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).
