YBiome vs Ecosystem
Kev sib cais ntawm ecosystems thiab biomes yog ib qho teeb meem ntawm qhov chaw thiab lub sijhawm. Lub ecosystem uas muab rau yuav txawv nyob rau lub sij hawm, nrog ecological succession, kwj txav, drought, thiab extinction ntawm hom, qhia txog kab txawv, tib neeg cuam tshuam thiab lwm yam. Biomes raug txhais los ntawm cov ntawv tseem ceeb ntawm lub neej. Lawv sib npaug dynamic ntawm lub sij hawm ntev. Cov npoo ntawm biomes yuav txav nrog lub ntiaj teb ua kom sov lossis txias, hloov dej nag, kev txav ntawm cov dej khov, thiab nce dej hiav txwv thiab lwm yam. Tsis yog cov ecosystems lossis biomes tuaj yeem cim tau yooj yim ntawm daim ntawv qhia. Tsis tas li ntawd, lawv yuav tsis nyob twj ywm tsis hloov.
Ecosystem yog dab tsi?
Ib qho chaw ecosystem yog ib chav ua haujlwm lossis ib qho kev ua haujlwm hauv ib puag ncig uas muaj cov tshuaj abiotic lossis tsis muaj sia nyob thiab biotic lossis cov kab mob muaj sia cuam tshuam. Abiotic Cheebtsam muaj xws li av, dej, cua, lub teeb, kub, av noo thiab pH thiab lwm yam. Av muab anchorage rau tag nrho cov nroj tsuag. Tsis tas li ntawd, nws muab chaw nyob rau ntau yam kab mob. Cov dej yog xav tau los ntawm tag nrho cov kab mob, ua lawv cov dej num metabolic. Atmosphere muaj xws li carbon dioxide rau photosynthesis, oxygen rau ua pa thiab nitrogen rau nitrogen kho kab mob. Lub hnub ci muab lub zog rau tag nrho cov ecosystem uas twb muaj lawm. Tsis tas li ntawd, qhov ntsuas kub tsim nyog yog qhov tsim nyog rau txhua yam kev ua haujlwm metabolic. Cov kab mob muaj sia nyob muaj ib qho kev hierarchy nyob rau hauv ib qho ecosystem. Lawv yog cov thawj tsim, cov neeg siv khoom thiab cov decomposers. Cov kab mob muaj sia cuam tshuam nrog ib leeg tsim cov khoom noj khoom haus hauv ib qho ecosystem. Cov khoom noj khoom haus sib txuas ntawm qee qhov chaw tsim cov webs nyuaj. Nyob rau hauv ib qho ecosystem, cov khoom noj webs no ua rau muaj kev cuam tshuam ntawm ecosystem; ntau complex cov zaub mov webs yog, cov ecosystems nyob ruaj khov. Cov khoom tsis muaj sia kuj xav tau los ntawm ib qho ecosystem. Txhua yam ntaub ntawv uas yuav tsum tau muaj los ntawm kab mob yog tau los ntawm ib puag ncig. Decomposers ua lub luag haujlwm tseem ceeb hauv kev caij tsheb kauj vab. Lub hauv paus tseem ceeb ntawm lub zog hauv ecosystem yog hnub ci hluav taws xob. Lub zog tsis yog cycled, thiab nws txav unidirectionally. Lub ntiaj teb ecosystems tuaj yeem muab cais ua ob pawg. Cov no yog cov ecosystems hauv av thiab cov dej ecosystems.
YBiome yog dab tsi?
Nws yog ib cheeb tsam ntawm lub ntiaj teb txiav txim siab los ntawm cov huab cua loj thiab cov yam ntxwv ntawm cov nroj tsuag. Biomes yog kev tswj hwm huab cua sib sau ua ke ntawm cov kab mob. Nws yog qhov loj tshaj plaws geographical biotic chav tsev. Biomes feem ntau muaj npe tom qab hom tseem ceeb ntawm lub neej. Piv txwv li, hauv hav zoov hav zoov hav zoov, nyom nyom, lossis coral reef, cov ntaub ntawv tseem ceeb ntawm lub neej feem ntau yog cov nroj tsuag lossis corals. Ib qho biome tuaj yeem sib faib thoob plaws ntiaj teb. Vim muaj cov qauv zoo sib xws ntawm kev xaiv ntuj, hom nyob hauv ntau qhov chaw ntawm biome tej zaum yuav zoo sib xws hauv lawv cov tsos thiab kev coj cwj pwm. Muaj yim biomes loj. Cov no yog tundra, taiga, temperate (deciduous) hav zoov, temperate evergreen, tropical rain forests, grassland, deserts or tropical deciduous forests. Piv txwv li, cov nyom biome yog cov yam ntxwv ntawm cov nyom thiab lwm hom tsiaj. Nyob rau hauv no biome, tag nrho cov nroj tsuag yog yoog mus rau ceev ceev, tawg hluav taws, uas hlawv saum cov nroj tsuag.
Qhov txawv ntawm Biome thiab Ecosystem yog dab tsi?
• Ib qho ecosystem tuaj yeem loj lossis me. Ob lub ecosystem zoo sib xws raug suav tias yog "ob lub ecosystems zoo sib xws" es tsis yog "ib lub ecosystem" tshwj tsis yog thaj av nyob nruab nrab ntawm lawv kuj suav nrog.
• Hauv qhov sib piv, lo lus biome yog siv rau qhov pom kev zoo sib xws tab sis tsis tas yuav tsum txuas nrog thaj chaw.
• Ib qho ecosystem feem ntau me me thaum piv rau qhov loj ntawm biome vim tsis zoo li lub ecosystem ib biome tej zaum yuav raug faib thoob plaws ntiaj teb.
