Cov neeg tsim khoom yog 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 kab mob uas tsim tsis tau lawv cov zaub mov.
Hauv qhov no, 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.
Kuj Paub, lub cev twg yog tus neeg siv khoom tseem ceeb? tshuaj ntsuab
Ib yam li ntawd, lub cev twg yog tus tsim khoom hauv cov khoom noj khoom haus?
Thawj cov neeg tsim khoom yog autotrophs thiab feem ntau yog cov kab mob photosynthetic xws li nroj tsuag , algae, los yog cyanobacteria. Cov kab mob uas noj thawj cov neeg tsim khoom yog hu ua thawj cov neeg siv khoom. Cov neeg siv khoom tseem ceeb feem ntau yog cov tsiaj txhu, cov neeg noj zaub mov, txawm tias lawv yuav yog cov neeg noj algae lossis cov kab mob noj.
Dab tsi yog 10 tus qauv ntawm cov neeg tsim khoom?
Cov neeg tsim khoom yog txhua hom nroj tsuag ntsuab. Ntsuab nroj tsuag 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 cov piv txwv ntawm cov neeg tsim khoom.

Hom kev lag luam twg lub cev tsim cov khoom nws muag rau cov neeg siv khoom?
Cov khoom lag luam uas koj, cov neeg siv khoom, tuaj yeem yuav rau kev siv tus kheej. Cov tuam txhab muag khoom muag rau cov neeg siv khoom noj khoom haus yog koom nrog kev lag luam rau cov neeg siv khoom, tseem hu ua lag luam-rau-cov neeg siv khoom (B2C) kev lag luam. cov khoom siv lub cev siv los ntawm cov tuam txhab los tsim lwm yam khoom
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
Lub algorithm twg yog siv los nrhiav kev sib koom ua ke ntawm cov khoom uas tus neeg siv khoom tuaj yeem yuav ntawm lub khw muag khoom?
Association Rule Mining Txoj hauv kev zoo tshaj plaws los nrhiav cov qauv no yog Kev Tshawb Fawb Kev Lag Luam Kev Lag Luam, uas yog cov txheej txheem tseem ceeb siv los ntawm cov khw muag khoom loj xws li Amazon, Flipkart, thiab lwm yam los txheeb xyuas cov neeg yuav khoom los ntawm kev nrhiav kev sib koom ua ke ntawm cov khoom sib txawv uas cov neeg siv khoom tso rau hauv lawv "kev yuav khoom. pob tawb”
Dab tsi yog tus tsim khoom tseem ceeb hauv cov khoom noj khoom haus?
Cov neeg tsim khoom tseem ceeb (cov kab mob uas ua rau lawv tus kheej noj los ntawm lub hnub ci thiab / lossis tshuaj lom neeg los ntawm cov seavents sib sib zog nqus) yog lub hauv paus ntawm txhua cov khoom noj - cov kab mob no hu ua autotrophs. Cov neeg siv khoom tseem ceeb yog cov tsiaj uas noj thawj cov neeg tsim khoom; lawv tseem hu ua herbivores (nroog noj)
Puas yog owl yog tus tsim khoom lossis tus neeg siv khoom?
Barn owls noj tsuas yog nas, xws li voles, nas thiab nas. Cov tsiaj no yog cov neeg siv khoom thib ob. Lawv muab cov neeg siv khoom tseem ceeb, zoo li kab, nrog rau cov neeg tsim khoom xws li txiv hmab txiv ntoo, noob thiab lwm yam nroj tsuag. Cov neeg tsim khoom hauv lub barn owl cov khoom noj khoom haus nyob ntawm qhov chaw nyob
