Crustaceans, piv txwv li, zais cov hlau nplaum uas muaj hlau nplaum (8 mus rau 12 feem pua magnesium) tab sis nthuav tawm cov lus teb zoo dua rau cov pa roj carbon dioxide siab dua li lwm cov kab mob tshawb nrhiav, suav nrog cov uas tsis tshua muaj magnesium calcite, zoo li oysters, bay scallops thiab periwinkles.
Cov kab mob dab tsi muaj calcite?
Lub plhaub thiab pob txha pob txha ntawm ntau cov kab mob marine yog tsim los ntawm calcite lossis aragonite - ob hom ntxhia ntawm calcium carbonate. Cov kws tshawb fawb tshwj xeeb yog xav paub txog aragonite, uas yog tsim los ntawm ntau yam tropical corals, dej txias corals, pteropods thiab qee cov molluscs. Nws yog soluble ntau dua li calcite.
Dab tsi tsiaj secretes calcium carbonate?
Marine biogenic calcification yog txheej txheem los ntawm cov kab mob hauv hiav txwv xws li oysters thiab clams daim ntawv calcium carbonate. Cov dej hiav txwv yog tag nrho ntawm cov tshuaj yaj, ions thiab cov as-ham uas cov kab mob tuaj yeem siv rau lub zog thiab, nyob rau hauv cov ntaub ntawv ntawm calcification, los tsim cov plhaub thiab cov txheej txheem sab nrauv.
Puas yog calcium carbonate ua los ntawm cov ntses?
Shellfish yog cov tsiaj uas tsim calcium carbonate shellsthiab pob txha, xws li mussels, oysters thiab corals. Lawv tsim lawv lub plhaub tiv thaiv los ntawm cov txheej txheem hu ua biomineralisation - tsim cov zaub mov tawv xws li calcium carbonate los ntawm lim calcium thiab carbonate los ntawm dej.
Ib yam kab mob calcifying yog dab tsi?
Cov kab mob sib xyaw calcium thiab carbonate los ua cov tawv tawv thiab pob txha tawm ntawm cov ntxhia calcium carbonate calcium carbonate 3. Yog li ntawd, cov nroj tsuag thiab tsiaj txhu uas siv calcium carbonate rau cov qauv thiab kev tiv thaiv. hu ua calcifying organisms calcifying organisms 3.
