Qhov Tseem Ceeb - Saprophytes vs Parasites
Cov kab mob qhia ntau yam kev noj haus kom muaj sia nyob. Qee cov kab mob nyob ntawm lwm cov kab mob uas muaj sia nyob rau lawv cov khoom noj thaum lwm tus nyob ntawm cov khoom tuag. Saprophytes thiab parasites yog ob hom kab mob uas muaj ob hom kev tau txais kev noj haus. Qhov sib txawv tseem ceeb ntawm saprophytes thiab cab kab mob yog tias cov kab mob saprophytic tau txais cov khoom noj los ntawm cov neeg tuag thiab lwj cov organic teeb meem thaum cov kab mob cab ua kom tiav lawv cov khoom noj khoom haus los ntawm lwm cov kab mob nyob. Saprophytes raug suav hais tias yog ib feem tseem ceeb ntawm ecosystem vim tias lawv decompose cov ntaub ntawv organic tuag nyob hauv ib puag ncig thiab pab rov ua dua cov khoom noj.
Saprophytes yog dab tsi?
Qee cov kab mob nqus cov as-ham los ntawm cov nroj tsuag tuag thiab tsiaj cov ntaub ntawv nyob rau hauv ib puag ncig. Lawv hu ua saprophytes. Lawv secrete extracellular enzymes thiab degrade cov ntaub ntawv organic rau hauv cov tebchaw yooj yim. Yog li ntawd, lawv tseem ceeb heev rau kev tshem tawm lossis rov ua dua cov khoom tuag hauv ib puag ncig. Saprophytes ua lub luag haujlwm tseem ceeb hauv yuav luag txhua lub voj voog biogeochemical xws li nitrogen cycles, carbon cycles, hydrogen cycles, thiab mineral cycles.
Feem ntau hom fungal yog saprophytes. Lawv loj hlob ntawm cov ntaub ntawv organic tuag thiab nqus cov as-ham tsim nyog thaum decomposing nws. Qee cov nroj tsuag kuj yog saprophytes. Cov nroj tsuag no nyob rau ntawm cov nroj tsuag decaying thiab tsiaj residues thiab nqus cov as-ham yam tsis nqa tawm photosynthesis. Tseem muaj cov kab mob hauv av uas yog saprophytes.
Saprophytes ua raws li cov khoom siv rov ua dua tshiab ntawm ib puag ncig. Thaum lub sij hawm decomposition ntawm cov ntaub ntawv organic, ntau cov as-ham raug xa rov qab rau hauv av los ntawm saprophytes rau kev siv cov nroj tsuag thiab lwm yam kab mob nyob.

Pab yog dab tsi?
Qee cov kab mob nyob hauv lossis hauv lwm cov kab mob uas muaj sia nyob thiab tau txais cov khoom noj los ntawm lawv. Lawv hu ua parasites thiab cov kab mob uas muab cov as-ham yog lub npe hu ua cov kab mob. Parasites tsuas yog pub rau cov kab mob uas muaj sia nyob rau lawv cov khoom noj. Yog li ntawd, tus tswv tsev kab mob cuam tshuam los ntawm cov kab mob parasitic. Muaj cov kab mob cab thiab tsiaj txhu uas nyob ntawm lwm yam kab mob. Dodder nroj tsuag yog nrov li kab mob thiab lawv tsis muaj chlorophyll los ua photosynthesis. Cov nroj tsuag no cog rau ntawm lwm cov nroj tsuag thiab nqus cov as-ham los ntawm kev nkag mus rau hauv lawv cov stems ntawm suckers.
Ntau tus kab mob tib neeg yog tshwm sim los ntawm cov kab mob cab. Piv txwv li, Malaria yog tshwm sim los ntawm cov kab mob hu ua Plasmodium. Qee cov kab mob parasitic protozoans thiab helminths kuj ua rau mob plab hnyuv loj hauv tib neeg.

Summary – Saprophytes vs Parasites
Saprophytic kab mob nyob ntawm cov organic teeb meem tuag thiab ua tiav lawv cov khoom noj khoom haus los ntawm decomposing organic cov ntaub ntawv. Lawv suav hais tias yog thawj decomposers hauv ib puag ncig. Lawv pab nyob rau hauv yuav luag tag nrho cov as-ham los ntawm degrading complex organic cov ntaub ntawv rau hauv yooj yim tebchaw uas yuav nkag tau yooj yim absorbed los ntawm cov nroj tsuag thiab lwm yam kab mob nyob. Parasites yog cov kab mob uas nyob hauv lossis hauv lwm cov kab mob uas muaj sia nyob thiab tau txais cov khoom noj los ntawm lawv. Parasites tsis tuaj yeem ua rau lawv tus kheej cov zaub mov. Yog li ntawd, lawv pub cov tsiaj muaj sia nyob rau lawv cov khoom noj. Parasites tsis muaj txiaj ntsig vim lawv feem ntau ua mob rau lawv tus tswv thaum lub sijhawm pub mis. Parasites nyob ntawm tus tswv tsev rau kev ciaj sia. Yog li, qhov sib txawv tseem ceeb ntawm saprophytes thiab parasites yog txoj kev uas lawv ua tiav lawv cov khoom noj khoom haus.
