Nws tshwm sim li cas. Cov ua ntej ob peb hom rau colonize kev ntxhov siab cheeb tsam hu ua pioneer hom. Nyob rau hauv thawj succession, pioneer hom yuav tsum kab mob uas tuaj yeem nyob ntawm pob zeb liab qab. Lawv feem ntau suav nrog cov kab mob thiab lichens (saib daim duab hauv qab).
Ua li no, thawj pawg kab mob dab tsi los ua kom thaj chaw hu ua?
Thawj hom kom colonize ib ecosystem hu ua pioneer hom.
Tsis tas li ntawd, cov kab mob dab tsi uas feem ntau yog thawj zaug ua kom thaj chaw tom qab muaj kev cuam tshuam? Thawj hom kom colonize ib cheeb tsam tom qab muaj kev cuam tshuam loj yog hu ua pioneer hom ; lawv pab tsim ib puag ncig tshiab. Kev vam meej thib ob tshwm sim tom qab muaj kev cuam tshuam xws li hluav taws kub hav zoov, qhov twg tseem muaj qee yam organic teeb meem tso cai tshiab nroj tsuag loj hlob.
Yog li ntawd, dab tsi yog lub npe muab rau cov kab mob uas 1st colonize ib cheeb tsam nyob rau hauv thawj succession?
Thawj kab mob tshwm sim nyob rau hauv cov cheeb tsam ntawm thawj succession feem ntau yog mosses los yog lichens . Cov kab mob no hu ua pioneer hom vim lawv yog thawj tug hom tam sim no; tus tho kev hom yuav tsum hardy thiab muaj zog, ib yam li tib neeg pioneers.
Yog vim li cas thawj succession yuav siv sij hawm ntev?
Piav: Secondary kev vam meej feem ntau tshwm sim sai dua thawj txoj kev vam meej vim lub substrate twb muaj lawm. Hauv thawj txoj kev vam meej , tsis muaj av thiab nws yuav tsum tau tsim. Cov txheej txheem no yuav siv sij hawm, raws li cov pioneer hom yuav tsum colonize cheeb tsam, lawv yuav tsum tuag, thiab raws li qhov no tshwm sim ntau zaus, av cov ntaub ntawv.

Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Cov ntaub ntawv dab tsi yog siv los faib cov kab mob mus rau hauv cov thawj thiab lub nceeg vaj?
Cell qauv yog siv los faib cov kab mob mus rau hauv Domains thiab Kingdoms. - Cov qauv ntawm tes siv li cas los faib cov kab mob mus rau hauv pawg taxonomic? Cov kab mob tuaj yeem raug cais thiab muab tso rau hauv Domains los ntawm lawv cov yam ntxwv
Dab tsi yog qhov tseeb ntawm thaj chaw saum npoo rau qhov sib piv ntawm cov kab mob nyob?
Raws li qhov loj ntawm lub cev nce, nws thaj chaw saum npoo mus rau qhov sib piv qis. Qhov no txhais tau hais tias nws muaj qhov tsawg dua qhov chaw muaj rau cov khoom sib txawv, yog li tus nqi ntawm diffusion yuav tsis nrawm txaus kom tau raws li nws cov kev xav tau ntawm cov hlwb
