Meaning of ulwelwe ngokwemvelo. Yini ubumqoka hlobo onsundu, oluhlaza futhi abomvu ulwelwe

Ulwelwe iqembu ubanzi kakhulu futhi ezihlukahlukene zezitshalo aphansi. Ngaphezu kwalokho, kukhona eziningi kakhulu kule planethi photosynthesis eziphilayo, okuyizinto ezibalulekile kakhulu isimo sethu. Ulwelwe zingatholakala kuyo yonke indawo. La magciwane bahlala izilwandle amanzi aqabulayo nezilwandle kanye namagxolo nomhlabathi usemanzi.

ngezigaba

Kuze kube manje, isayensi iye yenza kwaba eyabekwa phezu eziyikhulu zinhlobo ezehlukene ulwelwe. Nazo ngokufanayo, zihlukaniswe amaqembu ayishumi, kuye ngokuthi umbala uhlamvu:

- oluhlaza;

- igolide;

- pirofitovye;

- ophuzi;

- diatoms;

- brown;

- abomvu;

- oluhlaza;

- euglenophytes;

- Stoneworts.

Inani Biogeocenoses

Ulwelwe e i osebenzelana aqueous kukhona abakhiqizi main izinto eziningi eziphilayo. Bona ngqo hhayi kuphela, kodwa futhi ngokungaqondile, luwumthombo oyinhloko okunomsoco for bonke amadamu isilwane. Akwaziwa ematsheni (oluthambile, diatomite namathempeli ngokhonkolo namatshe), ezavela izigaba Geological esidlule ngenxa ngibone umjikelezo wokuphila kwe la magciwane photosynthesis.

Indima ngokwemvelo

Ukuze ukuphila kule planethi yethu, nezitshalo zasolwandle zimane kunesidingo. Okokuqala, ukubaluleka ulwelwe emvelweni ngenxa yokuthi ukuthi zingabantu ukudla eminingi engokwemvelo. Lezi zitshalo ukondla ezinamagobolondo futhi molluscs, sea urchin zidla, inhlanzi, njll

Omkhulu ukubaluleka zasolwandle ngokwemvelo futhi deku-mpilo kumiswa. akhawunti bona phakathi amathathu mahlanu amaphesenti yalolu ketshezi oluyigugu ukuthi ikhishwe nezilwane kule planethi yethu.

Ulwelwe, kanye nezimila eliwumhlaba, khulula emoyeni kusukela inkinga ka isamba ngokweqile carbon dioxide. Ngezinye izikhathi ziba ziningi kakhulu ukuthi amanzi liba ezihlukahlukene imibala.

Ulwelwe ngokuphelele bazivumelanisa nezimo ezihlukahlukene kakhulu. Lezi zitshalo bangaphila amanzi emvula, lapho inani usawoti incane. Izindawo zawo zokuhlala kukhona evele ezinamadwala ashisayo, namanzi alpine izinguzunga zeqhwa. Ulwelwe kungatholakala phezulu inhlabathi izingqimba, okuyinto kalula zingene elangeni. Lezi zitshalo bayakwazi ikoloni ezinamadwala ezingaphili inhlabathi substrates. Meaning of ulwelwe ngokwesimo bands ezifana likhulu kakhulu. Lezi zitshalo esiyingqayizivele ukudala izimo ukuqinisekisa ukuthi inhlabathi yase evundile.

Okusho zasolwandle ngokwemvelo futhi ukujikeleza enkulu izinto. Ngokuyinhloko zidla ezinamagobolondo, okuyinto kamuva sidliwe izinhlanzi.

obomvu ulwelwe

Cishe bonke abamele lezi zitshalo atholakala kwezilwandle. ulwelwe Red abe obuphelele abalulekile, ongafinyelela ngamamitha amabili. Ngaphezu chlorophyll e abamele lezi zinhlobo nezitshalo zasolwandle kumaseli aqukethe ezihlukahlukene zemibala. umbala wabo sithinta umbala ulwelwe ngokwabo. Ngokuvamile, zombala anjalo ulwelwe abomvu. Nokho, lapho kungenzeka pink, bluish, nezinye imibala.

ulwelwe Red, olubizwa nangokuthi ama-whelk unomzimba ethambile nokuthi uyatetema. Esinemthombo yalezi izitshalo, kusukela okukhanyayo ukuba acishe black, kunikeza embusweni kwamanzi wobuhle engenakuqhathaniswa.

ngokoqobo

Inani ulwelwe obomvu likhulu kakhulu amathuba okuba indoda. Enye yalezi zinhlobo plant - chondrus, okuyinto uhlala eNorth Sea, - usetshenziswa njengesibonelo izidakamizwa ukuze kwelashwe izifo zemigudu yokuphefumula. It ezikhishwe obomvu ulwelwe agar, elisetshenziswa ibhizinisi confectionery. Whelk ezidingekayo futhi microbiologists. Ngo-laboratory, bajwayele ukuze bathole amasiko okumsulwa kwamagciwane.

wrack

Lolu hlobo izitshalo emanzini ezindaweni ezisogwini ingenye imithombo eyinhloko udaba eziphilayo. Lokhu kunjalo, ikakhulu sici for kwezilwandle polar nendawo ezizobekwa athokomele. Kulezi zindawo ulwelwe biomass per imitha square bengase bazikhandlele amashumi amaningana amakhilogramu.

Lezi ezihlabayo yakha kelp. Ukubaluleka kwala "ihlathi kolwandle" likhulu kakhulu. Ababona kuphela indawo yokuhlala, kodwa futhi ube yindawo amandla, kanye eziningi ezisogwini zizalela izilwane. Ngaphezu kwalokho, ulwelwe brown ukudala izimo ephelele ukusabalala zizalela endaweni yabo nezinye ulwelwe micro- futhi macroscopic.

izitshalo iyamangalisa umthombo emhlabeni kuphela ukukhiqizwa nosawoti of alginic acid - alginates. Le into uyakwazi ukuncela kuze kube ezingamakhulu amathathu amayunithi wesisindo okusamanzi, okuholela isixazululo viscous eyatholakala. Leli khono evumela ukusetshenziswa ulwelwe brown embonini yezokudla. Alginates zihlobene kubo, ukungezwa ayisikhilimu, isagcine kanye neziphuzo zezithelo. Ngaphezu kwalokho, imfuyo sithuthukisa izinga e ukunyathelisa izincwadi futhi ikhonza ukungadluliseli umbala izindwangu anemibala ukumelana.

Alginates ekhiqizwa kusuka ulwelwe ensundu, kudingeka ekukhiqizeni nezindwangu zokwenziwa kanye Plastics. Batinikela zokwakha nopende weatherproof. Futhi alginates asetshenziswa njengoba izinto zokusetshenziswa emsebenzini wokukhiqiza eliphezulu zokugcoba ngoba imishini, sutures encibilikayo kuhlinzwa, ayinhlama namafutha e kwamakha futhi eyenza imithi izimboni. Sekuyisikhathi eside ulwelwe brown zidliwa. Basuke ikakhulukazi ohlonishwayo ekuphekeni abantu lamazwe ase-Asia.

ulwelwe oluhlaza

Lolu hlobo amanzi isitshalo zisakazwa yonkana planethi yethu. Iningi ulwelwe green atholakala ngamanzi agobhozayo, kodwa kukhona futhi isamba esikhulu amafomu zasolwandle yabo. Kukhona ezinye izinhlobo zezitshalo ukuthi sebejwayele ukuba eliwumhlaba ukukhahlamezeka kwendawo kanye ekuphileni enhlabathini izingqimba. ulwelwe Green zingatholakala emadwaleni kanye amagxolo ezihlahla, nezinye izakhiwo. Izindawo ezinkulu eziseningizimu lezi zitshalo nengxenye 'izimbali "yamanzi, iqhwa, inhlabathi kanye namagxolo.

Inani elikhulu ulwelwe oluhlaza ngokwemvelo. Okokuqala, it is a umthombo womoya-mpilo. Indima ebalulekile lezi zitshalo ekwelapheni yabulala namachibi ezinhlanzi. Inani ulwelwe oluhlaza kunzima overestimate. Bona kabusha carbon dioxide futhi izakhi, iziphi ziyoncibilika emanzini, futhi zihilelekile synthesis izinto eziningi eziphilayo.

Okwamanje, abameleli flora zasemanzini kukhona imikhiqizo ehlukahlukene yokudla okunempilo. Futhi ukuzisebenzisa ngezinhloso zokwelapha. Of ikakhulukazi eluhlaza ulwelwe isehlane Izinto - hlorellin okuyinto suppresses ukusabalala emzimbeni eziningi namagciwane abangela izifo. Mina ngeke azinake lezi zitshalo kanye imithi yendabuko. Green ulwelwe filamentous uhlobo asetshenziselwa ubuhlungu ukulibopha.
