Trophic Chains piv txwv thiab cov hauj lwm
Cov zaub mov - nws yog ib yam dab tsi tsis muaj uas yuav muaj tsis tau nyob thiab tsim ib tug tib sia. Nroj tsuag - cov no yog muaj sia nyob uas tau lawv tus kheej tsim rau lawv tus kheej ib tug noj mov los ntawm tsis muaj dab tsi. Lwm tus pub rau lub fact tias nws yog tsim tsis muaj lawv cov kev koom tes.
Yuav ua li cas yog lub trophic saw?
Nroj tsuag - yog creatures uas muaj peev xwm sawv ntawm photosynthesis. Qhov no txhais tau tias yog muaj cov pa roj carbon dioxide, hnub ci thiab dej, lawv muaj peev xwm ciaj sia. Tsiaj txhu rau ib tug tsis muaj peev xwm. Vim hais tias feem coob ntawm cov trophic saw pib nrog nroj tsuag.
Khoom noj khoom haus chains yog cov sib txawv. Lawv muab faib ua ob pawg. Cov khoom noj khoom haus saw, uas pib nrog ib tug tsim hu ua grazing. Tab sis muaj cov neeg uas pib nrog pov tseg. Piv txwv li, tsiaj carcasses. Cov chains yog hu ua detrital.
Cov uas muaj sia nyob paim producers, tau txais kev pab thiab decomposers.
producers
Muaj ntau ntawm cov khoom noj khoom haus saw pib nrog lub producers. Nws li ces thiaj li tau hu tag nrho cov neeg muaj tus kab mob uas ua ntawm nws tus kheej rau lawv tus kheej cov as-ham. Qhov tseem zoo-paub producers yog ntsuab nroj tsuag uas muaj peev xwm sawv ntawm photosynthesis. Tab sis kuj lawv yuav tsum tau ntaus nqi, thiab cov kab mob chemotroph uas yuav ua txawm tsis muaj tshav ntuj.
consuments
Tab sis tsis yog txhua txhua koom nyob rau hauv cov zaub mov chains yuav ua qhov tsawg kawg nkaus. Feem ntau cov yuav tsum ua raws li tau ua los ntawm lwm leej lwm tus. Cov tau txais kev pab raug hu los ntawm kev pab. Tab sis txawm nyob rau hauv lawv muaj yog ib tug txawv hom ntawm pawg zaub mov.
Cov neeg uas xav tau nqaij rau lub neej, yog hu ua npua. Qhov no tshiab. Lawv yuam kom mus rau tus plob hav zoov mus nrhiav tau lawv tus kheej cov khoom noj. Nyob rau hauv thiaj li yuav tau cov zaub mov, lawv yuav tsum siv tag nrho lawv tricks los teev cia thiab ntes prey. Txhua predator muaj ib tug ntev daim ntawv teev cov nyiam. Qhov no yuav pab ntau hom kom ciaj sia txawm nyob rau hauv lub feem ntau nyuaj lub sij hawm. Qhov no yog tshwj xeeb yog ib qho tseem ceeb vim hais tias muaj ntau yam hom nyob rau hauv lub brink ntawm extinction.
decomposers
Trophic saw thiab xws li tej yam txawv cov kab mob no li decomposers. Cov no yog cov uas muaj sia nyob beings, uas yog hu ua "qhov ntxa-diggers ntawm qhov." Lawv pab pov tseg thiab corpses decompose rau hauv yooj yim Cheebtsam. Decomposers pub rau ntawm qhov tseeb hais tias tsis muaj ib tug twg yog nthuav.
Neeg tuag lub cev los yog pov tseg, decompose pab decomposer, hu ua detritus. Vim hais tias cov zaub mov saw, uas pib li txawv txawv yog detrital.
Muaj ntau ntau txawv decomposers. Ntawm lawv yog cov fungi, cov kab mob, saprophagous, necrophages thiab coprophagous.
Saprophagous - cov no yog cov decomposers uas pub rau lub cev ntawm lwm yam nyob beings. Necrophages tseem pub rau cov cev thiab carrion. Coprophagous pub rau organic pov tseg beings. Tag nrho cov muaj tus kab mob yuav pab tau khaws cia rau hauv lub purity ntawm qhov, ua rau ib tug lub neej tshiab thiab txoj kev loj hlob uas muaj sia nyob. Txawm tias muaj tseeb tias ib txhia neeg xav txog cov qias beings, yog tsis muaj lawv nws yog tsis yooj yim sua xav txog tej yam ib tug noj qab nyob zoo biosphere.
Piv txwv ntawm trophic chains
Nws yog tsis yooj yim kawm trophic saw. Qauv no yuav pab kom to taub leej twg thiab leej twg noj. Qhov tseem ib txwm yog grazing trophic saw. Nws pib nrog nroj tsuag. Yog li ntawd, koj yuav pib nrog lub cereal. Lawv muaj nyob rau hauv daim ntawv teev cov nyiam hares. Luav - yog consuments thawj kev txiav txim. Luav noj hma. Hma - nws consuments thib ob kev txiav txim.
Trophic chains yuav muaj nyob rau hauv cov dej. Koj yuav tau pib nrog lub phytoplankton, uas yog tau los pab txhawb lawv tus kheej ntawm nws tus kheej. Tab sis lawv pub rau zooplankton. Zooplankton - me me khoom noj khoom haus fishes. Thiab lawv, nyob rau hauv lem, ua tus nyiam kho pike. Tab sis nws, dhau lawm, muaj peev xwm ua ib tug neeg lub noj mov.
Detrital zaub mov saw tsis muaj xws li ntau yam thiaj li koom. Feem ntau nyob rau hauv lawv cov muaj pes tsawg leeg - cia li pov tseg los yog neeg tuag thiab ib tug tsiaj uas pub tau mov rau lawv. Lub nto moo tshaj plaws decomposers yog cov kab mob thiab fungi.
khoom noj khoom haus webs
Khoom noj khoom haus chains tsis tau siab muaj kev cuam tshuam rau tag nrho lub neej ntawm cov biosphere. Tom qab tag nrho, yog hais tias peb xav hais tias tag nrho cov tu noob hares, hma thiab hma tsis tuag. Lawv yuav cia li noj lwm yam tsiaj, txawm hais tias tus xov tooj ntawm no txhom yuav raug muab txo. Qhov no ntuj tshuav nyiaj li cas yog tswj los ntawm lub trophic tes hauj lwm.
Khoom noj khoom haus webs tej zaum heev, heev tsis meej pem. Nws tsis yog ib qho yooj yim to taub yuav ua li cas ib tug ntau ntawm cov tsiaj xav noj ib co nroj tsuag thiab cov tsiaj uas hides tej me me tsiaj. Koj muaj peev xwm mus txog ib tug loj tus naj npawb ntawm ntau cov zaub mov chains. Lawv yog cov tshwj xeeb tshaj yog nplua nuj nyob qhov twg sab los ntawm sab uas nyob ib sab mus rau ib tug loj tus naj npawb ntawm nyob quavntsej.
Lub ntiaj teb no lwm tus txiv neej, yuav ib tug ntau ntawm cov neeg tsis paub thiab nthuav lub sij hawm. Ib tug ntawm lawv yog cov trophic saw thiab network. Lub elaborate xwm ntawm lub mov saw los pab ib tug ntau yam ntawm cov nroj tsuag thiab cov tsiaj nyob ua ke nyob rau hauv tus kwv tij thaj yeeb nyab xeeb nrog txhua lwm yam, mus nrhiav zaub mov rau lawv tus kheej thiab lawv cov hluas, thiab purify lawv tej vaj tse los ntawm dab tsi tau outlived nws lub sij hawm.
