Cov neeg siv khoom tseem ceeb tsuas tau ib feem ntawm tag nrho cov hnub ci zog -li 10% - ntes los ntawm cov neeg tsim khoom lawv noj. Lwm 90% yog siv los ntawm cov neeg tsim khoom rau kev loj hlob, kev loj hlob, thiab kev muaj sia nyob, los yog nws poob li cua sov. Koj ua tau tej zaum pom qhov no mus qhov twg.
Tsis tas li ntawd, cov neeg siv khoom qib siab siv zog npaum li cas?
Yog li ntawd, thawj cov neeg siv khoom tau txog 10% ntawm cov zog tsim los ntawm autotrophs, thaum theem nrab cov neeg siv khoom tau 1% thiab tertiary cov neeg siv khoom tau 0.1%. Qhov no txhais tau tias sab saum toj neeg siv khoom ntawm cov saw khoom noj tau txais tsawg kawg nkaus zog , raws li ntau ntawm cov khoom noj khoom haus zog tau poob ntawm qib trophic.
Kuj Paub, theem twg ntawm cov neeg siv khoom yog dais? Qee cov kab mob 'txoj hauj lwm hauv cov saw zaub mov tuaj yeem sib txawv raws li lawv cov khoom noj sib txawv. Piv txwv li, thaum a dais noj berries, lub dais ua haujlwm raws li qhov tseem ceeb neeg siv khoom . Thaum a dais noj cov nroj tsuag noj nas, cov dais ua hauj lwm raws li ib tug thib ob neeg siv khoom.
Raws li, tus neeg siv khoom qib 1 yog dab tsi?
Ua ntej - qib , (primary), Cov neeg siv khoom Lawv noj cov kab mob uas ua rau lawv tus kheej cov zaub mov los ntawm photosynthesis, raws li koj tam sim no twb paub lawm, lawv muaj xws li algae, nroj tsuag, thiab kab mob. Lawv yog ua ntej - cov neeg siv khoom qib vim lawv noj cov neeg tsim khoom, (nroj tsuag, kab mob, algae,), thiab yog herbivores lossis omnivores.
Lub zog ntau npaum li cas cov decomposers tau txais?
Decomposers , uas suav nrog cov kab mob, fungi, pwm, worms, thiab kab, rhuav tshem cov khib nyiab thiab cov kab mob tuag thiab rov qab cov khoom noj rau hauv av. Qhov nruab nrab kwv yees li 10 feem pua ntawm net zog kev tsim khoom ntawm ib qib trophic yog dhau mus rau qib tom ntej.

Nyob rau theem twg ntawm kev muag khoom tus neeg muag khoom feem ntau yuav ntsib tus neeg siv khoom thawj zaug?
Prospecting yog thawj kauj ruam hauv kev muag khoom, uas muaj kev txheeb xyuas cov neeg siv khoom muaj peev xwm, aka kev cia siab. Lub hom phiaj ntawm kev cia siab yog los tsim cov ntaub ntawv ntawm cov neeg siv khoom zoo thiab tom qab ntawd sib txuas lus nrog lawv hauv kev cia siab ntawm kev hloov pauv lawv los ntawm cov neeg muaj peev xwm mus rau cov neeg siv khoom tam sim no
Qhov twg yog ib qho piv txwv ntawm cov neeg siv khoom thawj qib lossis thawj tus neeg siv khoom?
Cov neeg siv khoom tseem ceeb cuam tshuam nrog cov neeg tsim khoom thiab cov neeg siv khoom thib ob. Lawv tuaj yeem cuam tshuam nrog cov decomposers, txawm tias feem ntau lawv yuav cuam tshuam nrog cov neeg tsim khoom / cov neeg siv khoom thib ob. Kab laum paj rwb, nas teb, kab nyom, thiab tus ntoo ntsaum yog tag nrho cov piv txwv ntawm cov neeg siv khoom thawj qib
Dab tsi yog qhov txawv ntawm cov neeg siv khoom thiab cov neeg siv khoom?
Cov neeg siv khoom - peb tab tom tham txog ib tus neeg siv khoom thiab ib yam dab tsi uas yog lawv: tus neeg siv lub kaus mom, tus neeg siv khoom thov, tus neeg siv khoom cov nyiaj. Cov neeg siv khoom ' - peb tab tom tham txog ntau tus neeg siv khoom thiab qee yam uas yog lawv: cov neeg siv khoom lub kaus mom, cov neeg siv khoom thov, thiab cov neeg siv khoom cov nyiaj
Nws hu li cas thaum cov khoom tshiab lossis cov saw tshiab nyiag cov neeg siv khoom thiab muag los ntawm cov laus uas twb muaj lawm nws raug xa mus rau?

Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
