Cladonia perforata
Ntxiv mus, 3 yam piv txwv ntawm tus tsim khoom yog dab tsi?
Piv txwv ntawm cov neeg tsim khoom suav nrog nroj tsuag ntawm txhua hom (nrog qee qhov kev zam raws li kab mob parasitic nroj tsuag ), cyanobacteria thiab phytoplankton. Cov neeg siv khoom yog cov kab mob uas pub rau cov neeg tsim khoom vim lawv tsis muaj peev xwm tsim lawv tus kheej cov carbohydrates. Lawv muab faib ua peb pawg: thawj, theem nrab thiab theem nrab cov neeg siv khoom.
Ib tug kuj yuav nug, 5 piv txwv ntawm cov neeg tsim khoom yog dab tsi? Qee qhov piv txwv ntawm cov neeg tsim khoom hauv cov zaub mov suav nrog ntsuab nroj tsuag , tsob ntoo me me, txiv hmab txiv ntoo, phytoplankton, thiab algae.
Ib yam li ntawd, nws yog nug, cov neeg tsim khoom muab piv txwv li cas?
Cov neeg tsim khoom yog txhua yam nroj tsuag ntsuab. Cov nroj tsuag ntsuab ua lawv cov zaub mov los ntawm kev tshav ntuj thiab siv lub zog los ua qab zib. Cov nroj tsuag siv cov suab thaj no, tseem hu ua qabzib los ua ntau yam, xws li ntoo, nplooj, cag, thiab tawv ntoo. Tsob ntoo, xws li lawv muaj zog Oak, thiab grand American Beech, yog piv txwv ntawm cov neeg tsim khoom.
Cov neeg tsim khoom yog dab tsi?
Cov neeg tsim khoom yog cov kab mob uas tsim zaub mov los ntawm cov teeb meem inorganic. Cov piv txwv zoo tshaj ntawm cov neeg tsim khoom yog cov nroj tsuag, lichens thiab algae, uas hloov dej, hnub ci thiab carbon dioxide rau hauv carbohydrates. Cov neeg siv khoom yog cov kab mob uas tsis tuaj yeem tsim lawv cov zaub mov.

Cov nqe lus ntawm tus nqi ntawm cov khoom tsim khoom yog dab tsi?
Tus Nqi ntawm Cov Khoom Tsim, tseem hu ua COGM, yog lo lus siv hauv kev tswj hwm nyiaj txiag uas hais txog lub sijhawm lossis nqe lus uas qhia tag nrho cov nqi tsim khoom. Nws tsis tsuas yog suav nrog tus nqi ntawm cov ntaub ntawv thiab kev ua haujlwm, tab sis kuj tseem muaj qhov sib txawv thiab txhim kho kev tsim cov nqi ua haujlwm
Dab tsi yog cov tswv yim thiab cov khoom tsim tawm hauv cov txheej txheem tsim khoom?
Hauv kev lag luam, yam tseem ceeb ntawm kev tsim khoom, peev txheej, lossis cov tswv yim yog qhov uas siv hauv cov txheej txheem tsim khoom los tsim cov khoom tawm - uas yog, cov khoom tiav thiab cov kev pabcuam. Tus nqi siv ntawm ntau yam inputs txiav txim seb qhov ntau npaum li cas ntawm cov zis raws li kev sib raug zoo hu ua ntau lawm muaj nuj nqi
Dab tsi yog qhov kev sib raug zoo ntawm tag nrho cov khoom tsim tau thiab cov khoom tsim tawm thawj zaug sau qhov sib npaug?
Koj tuaj yeem pom tias koj tus lej nyiaj hauv tuam txhab nyiaj tau txiav txim siab raws li hauv qab no: Koj qhov Net ntau lawm yog sib npaug rau koj qhov Kev Tsim Nyog Tag Nrho Tshem Tawm Tawm, uas yog tib yam li qhov sib npaug saum toj no uas hais txog Net Primary Production (NPP) = Gross Primary Production (GPP) Kev ua pa tawm (R)
Dab tsi yog qhov txawv ntawm cov neeg siv khoom thiab cov khoom tsim khoom?
Teb: Cov khoom siv yog cov khoom kawg rau kev noj cov neeg siv khoom kawg thaum cov khoom tsim khoom yog cov khoom siv raw rau lwm cov khoom lag luam. Teb: Cov neeg tsim khoom zoo yog ib qho siv los ntawm cov neeg tsim khoom: lub Hoobkas machinery, lub rooj ua haujlwm, cov ntaub ntawv raw thiab lwm yam
Dab tsi yog qhov txawv ntawm tus qauv tsim nqi ncaj ncees thiab tus qauv rov ntsuas dua?
Lwm yam tshaj tus nqi ncaj ncees tsis muaj depreciation whereas revaluation qauv muaj depreciation. Yog tias muaj qhov nce hauv tus qauv tus nqi ncaj ncees rau cov cuab yeej nqis peev, puas yog qhov txiaj ntsig tseem hu ua qhov nce ntawm kev txheeb xyuas uas yog tib yam rau tus qauv rov qab rau ppe???
