Yuav ua li cas yog ib tug tsim nyob rau hauv lub ecosystem

Yuav ua li cas yog ib qho ecosystem? Qhov no kev sib sau ntawm tag nrho cov nyob yam thiab qhov ib puag ncig. Ecosystem tshwm sim raws li ib tug unit, tag nrho cov interconnected nrog txhua lwm yam. Nyob rau hauv no tsab xov xwm peb xav txog qhov noj haus kev sib raug zoo, namely hais tias xws li producers, consuments, decomposers.

Cov zaub mov saw

Peb pib nrog lub tswvyim ntawm biogeocoenose. Qhov no kev sib raug zoo ntawm ntau hom ntawm tus kab mob no thiab lawv uas tsis yog-nyob ib puag ncig. Yog li ntawd, nyob rau hauv txhua biogeocoenose plaub mus:

• Abiotic yam. Cov no yog cov tag nrho cov ces tswg xwm, uas nyob rau hauv ib txoj kev cuam tshuam rau muaj sia nyob. Ib qho piv txwv yuav tsum teeb, kub thiab thiaj li nyob.
• Producers. Yuav ua li cas yog ib tug tsim? Qhov no yog feem ntau ib tug nroj tsuag. Lawv coj los ua ke organic tebchaw los ntawm inorganic, pawg no kuj muaj xws li ib co kab mob.
• Consuments (los yog nyob rau hauv lwm txoj kev - tau txais kev pab). Yog muaj tus kab mob uas pub nyob rau hauv tshuaj tsim los ntawm cov producers.
• Decomposers (qhov no fungi, protozoa, multicellular kab mob). Lawv nqa tej tuag organic tebchaw rau inorganic.

Yuav ua li cas yog ib tug tsim?

Raws li hais ua ntej lawm, yog muaj tus kab mob uas ua cov organic inorganic compound. Yuav ua li cas yog producers nyob rau hauv ib thiab qhov chaw lawv nyob? Peb pib nrog lub fact tias nws autotrophs, nroj tsuag ntsuab. Yuav ua li cas yog tus tsim ntawm cov khoom noj saw? Qhov no yog thawj txuas los ntawm nws tag nrho cov pib. Txawm cov zaub mov saw tej zaum koj yuav tuaj nrog, nws yeej ib txwm pib nrog cov nroj tsuag.

pas dej ecosystem

Xav txog lub pas dej ecosystem, namely lub biotic tivthaiv. Yuav ua li cas yog ib tug tsim nyob rau hauv lub ecosystem? Ntawm no lawv ua si lub luag hauj lwm ntawm algae, loj cov nroj tsuag thiab hauv qab muaj. Thaum cov kab mob ntau dej acquires ib tug ntsuab zas.

Tsis tas li ntawd faib thawj thiab tau txais kev pab. Cov yav tas los xws li lub kab pub rau cov nroj tsuag thiab lawv residues, xa mus rau lub thib ob txhom uas pub rau thawj tau txais kev pab tog twg los, los yog txhua lwm yam.

Peb inhabitants ntawm lub ecosystem - nws saprotrophs uas nyob qhov txhia chaw, tab sis tshwj xeeb tshaj yog txuam nrog yog cai nyob rau hauv qab ntawm ib tug nplua mais ntawm tuag kab mob, kev ntawm uas lawv koom.

laboratory ecosystem

Zaum tsim ib tug tshwj xeeb kuaj ecosystems nrog ib tug ntau tshawb kom ntxaws txog tag nrho cov tshwm sim. Ntawm cov hoob kawm, uas ploj lawm thiab bioekosistem, tab sis lawv yog zoo li ntawd hais tias tag nrho tshawb tag nrho cov kev nthuav dav yog tsis tau. Ib qho piv txwv ntawm xws li ib tug system yog ib tug kuaj thoob dej yug ntses.

Piv txwv ntawm cov khoom noj chains

Txawm peb yuav ecosystem (natural los sis kuaj) nws yog ib txwm tau mus ua cov zaub mov saw. Nyob rau hauv thiaj li yuav kom ua rau nws, koj yuav tsum paub dab tsi nws muaj peb mus rau tsib units. Piv txwv li, ib lub tsev khoom noj khoom haus saw ntawm peb hais: qhwv - luav - cov neeg. Los yog ib tug ntau saw: cov nroj tsuag - cov tshuaj tua kab - Qav - dav dawb hau. Tej yam ntxwv uas yuav tsum tau tsim loj.

Cov piv txwv muab saum toj no yog tsis tsuas tau. Cov no yog cov piv txwv ntawm pasture chains, tab sis muaj kuj expansions chains uas pib hais tias tuag kab mob thiab mus tsiaj me me.

Ncig ntawm tshuaj

Raws li twb tau hais, nyob rau hauv cov xwm txhua yam yog ntuj thiab txhua yam yog sib thooj,. Yog hais tias peb xyuas nyob rau hauv ntau yam tag nrho cov txheej txheem, peb nco ntsoov hais tias muaj yog ib tug vicious vajvoog, uas yog tsis yooj yim sua mus ua txhaum. Ntawm no yog ib qho piv txwv: producers ntawm inorganic tshuaj tsim ntawm organic hnub ci zog (cov hnub ci zog yog hloov dua siab tshiab rau hauv tshuaj zog). Cov organic tebchaw xav tau heterotrophic kab mob raws li qhov cleavage, uas ua rau tsim ntawm inorganic tebchaw thiab thiaj li nyob.

Lub ntiaj teb no yog lawm lub hav zoov ntawm peb ntiaj chaw yuav tsis tau, yog hais tias ib co caij disappears. Zog yeej tsis ploj kiag li, nws mus txog rau lwm lub xeev.
