Khoom noj khoom haus yog ib yam dab tsi uas tsis muaj kab mob muaj sia tuaj yeem nyob thiab txhim kho. Nroj tsuag yog cov muaj sia nyob uas tuaj yeem tsim khoom noj rau lawv tus kheej los ntawm yuav luag tsis muaj dab tsi. Lwm tus pub rau yam tau tsim yam tsis muaj kev koom tes.

khoom noj khoom haus yog dab tsi?

Lub biosphere yog qhov loj thiab ntau yam. Nws suav nrog ntau yam tsiaj txhu. Ob leeg zoo nkauj thiab txaus ntshai. Tab sis tag nrho cov tsiaj no tau txuas nrog ib leeg. Qee lub sij hawm cov kev sib txuas no yog imperceptible, thiab qee zaum muaj lwm tus nyob ntawm ib hom. Qhov pom tseeb tshaj plaws kev sib txuas ntawm cov tsiaj muaj sia yog zaub mov. Cov khoom noj khoom haus tseem hu ua trophic.

Nroj tsuag yog cov tsiaj uas muaj peev xwm ntawm photosynthesis. Qhov no txhais tau hais tias yog muaj carbon dioxide, hnub thiab dej, lawv muaj peev xwm ciaj sia. Tsiaj txhu tsis muaj peev xwm li no. Yog li ntawd, feem ntau ntawm cov khoom noj chains pib nrog cov nroj tsuag.

Trophic chains txawv. Lawv muab faib ua ob pawg. Cov chains trophic uas pib nrog cov neeg tsim khoom hu ua pasture chains. Tab sis muaj cov uaspib nrog pov tseg. Piv txwv li, los ntawm cov tsiaj tuag. Cov chains no hu ua detrital.

Cov neeg tsim khoom, cov neeg siv khoom thiab cov khoom tawg yog qhov txawv ntawm cov kab mob nyob.

Producers

Ntau lub khw muag khoom noj pib nrog cov neeg tsim khoom. Qhov no yog lub npe ntawm tag nrho cov kab mob uas nws tus kheej tsim cov as-ham rau lawv tus kheej. Cov neeg tsim khoom nto moo tshaj plaws yog cov nroj tsuag ntsuab uas muaj peev xwm ntawm photosynthesis. Tab sis lawv kuj tuaj yeem suav nrog cov kab mob chemotrophic, uas tuaj yeem ua yam tsis muaj kev koom nrog lub hnub ci.

Cov neeg siv khoom

Tab sis tsis yog txhua tus neeg koom nrog hauv cov khoom noj khoom haus tuaj yeem tau txais yam tsawg kawg nkaus. Feem ntau xav tau lub neej yam uas tau tsim los ntawm lwm tus. Cov neeg siv khoom zoo li no hu ua cov neeg siv khoom. Tab sis txawm nyob hauv lawv, pab pawg ntawm ntau hom zaub mov tuaj yeem paub qhov txawv.

Qee tsiaj noj nroj tsuag. Lawv kuj nkag mus rau hauv cov saw zaub mov. Lawv qib trophic yog me ntsis siab dua cov nroj tsuag. Nyob rau hauv lem, lawv kuj yuav ua ib tug noj hmo.

Cov neeg xav tau nqaij noj yog hu ua predators. Qhov no yog qib tshiab. Lawv raug yuam mus yos hav zoov kom nrhiav zaub mov rau lawv tus kheej. Txhawm rau kom tau txais zaub mov, lawv yuav tsum siv tag nrho lawv cov tswv yim los taug qab thiab ntes tus tsiaj. Txhua tus tsiaj muaj tag nrho cov npe ntawm kev nyiam. Qhov no pab ntau hom kom muaj sia nyob txawm tias nyob rau lub sijhawm nyuaj tshaj plaws. Qhov no tseem ceeb heev tam sim no, vim hais tias ntau hom yog nyob rau verge ntawm extinction.

Decomposers

Cov khoom noj muaj xws li cov kab mob txawv txawv xws lidecomposers. Cov no yog cov muaj sia nyob uas hu ua "gravediggers of nature." Lawv pab pov tseg thiab corpses decompose rau hauv cov khoom yooj yim. Decomposers pub rau yam uas tsis muaj leej twg txaus siab rau.

Cua los yog pov tseg, tus decomposer pab kom decompose, hu ua detritus. Yog li ntawd, cov khoom noj khoom haus, uas pib nyob rau hauv xws li ib tug txawv txoj kev, yog detrital.

Muaj ntau tus decomposers sib txawv. Ntawm lawv yog cov kab mob, kab mob, saprophages, necrophages thiab coprophages.

Saprophages yog cov decomposers uas pub rau lub cev ntawm lwm yam tsiaj nyob. Necrophages kuj pub rau cov neeg tuag thiab carrion. Coprophages pub rau cov organic pov tseg ntawm cov tsiaj nyob. Tag nrho cov kab mob no pab khaws cov purity ntawm qhov, muab qhov chaw rau lub neej thiab kev loj hlob ntawm cov kab mob tshiab. Txawm hais tias qee tus xav txog cov tsiaj muaj sia uas qias neeg no, nws tsis tuaj yeem xav txog kev noj qab haus huv biosphere yam tsis muaj lawv.

Piv txwv ntawm cov khoom noj khoom haus

Nws tsis yooj yim rau kev kawm cov khoom noj khoom haus. Piv txwv yuav pab kom nkag siab tias leej twg pub rau leej twg. Feem ntau yog cov saw zaub mov pasture. Nws pib nrog ib tsob nroj. Yog li, koj tuaj yeem pib nrog cereals. Lawv muaj nyob rau hauv daim ntawv teev cov predilections ntawm hares. Hares yog cov neeg siv khoom ntawm thawj qhov kev txiav txim. hma noj hares. Hma yog cov neeg siv khoom thib ob.

Ntaus kuj nyiam cereals. Cov nas nyob hauv cov saw trophic no dhau los ua cov neeg siv khoom xaj thawj zaug. Qee lub sij hawm nas ua cov neeg raug tsim txom ntawm hedgehogs. Hedgehogs yog cov neeg siv khoom ntawm qhov kev txiav txim thib ob. Lawv kuj tsis tuaj yeem nyob ntsiag to rau lawv lub neej, vim yoglawv mus yos hav zoov. Cov tom kawg yuav dhau los ua cov neeg siv khoom thib peb.

Cov khoom noj khoom haus tuaj yeem pom hauv dej. Koj tuaj yeem pib nrog phytoplankton, uas tuaj yeem pub nws tus kheej ntawm nws tus kheej. Tab sis lawv noj zooplankton. Zooplankton yog cov khoom noj ntawm cov ntses me. Thiab lawv, nyob rau hauv lem, ua ib tug nyiam delicacy ntawm pike. Tab sis nws kuj tuaj yeem dhau los ua ib tus neeg noj.

Cov khoom noj uas ntev tshaj plaws tuaj yeem pom hauv dej hiav txwv. Nyob rau hauv xws li chains, muaj txawm cov neeg siv khoom ntawm qhov thib tsib thiab thib rau kev txiav txim. Txhua tus tuaj yeem tshawb fawb me ntsis. Qhov no nthuav heev thiab tso cai rau koj nkag siab zoo dua lub ntiaj teb nyob ib puag ncig koj.

Cov khoom noj khoom haus tsis zoo tsis suav nrog ntau tus neeg koom. Feem ntau lawv tsuas muaj pov tseg lossis ib lub cev tuag thiab ib tug tsiaj uas pub rau nws. Cov decomposers nto moo tshaj plaws yog cov kab mob thiab cov fungi.

Khoom noj khoom haus

Trophic chains tsis tuaj yeem cuam tshuam tag nrho lub neej ntawm biosphere. Tom qab tag nrho, yog tias peb xav tias tag nrho cov hares tau tuag lawm, hma thiab hma yuav tsis tuag. Lawv tsuas yog pub rau lwm tus tsiaj, txawm tias tus lej ntawm cov tsiaj txhu no yuav txo qis. Qhov kev tshuav ntawm ntuj yog khaws cia ua tsaug rau cov zaub mov webs.

Tseem yaj noj tau cov nroj tsuag sib txawv. Nws tuaj yeem noj cov nplej, oats, lichen, clover thiab lwm yam. Hma kuj tuaj yeem noj cov tsiaj sib txawv uas txawv ntawm ib leeg txawm tias loj. Cov khoom noj khoom haus thiab cov webs pab xwm sib npaug kom cov tsiaj muaj sia nyob tau yog tias muaj hom tsiajyuav ploj ntawm lub ntsej muag.

Cov khoom noj khoom haus muaj qee zaum nyuaj, tsis meej pem. Nws tsis yog ib qho yooj yim los txiav txim seb muaj pes tsawg tus tsiaj xav noj qee yam nroj tsuag thiab los ntawm cov tib neeg twg cov tsiaj me zais. Koj tuaj yeem sau ntau cov khoom noj sib txawv webs. Lawv yog cov nplua nuj nyob qhov twg muaj coob tus neeg nyob ib sab.

Lub ntiaj teb nyob ib puag ncig ib tus neeg khaws ntau yam tsis paub meej thiab lub sijhawm txaus nyiam. Ib tug ntawm lawv yog cov khoom noj khoom haus chains thiab networks. Nature cov khoom noj khoom haus ua tib zoo ua haujlwm pab ntau yam nroj tsuag thiab tsiaj txhu nyob hauv kev sib haum xeeb nrog ib leeg, nrhiav zaub mov rau lawv tus kheej thiab lawv cov tub ntxhais hluas, thiab ntxuav lawv cov chaw nyob ntawm qhov uas tau ua tiav nws lub neej muaj txiaj ntsig.
