Doorka xoolaha ee dabiiciga ah

Geedaha waa ku saleysan nolosha on Earth. Waxay qarsan walxaha kala duwan ee dabiiciga ah organic, taas oo loo sameeyay ku dul nuugista ee cusbada macdanta iyo biyaha, carbon dioxide iyo tamarta qoraxda. Dabcan, ee muhiimada dhirta ee dabiiciga ah waa weyn yahay, waa cunto nuujiya, iyo il of ogsijiin. Waa maxay doorka xoolaha ee dabiiciga ah? Naasley ma tahay qayb yar oo ka mid ah dabeecadda, oo gubtay, walxaha by dhirta. Mid ka mid ah hawlaha ugu muhiimsan ee xayawaanka ku dhex jira jawi dabiici ah - waa in ay ka qayb wareegga ah ee walxaha, oo aan wixii aan ku noolaan kari waayeen shaqeeyo wax on Earth.

Doorka xoolaha ee dabiiciga ah

organisms Complex in hannaanka wax loo qaybin karaa saddex kooxood:

- saarayaasha - dhirta cagaaran in ay soo saaraan organic imanaysa alaabta imanba,

- consuments - xoolaha in ay ku quudiyaan on dhirta ama cuntada xoolaha, processing, ka dibna kala maalkii organic in dhumucda nooca ciidda ama ay dusha;

- decomposers - fungus iyo bakteeriyada, taas oo loogu badalo oo dhan walxaha organic ka dhasha nolol iyo xayawaanka iyo dhirta ee gaasaska iyo macdanta cusbada.

Iyadoo la raacayo, cusbada iyo gaasaska dib loo isticmaali karaa xididdada iyo caleemaha dhirta. Taasi waxa ay qarka u saaran baaskiil tamarta iyo walxaha dabiiciga ah ee la noolaha.  

Waa maxay doorka xoolaha ee dabiiciga ah?

Shaqooyinka xoolaha ee dabiiciga ah:

1. Ka qayb qaadashada wareegga ah ee walxaha.

2. Doorka xoolaha ee dabiiciga ah iyo ku jira formation of carrada. Gaar ahaan muhiim yihiin xawayaanka - caarada, cayayaanka, molluscs iyo earthworms. Taasi waa meesha aad u badan oo ciid-xawayaanka, horumarsan lakabka Dhirta dhulka.

3., Kaalinta saddexaad oo aan ka yarayn muhiim ah in burburinta xoolaha ma aha filan tijaabooyinka, dhirta macne iyo buka. Sidaas, xayawaanka caawiyo si ay u fuliyaan doorashada dabiiciga ah, oon ku dayactirka iyo hagaajinta koboca dhirta ka, hi ay horumar. Doorka kale waxa lagu ciyaaray by xayawaanka dulinka iyo ugaadhsiga dalka ee la xiriirta nuujiya herbivorous.

4. Control dadweynaha. Baadiyaha iyo xoolaha ugaadhsiga xakameeyo taranka ee herbivorous. Haddii kale, dhawr sano ee la soo dhaafay si buuxda u baabbi'in kari waayay qaar ka mid ah dhirta. Gaar ahaan muhiim yihiin shimbiraha insectivorous (qiimaha shimbiraha ee dabiiciga ah waa ku weyn yahay, waayo, iyagu la xakameeyo kororka xad-dhaafka ah ee cayayaanka iyo xayawaanka kale), Haad baana, toads Iyo xataa rahyo, mulacyada, fiidmeerta, umado, kuwa lamid ah dhulka, Qudhaanjadu, xoonka, iyo kooxaha kale ee xawayaanka iyo vertebrates.

5. Cross-pollination of dhowaad dhammaan noocyada kala duwan ee angiosperms, faafin abuurka ah ee ku xoortay geedihii iyo geedo. pollination The ka qayb tobanaan kun oo bees ku nool savannas, lamadegaanka, deel, seeraha Alpine. Xataa ee waqooyiga Greenland ayaa dadka ka mid ah bumblebees. In doorka raratada miraha geedaha, cows iyo ku xoortay geedihii guushu vertebrates sare - shimbiraha granivorous oo carnivorous, jiirka iyo xayawaanka naasalayda.

Ku dhawaad dadka oo dhan u matalaan dunida xoolaha ee foomka of shimbiraha waaweyn iyo Naasley, xamaarato iyo masaska. Savannah in aragtida ah dad badan oo maroodiga lala iyo libaaxyo, Soo bixitaanka iyo midii, gorayada, iyo gorgorraduna, kaymaha kulaylaha - orangutans iyo Saayiq, shabeelka iyo constrictors Boa, qurux shimbiraha Jannada, iyadoo taiga ah - capercaillie, yeey oo orso, deerada iyo bakeylaha. Laakiin ma aha oo dhan nuujiya hababka dabiiciga ah ka ciyaaraan door weyn. cunidda Dhirta, formation ciidda, pollination dhirta waxaa la siiyaa xawayaanka xayawaan. Centipedes, caarada, gooryaan, cayayaan, iwm Tan waxa u sabab ay tiro weyn oo kala duwan oo gaar ah. Doorka xoolaha ee dabiiciga ah, dabcan, sare. Iyo hawsha aadanaha waa in loo ilaalin lahaa oo dhan noocyada iyo dheelitirka dabiiciga ah.
