Qhov sib txawv tseem ceeb ntawm lub voj voog nitrogen thiab lub voj voog carbon yog tias lub voj voog nitrogen piav qhia txog kev hloov pauv ntawm nitrogen rau hauv ntau hom tshuaj thiab kev ncig ntawm huab cua, av thiab dej hiav txwv ecosystems thaum lub voj voog carbon piav qhia txog kev txav ntawm carbon thiab nws Ntau hom tshuaj nyob nruab nrab ntawm huab cua, dej hiav txwv, biosphere thiab geosphere.

Nyob rau hauv ib qho ecosystem, biochemical cycles yog ib qho tseem ceeb nyob rau hauv thiaj li yuav tswj lub ntuj sib npaug. Yog li ntawd, rau ntau lub ntsiab lus hauv ecosystem, peb tuaj yeem kos ib lub voj voog uas qhia txog kev txav ntawm lub caij los ntawm cov khoom sib txawv ntawm cov ecosystem. Nyob rau hauv lub voj voog, cov ntsiab lus tau hloov mus rau complex molecules thiab tom qab ntawd tawg nyob rau hauv decomposition rau yooj yim molecules. Txhua lub voj voog muaj lub pas dej loj dua, uas feem ntau yog abiotic. Nitrogen cycle, carbon cycle, phosphorus cycles thiab hydrological cycles yog qee qhov tseem ceeb ntawm biochemical cycles hauv xwm. Yog li ntawd, kev nkag siab txog kev caij tsheb kauj vab ntawm cov teeb meem thiab kev tswj xyuas kev caij tsheb kauj vab zoo yog qhov tseem ceeb kom txuag tau ib puag ncig los ntawm cov pa phem.

Nitrogen Cycle yog dab tsi?

Lub voj voog nitrogen yog ib qho tseem ceeb tshaj plaws ntawm cov voj voog geochemical tshwm sim hauv qhov xwm txheej. Nws piav qhia txog kev sib txawv ntawm cov tshuaj sib txawv ntawm nitrogen los ntawm huab cua, av thiab dej hiav txwv ecosystems. Lub ntsiab nitrogen reservoir yog huab cua. Nws muaj li ntawm 78% nitrogen gas, tab sis nws tsis tuaj yeem siv los ntawm ntau cov kab mob. Yog li nitrogen yuav tsum tau hloov mus rau cov ntaub ntawv uas tuaj yeem siv los ntawm cov nroj tsuag. Cov txheej txheem no hu ua nitrogen fixation.

Ntxiv mus, nitrogen fixation tshwm sim nyob rau hauv ntau txoj kev. Ib txoj hauv kev yog kev kho mob lom neeg. Cov kab mob symbiotic zoo li Rhizobium uas nyob hauv cov hauv paus nodules ntawm cov nroj tsuag leguminous tuaj yeem kho atmospheric nitrogen. Tsis tas li ntawd, muaj qee cov kab mob nyob dawb zoo li Azotobacter uas tuaj yeem kho nitrogen. Lwm txoj kev ntawm nitrogen fixation yog kev lag luam nitrogen fixation. Los ntawm cov txheej txheem Heber, cov roj nitrogen tuaj yeem hloov mus rau ammonia uas yog siv los ua chiv thiab tawg. Tsis tas li ntawd, ib txwm nitrogen hloov mus rau nitrate thaum xob laim.

Feem ntau cov nroj tsuag nyob ntawm kev muab cov nitrate los ntawm cov av rau lawv qhov xav tau nitrogen. Tsiaj txhu nyob ntawm cov nroj tsuag ncaj qha lossis ncaj qha kom tau txais lawv cov khoom noj nitrogen. Thaum cov nroj tsuag thiab tsiaj tuag, lawv cov tebchaw uas muaj nitrogen zoo li cov proteins rov qab los rau hauv nitrates los ntawm cov kab mob saprotrophic thiab fungi. Nws tshwm sim los ntawm cov tshuaj tiv thaiv oxidation uas cov protein hloov mus rau hauv cov amino acids thiab tom qab ntawd cov amino acids hloov mus rau ammonia. Raws li, cov txheej txheem yog 'nitrification', thiab Nitrosomonas thiab Nitrobacter yog ob kab mob koom nrog hauv qhov no. Nitrification tuaj yeem thim rov qab los ntawm cov kab mob denitrification. Lawv txo cov nitrate hauv cov av rau cov roj nitrogen thiab tso tawm rau hauv qhov chaw.

Carbon Cycle yog dab tsi?

Carbon cycle yog lwm lub voj voog geochemical uas qhia txog kev hloov pauv ntawm cov ntaub ntawv sib txawv ntawm cov pa roj carbon monoxide thiab kev ncig lawv los ntawm huab cua, hydrosphere, biosphere thiab geosphere. Cov pa roj carbon monoxide tseem ceeb rau cov kab mob muaj sia yog cov pa roj carbon dioxide tam sim no hauv cov cua lossis yaj hauv cov dej saum npoo av. Cov nroj tsuag photosynthetic, algae, thiab cov kab mob xiav-ntsuab tuaj yeem hloov cov pa roj carbon dioxide rau hauv cov khoom sib txuas xws li carbohydrates. Carbohydrates ua lub tsev thaiv rau feem ntau lwm cov organic tebchaw uas lawv xav tau, rau lawv cov qauv thiab kev ua haujlwm.

Tsiaj txhu tau carbon los ntawm cov nroj tsuag ncaj qha lossis tsis ncaj. Cov pa roj carbon dioxide absorbed los ntawm cov nroj tsuag rau photosynthesis yog counterbalanced los ntawm kev ua pa ntawm cov nroj tsuag thiab tsiaj txhu. Yog li ntawd, photosynthesis thiab ua pa yog lub ntsiab mechanisms uas ua rau kom lub ntuj tshuav nyiaj li cas ntawm cov pa roj carbon voj voog.

Ib yam li ntawd, qee cov pa roj carbon dioxide ruaj khov los ntawm photosynthesis yog khaws cia rau hauv lub cev ntawm cov kab mob muaj sia. Tom qab ntawd, thaum lawv tuag, cov pa roj carbon rov qab mus rau hauv av thiab dej hauv lub cev. Thaum cov teeb meem tuag no sau rau hauv av ntev dua, lawv hloov mus rau hauv fossil fuel deposits. Cov pa roj carbon dioxide rov qab los rau hauv cov huab cua thaum tib neeg hlawv roj fossil. Nyob rau hauv no txoj kev, cov pa roj carbon compounds circulate los ntawm txawv spheres.

Dab tsi yog qhov zoo sib xws ntawm Nitrogen Cycle thiab Carbon Cycle?
