Driving matla oa potoloho bath arctic ea lehoatata: embodiments, likarolo tsa motheo

Hangata lithuto tsa histori tsa tlhaho fuoa mosebetsi oo: ". Haha phepelo ketane sekemeng" Sekolong tsebo ka etsa sena baithuti sekolong se ka sehloohong. mofuta ona wa mosebetsi oa thusa ho hlahloba hore na seithuti se tlhahisoleseding e mabapi le liphoofolo le limela tsa sebakeng sa ho khetheha. Kaha o lokela ho ba le lesedi ka ho lekaneng akaretsang, mosebetsi ona ha leseli tebelwa. Sehlooho seo se tla fuoa matla oa potoloho-thalo, bath ea lehoatata arctic, hape fa tlhaloso e le hlalosa melao-motheo ea kaho.

Phepelo ketane: ke eng?

Ke seo ketane lijo? Ho ke ho sephiri hore bophelo polaneteng e potolohang: ba bang ba phelang ba tsoetsoe ba ho fana ka thepa ea manyolo bakeng sa ntshetsopele le ho kgolo ya ba bang. lintho tse phelang tse ngata - semela-ho ja, ho batho ba bang (ho akarelletsa le batho ba) - tse jang.

Qalong ea e mong le e ketane ba dimela (plankton kapa, tabeng ea tikoloho metsing), o bitswang - the likokoanyana phytophage kapa liphoofolo. Ka holimo - ka liphoofolo tse li jang. Ho thahasellisang ke hore, haeba ho fading elements oa potoloho bonyane le nngwe, ho na le ho fela 'me ba bang, hobane mabapi e felisoa. A re hlahlobeng mohlala o itseng.

Mokhoa oa ho etsa phepelo ketane temperaturdiagramm, tloaelehileng steppe libaka? Ho qala ho etsa qeto ea hore limela le liphoofolo li lule tšimong ena. E laoloa ke joang komello manganga le lipalesa, tse kang masiba joang kapa lijo-thollo. Har'a liphoofolo ka steppe e laoloa ke litoeba. Ba Hlekefetsang ba Bang - liphokojoe kapa lintsu, liphooko. Mona ke mehlala ea liketane: Grass - lerutle - Frog - e steppe ntsu. Kapa ena: lijo-thollo - toeba-vole - phokojoe.

Arctic ea lehoatata: makgetheng klimate

Pele re bua ka hore na ba phepelo ketane temperaturdiagramm, bath ea lehoatata arctic, lokela ho khetholla libaka ena boemo ba leholimo. sebaka sena e futsanehileng haholo ka boemo ba leholimo e sehlōhō ka limela le liphoofolo.

Lefatše koahetsoeng ka mokato oa permafrost, kahoo hoo e batlang e ha ho na limela: feela seoelo joang, mosses le boriba. Hoo e ka bang e tšoanang e ho joalo le ka liphoofolo tse tsa lefatše: lemmings feela, liphokojoe arctic le libere Polar. Ho naha ka ho ngotsoe ke likolone nonyana - ka likhoeli tse ea lehlabula, linonyana etsa lihlaha tsa bona ka lilomo e.

Ka metsing a Leoatle la Arctic le baahi ka ho walruses le liqibi, le mefuta e meng ea litlhapi arctic.

Plankton - tlhapi - litiiso - Polar bere

A re ke re hlahlobeng hore na lintho tse phelang li fepa ka ka sebakeng seo. Oa potoloho pele phepelo oa potoloho bath arctic ea lehoatata e qala ka plankton. Sena dikokwanyana hore ba lule ho metsi. Ba ke ke ba hanela phallo, kahoo e phaphametse lokolohile ka lenaneng la metsi. mefuta e makholo a mabeli ea phytoplankton tse hlahisoang sebakeng sena (ho ke ke khona ho tala) le ka boholo ba zooplankton (protozoans le 'ngoe-e nang le sele le crustaceans).

Next kgokahanyo - litlhapi. Ea eona e leng Leoatleng la Arctic leo ho ahiloeng ho ke tse fetang 150 mefuta e. Har'a bona ke baemeli ba ea cod, litlhapi tsa salmon, flounder, herring. Kaofela ha bona ba ikamahanya le maemo ho maemo a boima ao ba ka leboea.

Fish iphepe ka liqibi. liphoofolo tse anyesang tsena na mapheo-leoto leo ka lona susumelletsa hantle tlas'a metsi. Front manala a eona.

Sena oa potoloho phepelo matla ka libaka arkticherskih mahoatateng tšoeu fella bere. Ke liphoofolo tse li jang kholo ka ho fetisisa ka ho Arctic hase feela, empa le bohle lefatšeng ka bophara. Palo e kahodimodimo boima a phoofolo a - ton, ka motho ka mong bolelele fihle limithara tse tharo. Ba fepa ka liqibi. Etsa ka tsela ena: lalla bakeng sa liphofu, setorouku ka paws e matla otla ka hlooho (stun) le hulanyetsa ka ntle ho lebōpong.

Sedge - Lemming - phokojoe

E mong oa potoloho-thalo tsa matla a bath ea lehoatata arctic e qala ka sedges. Sena ke setlama feela hore e ntse e hōla sebakeng seo. Leha dimela ke a ikokobelitse, 'me a koahela sebaka bona e nyenyane haholo.

Sedge ja litoeba. Ka Arctic, sehlopha sa bona se emeloang ke lemmings. Tsena liphoofolo tse nyenyane, le leloko la hamsters ka ja ka makhetlo a mangata boima ba sona. A 'mele tse nyenyane haufi le litsebe tsa hlooho le maoto stubby - tsena ke litšobotsi tsa qothomang ena. Lemming boea mala fapana ho itšetlehile ka nako ea selemo: ho tswa ho ea bohlooho-sootho ho hotetsa ka ea lehlabula, hoo e ka bang tse tšoeu mariha.

Ka holimo a tsa ketane phokojoe Polar - phokojoe. From sehlopha sa hae bileng a amanang - phokojoe ba tloaelehileng - ho liphoofolo tse li jang o na le 'mele ho feta stocky, lekaneng ho sefeneng le likhetla bao e seng a hlobaetsang le tsebe, ho tsoa morui, fluffy boea ba hoo e ka bang sa bonahale. Ka kakaretso, ho phokojoe ha ikhule ho tloha ha ho na limela, ha ho na liphoofolo. O ka ja, tse kang cloudberry le litoeba. Fox ha ikhule le tlhapi, ka lebaka le itseng tsielehile.
