Ob tug tseem ceeb tshaj plaws climatic yam rau ecosystems yog hnub ci thiab dej. Hnub ci yog tsim nyog rau cov nroj tsuag kom loj hlob, thiab muab lub zog kom sov lub ntiaj teb cua. Lub teeb siv tswj cov nroj tsuag loj hlob. Lub teeb lub sij hawm cuam tshuam cov nroj tsuag flowering thiab tsiaj / kab cwj pwm.
Tsis tas li ntawd, lub hnub tseem ceeb npaum li cas rau cov khoom noj ntawm lub ecosystem?
Cov Hnub powers cov txheej txheem tshuaj ntawm photosynthesis - yuav ua li cas cov nroj tsuag thiab cyanobacteria (uas ntev ua ntej cov nroj tsuag) tsim zaub mov rau lawv tus kheej - lub zog loj hlob. Cov autotrophs (cov kab mob uas tsim lawv tus kheej zaub mov lub zog) yog lub hauv paus ntawm txhua tus zaub mov chains thiab zaub mov webs ntawm lub ntiaj teb.
Tsis tas li ntawd, lub hnub ci pab cov nroj tsuag loj hlob li cas? Lub hnub pab cov nroj tsuag loj hlob los ntawm kev muab lub zog rau cov txheej txheem ntawm photosynthesis tshwm sim. Photosynthesis yog txoj kev nroj tsuag hloov cov peev txheej inorganic, xws li hnub ci , dej, carbon dioxide, thiab minerals, rau hauv cov khoom siv organic uas cov cog siv tau.
Kuj tseem paub yog, yuav ua li cas lub ecosystem raug kev txom nyem yam tsis muaj hnub?
Ib ecosystem yuav ciaj sia mus ib txhis tsis muaj hnub ci , nws tsuas yog xav tau lub zog. Rau cov tsiaj hiav txwv nyob hauv dej hiav txwv tob heev, volcanoes yog lub hauv paus ntawm lub zog, tsis yog hnub ci . Koj ecosystems tuaj yeem siv sijhawm 100 hnub hibernation thaum hmo ntuj, zoo li lub caij ntuj no hauv ntiaj teb.
Puas yog Sun yog tus tsim khoom?
Cov hnub tsis yog a tus tsim tawm , tab sis yog siv ncaj qha los ntawm cov neeg tsim khoom . Cov hnub yog lub hauv paus ntawm lub zog uas txhua yam muaj sia nyob yuav tsum muaj sia nyob.

Yam khoom twg feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim?
Pawg (1) feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim. Cov hnub qub tsim nyob rau hauv cov cheeb tsam ntawm qhov ntom ntom hauv thaj tsam interstellar. Cov cheeb tsam no yog hu ua molecular huab thiab muaj feem ntau ntawm hydrogen. Helium, nrog rau lwm cov ntsiab lus, kuj pom nyob rau hauv cheeb tsam no
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
