Dhau li ntawm no, lub tswvyim ntawm biosphere yog dab tsi?
Los ntawm feem ntau ntawm biophysiological txhais , cov biosphere yog lub ntiaj teb ecological system integrating tag nrho cov ciaj sia thiab lawv cov kev sib raug zoo, nrog rau lawv kev sib raug zoo nrog lub ntsiab ntawm lithosphere, geosphere, hydrosphere, thiab cua.
Dab tsi yog biosphere thiab nws cov khoom?
Biosphere -Txhua tus nyob cov khoom ntawm lub ntiaj teb. Tus qauv ntawm Biosphere muaj peb cov khoom : Abiotic, Biotic thiab lub zog cov khoom . I. Abiotic Cheebtsam : Nws muaj tag nrho cov tsis muaj sia nyob uas yog qhov tseem ceeb rau kev ciaj sia ntawm txhua yam muaj sia nyob. Nws muaj lithosphere, huab cua thiab hydrosphere.
