Cov neeg tsim khoom yog tej yam ntsuab cog . Ntsuab nroj tsuag ua lawv cov zaub mov los ntawm kev tshav ntuj thiab siv lub zog los ua qab zib. Cov cog siv cov piam thaj no, tseem hu ua piam thaj los ua ntau yam, xws li ntoo, nplooj, keeb kwm, thiab tawv ntoo. Cov ntoo, xws li lawv muaj zog Oak, thiab yawg American Beech, yog piv txwv ntawm cov neeg tsim khoom.
Kuj paub yog, dab tsi yog qee qhov piv txwv ntawm cov tsim khoom?
Lichen Diatom American beech
Tom qab ntawd, lo lus nug yog, ob hom kev tsim khoom yog dab tsi? Muaj ob loj hom ntawm thawj cov neeg tsim khoom - phototrophs thiab chemotrophs. Phototrophs siv lub zog los ntawm lub hnub los hloov cov pa roj carbon dioxide rau hauv cov carbohydrates. Cov txheej txheem uas qhov no tshwm sim yog hu ua photosynthesis.
Hauv qhov no, 3 tus 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.
Dab tsi yog tus tsim khoom Vim li cas cov nroj tsuag hu ua cov tsim khoom?
Cov neeg tsim khoom . Nroj tsuag yog hu ua producers . Qhov no yog vim lawv tsim lawv tus kheej cov zaub mov! Lawv ua qhov no los ntawm kev siv lub teeb lub zog los ntawm lub hnub, carbon dioxide los ntawm huab cua thiab dej los ntawm cov av los tsim cov zaub mov - hauv daim ntawv ntawm qabzib / qab zib. Cov txheej txheem yog hu ua photosynthesis.

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)
Cov chaw tsim khoom noj khoom haus sib txawv yog dab tsi?
Cov Chaw Tsim Khoom Noj Khoom Noj muaj xws li: Tsev noj mov. Food Stands. Nqaij Markets. Tsev kawm ntawv noj su. Nursing Home Cafeterias. Cov Chaw Pabcuam Neeg Laus. Limited Food Stands. Khoom noj khoom haus ib ntus
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 qee qhov chaw ntawm cov ntaub ntawv uas tus neeg siv khoom siv tau thaum tshawb fawb txog cov khoom?
Hauv qab no yog tsib lub peev txheej uas koj tuaj yeem siv los ua kev tshawb nrhiav kev lag luam nrog cov ntsiab lus ntawm cov ntaub ntawv lawv muab. Census.gov. Cov ntaub ntawv suav pej xeem, uas Tsoom Fwv Teb Chaws Asmeskas khaws txhua kaum xyoo, muaj nyob rau hauv online, searchabledatabase. USA.gov. Koom Haum Lag Luam Me (SBA.gov) FocusGroup.com.
