polar nebere - ndicho chikuru kweArctic chikara, anogara pachigaro Earth. By simba rayo uye kukura mhuka idzi nyika inotonhora, wechipiri chete kuhama dzake shava vanogara Russia uye Alaska. Kazhinji, polar mabheya tunogara rongedza chando iri mumhenderekedzo yegungwa munzvimbo.

Mubhendi akawanda kumiswa plankton kuti mudye dzimwe mhuka nehove. Zviri Vamiririri ava fauna of ndiwo chikuru zvakatapwa polar unobereka. Kazhinji abate svikiro kadikidiki zvisimbiso. In kweArctic, mhuka idzi zvakakwana. Den Bheya rakamira pachando inoita chando. Vakadzi vanobereka mumwe kana kupfuura wayo.

Kuvhima Bheya rakamira pachando

Polar maperekadzi kundotsvaka zvisimbiso kumira makumbo ake hadzi uye Kufemba. Zvinokosha kucherechedza kuti mhuka idzi nyika inotonhora, mufananidzo uri anoshamisa, vanogona kunhuhwidza zvavo muzana kiromita. The Bheya rakamira pachando Kazhinji pedyo akatambudzwa leeward. Somugumisiro, mhepo kunounza munhuwi wacho getter kusvikira chisimbiso. Mabheya kunama rookery kambaira pamusoro dzinokara dzavo. Vakawanda vanoti mhuka iyi anofukidza dema mhino dzaro paw ake kuva asazivikanwa. Mushure Bheya rakamira pachando kusarudza munhu akuvara, iye anobata naye ari nounyengeri kanda.

Kana zvisimbiso patambo chando floe, pakabva kunova kunyange nyore. Bear swims kusvika wacho anongoti kuminyuka chisimbiso pedyo mvura.

The dzinonakidza zvikuru ndechokuti mhuka idzi Nordic vanokwanisa kunonotsa zvokudya kuna kwakanyanya nguva. Kazhinji, kweArctic chando chivharo iri clamped nenzira yakamanikana polynya muurayi hove huru. Bereka zvibhakera simba stun zvavo uye, achikanda musamudzivisa pamahombekombe Stacks muzvikochikari.

Uyewo, zvikara izvi hazvisi averse kudya walruses. Zvisinei, ndibate navo pachena Bheya rakamira pachando asingagoni. Pashure pezvose, ivo walruses simba zvikuru kupfuura ivo. Naizvozvo, mabheya vanomhanya kumativi rookeries uye hon'a. Chimiro walruses ari kutya dzinomhanyira kugungwa. Mabheya anoramba kunhonga akuvara uye vakadzvinyirirwa mhuka akura.
