Intambo yeTrophic: umzekelo oqhelekileyo we-tundra. Ietyunithi zokutya kwindawo ye-tundra

Le ngcamango ingabizwa ngamagama ahlukeneyo: i- trophic chain, ukhenketho lokutya, utyane lokutya , izixhumanisi zendalo-nto yinto engatshintshiyo. Izimo zemozulu zitshintsha, iiflethi kunye nokutshintsha kwezilwanyana, kodwa intsingiselo ayiguqukanga - namhlanje udla ukutya, kwaye kusasa wena-ukutya.

Iimpawu ze-tundra

Ummandla wendalo, ophakathi kwe-arctic ne-taiga, inqongophala kakhulu kwiifle kunye nezilwanyana. Akunjengokushiywa njengeArtictic, kodwa ngeendawo ezifudumalayo zemozulu akufanelanga ukuba uthelekise. Umhlaba utywala kunye nesigxina, kuphela i-mosses ne-lichens ikhula kwi-moss, kwaye nangona kunjalo ayikho yonke indawo, i-permafrost ayivumeli. Ngokusondeleyo kumhlaba we-taiga, izihlahla ziqala, kwaye ngamanye amaxesha unako ukudibana ne- willow or birch. Imfuyo ayininzi kakhulu, kwaye kuyimfuneko ukunyusa phantse bonke abameli belizwe lezilwanyana isichazi esithi "i-polar", i-hare iyinkomo, i-fox okanye ibhere, kunye ne-owls. Noko ke, i-Deer, ngasentla.

Ikholeji yokutya

Ngezantsi umzobo wesiphaluka sesondlo sesimo se-tundra. Isithomboniso sibonisa ngokubonakalayo.

Akubandakanyi zonke izilwanyana, kuphela eziqhelekileyo. Ukuba awuyikunyamekela le nto inqabileyo kule ndawo i-lemmings kunye ne-musk zeenkomo, ngoko ke iskimu, efana ne-tundra, ukhenketho lokutya lulandelayo. I-Mosses kunye ne-lichen zidliwa yi-herbivores: iihalar pores kunye ne-reindeer. Oku akuphakamisi imibuzo. Ubunqwenelekayo bekimpawu zeskimu kwi-tundra, ukhenketho lokutya yilo: ezinye izilwanyana (izimpungushe ze-arctic kunye neebhere), ngenxa yokungabi naso kwesondlo sesilwanyana rhoqo, zidla izilwanyana kunye nama-mosses.

Ngezantsi umfanekiso. Kukho ummeli kuwo, ngaphandle kweyiphi na isiphaluka se-chain chain yokutya ye-tundra ayiyi kubonakala ngathi. Liyindawo ehlala kuyo ehlobo.

Ubusika kwi-tundra bude kwaye bunzima. Ihlobo lifutshane kakhulu, liqulethe intwasahlobo ehamba ngokukhawuleza kunye nezilwanyana eziluhlaza kunye nekwindla. Ngaphezu koko konke kulula. Iskimu sesimo se-tundra, ukhenketho lokutya ufana nezinye: i-herbivores encinci (i-polar hares, i-lemmings efanayo) idliwa yizilwanyana ezincinci - iibhokhwe, izimpungushe okanye iingcuka. Iilbivores ezinkulu (izilwanyana ze-musk kunye namaxesha angamaxesha ahlangane nazo) zidliwa yiingcuka kunye neebhere.

Kukho izithako ezininzi kufuphi neketeni. Lawa onke amaxhoba awazingabelaniyo, kodwa kwindawo engokwemvelo ayenzanga ukudibanisa: i- polar owl, i- Arctic fox, ingcuka. Kulo mfanekiso ungezantsi, umlwanyana uboniswa, apho umzila wesiphaluka we-tundra, ukhenketho lokutya lubonakala luphelele. Yibhere le polar endaweni yokuhlala.

Endaweni yokugqiba

Ukuzaliswa kwe-tundra kunye neeflora kunye nezilwanyana zininzi kakhulu kunokuba zichaziwe kwinqaku. Liyizinambuzane ezixhaphaza iindawo ezinqabileyo kwixesha elifudumeleyo. Zikhona ezinye iintaka ngaphandle kweebhokhwe ezondla kulezi zinambuzane. Izilwanyana ezisuka kwezinye iindawo zemvelo zihamba apha. Kodwa konke oku akukuchaphazeli ukutya okuphambili, uphawu lwe-tundra. Iziqhagamshelo eziphambili zekholethi zaziwa ngoku.
