The Organic nyika kweArctic Ocean (zvishoma)

Zvipenyu kuti kurarama kweArctic, vari kutambura. Very kutonhora kwekunze, chando kusingaperi, chando uye polar usiku 5-6 kwemwedzi gore - huru zviri utsinye ezvinhu ari polar uye Sub-peArctic nharaunda. The Organic nyika kweArctic Ocean yakatangwa muna ezvinhu aya akaoma. Munzira dzakawanda mukuru-Latitude zvinhu zvipenyu zvakasiyana kubva dzinodziya uye dzinopisa kumatunhu ari World Ocean (ıO). Simbisai uye zvishoma kutsanangura izvi zvinhu.

Utsinye dzinongoitika ezvinhu ari kweArctic

Chando uye chando kukunda kuArctic Circle, kuti makemikari nyika zvinoenderana kuti zvinhu izvi zvakasikwa. A mugove chinokosha kweArctic munharaunda yepasi inogarwa inotonhora mvura dzezvimwe necheni kune chando. Munyika dzakasiyana mukufamba inotevera nzvimbo mazita: kweArctic, Polar kana peArctic Ocean. Summer pamatunhu latitudes pfupi uye muchitonhorera, chando refu uye zvikuru. Precipitation inowira sechando, nhamba yavo zvachose iri diki - chete anenge 200 Rine mamiririta.

The Organic nyika kweArctic Ocean - ndiyo zvipenyu kuti agare pasi, muganhu uye vakawanda zvitsuwa kweArctic yamakungwa. mhuka dzakawanda uye dzimwe etuzvirimwa dzakashandisa yakaderera tembiricha iri chando uye chando. Sei izvi akaomarara vagari kwazvo nyika? Shiri uye mhuka kuti kugara kumusoro latitudes, kazhinji chena.

Zvose zvakasiyana-siyana nechepasi kunoratidza benthos. algae ichi, mollusks, coelenterates, vasiyana substrate ari pasherefu uye Continental materu, zvinokambaira crustaceans. Algae akatonga kelp uye fucus. Flowering chirimwa eelgrass inowanikwa muGungwa White. Mhuka Benthic Anonyanyowanika ukama invertebrates (makonye, sechipanji, gungwa anemones uye nyeredzi, clams, magakanje). Vanogona kutsungirira nemarwadzo kutonhora uye kwasviba pegungwa.

Pakati anenge 200 mhando phytoplankton, vakawanda kufanana diatoms.
Sparse Flora pamahombekombe egungwa uye vakawanda archipelagos aimiririra gymnosperms, maruva zvinomera uye lichens. Food ngetani zvinosanganisira zooplankton, zvomumvura invertebrates, hove, shiri, mhuka. Okupedzisira mapoka maviri vagere pachiwi uye muzvitsuwa, zvokudya pachavo kakawanda inowanikwa mumvura akasununguka kubva chando. Nokuti nyika neshiri kweArctic kunoratidzwa rudzi wakapfuma, uye "rookeries" ruzha Siyanisai nyika makemikari nyika kweArctic Ocean.

List dzemhuka kweArctic

Invertebrates: muramba cyan, Ophiuroidea "Gorgon musoro", clams uye crustaceans.
Zimbabwe Shark anomira pakati guru kukura hove. Zvimwe vamiririri fauna of hove: Sarimoni, herring, cod, knot, flatfish (kusanganisira Paltusova). Shiri: ptarmigan, Guillemot, Zizi, terns, gondo mhanza.

mhuka:

• toothed hove huru (beluga shato huru, narwhal);
• zvisimbiso (mbira, mitsetse, iwo chisimbiso, rakanga rakapfeka zvinovhara kumeso nemicherechedzo);
• walruses
• chena kana Bheya rakamira pachando;
• poro (caribou)
• Arctic mhumhi;
• musk nzombe;

• lemming.

Adaptations Zvirimwa uye mhuka kweArctic

The Organic nyika kweArctic Ocean dzakasiyana-siyana phytoplankton anenge sezvo kuchamhembe nzvimbo Atlantic uye Pacific. Sezvineiwo, vamwe algae nemaziso havadarowo kukwanisa photosynthesize kunyange chando. Somugumisiro, chena nomumativi akafuka greenish mashava firimu, uye chando ikanyauka nokukurumidza. mvura mwero inotonhora vapfumi ichiputswa okisijeni uye senitrogen, kana richikwidibira rinorema chapamusoro udzamu uchakwira zvakakodzera micronutrients kuti phytoplankton. Izvi zvinhu kusika zvakanaka mamiriro ezvinhu kukurumidza kukura nemaziso zvipenyu.

A namarudzi chiratidzo, chiratidzo izvo vanoziva makemikari nyika kweArctic Ocean - the Bheya rakamira pachando. Uyu ndiwo mumwe kupfuura pano zvikara; Adult male muviri rinosvika munhu kureba 2-3 mamita. Rinodya zvikurukuru pamusoro zvisimbiso, hove. White Bheya Arctic nedzimwe mhuka anokwanisa kuderedza muviri panguva yakaderera tembiricha. Vachikura zvishoma nezvishoma, asi unogona kusvika zvikuru hukuru uye vakwegura. Somuenzaniso, dzinopisa urchin kazhinji akararama makore 10, ane polar mhando angawanika makore anopfuura 60.

Mamiriro ekunze zvishoma manyoro mumakungwa yeEuropean chikamu kweArctic, saka nemiti uye fauna of vari kupfuma. Chinonyanya vakawanda ndiro kudzika Continental pasherufu. Asi pazuva rose chirimwa uye makemikari nyika iri murombo iri mhuka. Pakati zvikonzero - utsinye okunze, nokushaya chiedza chezuva uye kupisa pamusoro zvinomera, kushaya zvokudya mhuka.

Pfupiso kweArctic Ocean

Apasi coldest venyika gungwa anopindura 4 chete% yayo zvachose nzvimbo. KweArctic Ocean riri panenge pakati kweArctic. Nzvimbo muganhu chinhu zvimiso mutsetse - Arctic Circle (66 ° kufanana W ..). KweArctic harisi chete mvura dzezvimwe, asiwo chitsuwa, nemhenderekedzo makondinendi. Nzizi kweArctic Ocean - chimwe chezvinhu renguva kuerera munyika. Yerera kupinda Arctic mumakungwa; asi Yenisey, Lena, Ob, Pechora, Yana, Kolyma, Indigirka. Narrow Bering Strait Anopatsanura polar mvura Pacific. Muganhu pamwe Atlantic anomhanya kuburikidza Air Peninsula uye kumaodzanyemba Zimbabwe. On nharaunda kweArctic ndiye kuchamhembe kwavanogara danda.
