Kev tsim khoom tseem ceeb yog ib lo lus siv los piav txog tus nqi ntawm cov nroj tsuag thiab lwm yam kab mob photosynthetic tsim khoom organic tebchaw nyob rau hauv ib tug ecosystem. Muaj ob yam ntawm thawj cov khoom lag luam : Tag nrho kev tsim khoom = tag nrho cov photosynthetic ntau lawm cov organic tebchaw nyob rau hauv ib tug ecosystem.
Kuj nug, dab tsi yog tsim nyob rau hauv thawj productivity quizlet?
thawj cov khoom lag luam . tus nqi ntawm kev tsim lub zog-nplua nuj organic tebchaw los ntawm cov ntaub ntawv inorganic. tag nrho thawj cov khoom lag luam . tag nrho cov khoom siv organic tsim tawm.
Kuj Paub, vim li cas cov khoom lag luam tseem ceeb tseem ceeb? Kev tsim khoom tseem ceeb yog qhov hloov dua siab tshiab ntawm lub hnub lub zog rau hauv cov khoom siv organic los ntawm photosynthesis. Kev tsim khoom tseem ceeb yog tseem ceeb vim nws yog cov txheej txheem uas tsim lub hauv paus ntawm cov zaub mov webs nyob rau hauv feem ntau ecosystems.
Nyob rau hauv txoj kev no, dab tsi yog qhov tseem ceeb ntawm kev tsim khoom hauv dej hiav txwv?
Kev tsim khoom tseem ceeb yog tus nqi uas atmospheric lossis aqueous carbon dioxide hloov los ntawm autotrophs ( thawj cov neeg tsim khoom) rau cov khoom siv organic. Kev tsim tawm thawj zaug ntawm photosynthesis yog txheej txheem tseem ceeb nyob rau hauv lub ecosystem, raws li cov producers tsim lub hauv paus ntawm tag nrho cov zaub mov web, ob qho tib si rau hauv av thiab nyob rau hauv lub ecosystem. dej hiav txwv.
Dab tsi yog qhov kev tsim khoom tseem ceeb hauv thaj chaw?
Cov thawj cov khoom lag luam ntawm ib lub zej zog yog tus nqi ntawm biomass tsim los ntawm photosynthesis ib chav tsev thiab lub sij hawm los ntawm cov nroj tsuag, lub thawj tsim tawm. Kev tsim khoom tseem ceeb feem ntau yog qhia nyob rau hauv units ntawm lub zog (piv txwv li, joules m -2 hnub -1) los yog nyob rau hauv units ntawm qhuav organic teeb meem (piv txwv li, kg m -2 xyoo -1).

Productivity nyob rau hauv qhov project tswj yog dab tsi?
Cov lus txhais no hais txog cov haujlwm uas yuav tsum tau ua, cov peev txheej tau mob siab rau txoj haujlwm ntawd, thiab lub sijhawm uas yuav siv zog ua haujlwm. Kev txhim kho kev tsim khoom tsim tau los ntawm kev muaj peev xwm ntawm tus thawj tswj hwm qhov project los tsim cov haujlwm loj tshaj plaws nrog cov peev txheej tsawg tshaj plaws hauv lub sijhawm luv tshaj plaws
Productivity nyob rau hauv human resource management yog dab tsi?
Productivity yog txhais raws li tus nqi ntawm cov khoom tau txais los ntawm ib chav tsev input ua hauj lwm nyob rau hauv daim ntawv ntawm kev ua hauj lwm, peev, khoom siv thiab lwm yam
Nyob rau hauv cov nroj tsuag twg photosynthesis tshwm sim nyob rau hauv qia es tsis nyob rau hauv nplooj?
1 Teb. Nyob rau hauv cov nroj tsuag photosynthesis tshwm sim nyob rau hauv chloroplasts. Chloroplast tuaj yeem nyob hauv lub hlwb ntawm cov txiv hmab txiv ntoo, stems, tab sis feem ntau ntawm tag nrho cov nplooj. Hauv qee qhov succulents (xws li cacti), lub ntsiab photosynthetic kev ua haujlwm yog txuam nrog lub qia
Yuav ua li cas yog productivity xam nyob rau hauv kev khiav hauj lwm tswj?
Productivity ntsuas seb cov peev txheej siv tau zoo npaum li cas. Nws yog xam raws li qhov sib piv ntawm cov khoom siv (cov khoom siv thiab cov kev pabcuam) rau cov khoom siv (kev ua haujlwm thiab cov khoom siv). Lub tuam txhab tsim khoom ntau dua, qhov zoo dua nws siv nws cov peev txheej. Productivity = tso zis / tawm tswv yim
