Ua raws li qhov xav tau, Hydrosere thiab Xerosere yog dab tsi?
Hydrosere yog ib qho kev cog qoob loo nyob rau hauv uas qhib dej tshiab ib txwm qhuav tawm, tsis tu ncua los ua swamp, marsh, thiab lwm yam thiab hauv hav zoov kawg. Xeroser yog kev vam meej ntawm cov zej zog ib puag ncig uas tshwm sim hauv thaj chaw qhuav qhuav xws li cov suab puam xuab zeb, xuab zeb dunes, ntsev suab puam lossis pob zeb suab puam.
Dab tsi yog 4 theem ntawm lub pas dej ua ke? Teb Cov Kws Paub Tseeb. Cov plaub theem ntawm lub pas dej ua ke yog pas dej pioneers, submergent nroj tsuag tshwm nyob ib ncig ntawm lub pas dej , decaying teeb meem raising thepond pem teb thiab ib tug marsh raug tsim. Lub pas dej yog cov qhov ntiav uas cov dej sau. Lawv yog tsim los ntawm geological txheej xwm.
Sib piv, Hydrarch succession yog dab tsi?
Hydrarch Succession . Hydrarch : Tsob ntoo kev vam meej pib ntawm cov dej ntiav, xws li cov pas dej thiab pas dej, thiab ua rau hauv hav zoov uas paub tab.
Tus txheej txheem ntawm kev ua tiav yog dab tsi?
Ecological kev vam meej yog cov txheej txheem ntawm kev hloov hauv cov qauv qauv ntawm ib lub zej zog ecological dhau sijhawm. Nws yog phenomenon los yog txheej txheem los ntawm qhov uas cov zej zog ecological tau dhau los ua ntau dua lossis tsawg dua thiab kev hloov pauv tau tshwm sim tom qab muaj kev cuam tshuam los yog thawj zaug colonization ntawm qhov chaw nyob tshiab.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
