Mushroom noj dab tsi
Raws li hom khoom noj khoom haus, nceb tau muab faib ua symbionts thiab saprotrophs. Symbionts parasitize cov kab mob nyob. Thiab saprotrophs suav nrog feem ntau ntawm cov pwm thiab cov kaus mom, cov poov xab. Saprotrophic fungi tsim ib ntus elongating mycelium txhua hnub. Vim qhov kev loj hlob sai thiab cov yam ntxwv ntawm cov qauv, mycelium yog ze ze nrog lub substrate, uas yog ib feem zom los ntawm secreted enzymes sab nraum lub cev ntawm cov fungus, thiab ces absorbed rau hauv cov fungal hlwb ua zaub mov.
Raws li qhov tseeb tias cov nceb tsis muaj chlorophyll, lawv yog nyob ntawm qhov muaj cov khoom noj khoom haus organic, uas yog npaj txhij rau kev noj.
Feem ntau ntawm cov fungi siv cov organic teeb meem ntawm cov kab mob tuag rau lawv cov khoom noj khoom haus, nrog rau cov seem ntawm cov nroj tsuag, cov hauv paus hniav rotting, lwj hav zoov litter, thiab lwm yam. ntawm kev puas tsuaj ntawm nplooj qhuav, ceg thiab cov ntoo tuag uas yuav litter hauv hav zoov.
Cov fungi tsim txhua qhov chaw uas muaj cov nroj tsuag, piv txwv li, nplooj poob, ntoo qub, tsiaj seem, thiab ua rau lawv decomposition thiab mineralization, nrog rau kev tsim ntawm humus. Yog li, fungi yog decomposers (destroyers), zoo li cov kab mob thiab lwm yam kab mob.
Mushrooms txawv heev nyob rau hauv lawv muaj peev xwm nqus tau ntau yam organic tebchaw. Qee tus tuaj yeem haus cov carbohydrates yooj yim, cawv, organic acids (qab zib nceb), lwm tus tuaj yeem tso cov enzymes hydrolytic uas decompose starch, proteins, cellulose, chitin thiab loj hlob ntawm cov substrates uas muaj cov tshuaj no.
Parasitic fungi
Lub neej ntawm cov fungi no yog ua los ntawm kev siv nyiaj ntawm lwm yam kab mob, incl. ntoo hlob. Xws li cov kab mob tuaj yeem nkag mus rau hauv cov kab nrib pleb los yog nkag mus rau hauv cov ntoo hauv daim ntawv ntawm cov kab mob nqa los ntawm kab noj qhov hauv cov tawv ntoo. Sapwood beetles raug suav hais tias yog cov nqa khoom tseem ceeb ntawm cov spores. Yog tias koj kuaj xyuas lawv kom ntxaws hauv lub tshuab ntsuas, tom qab ntawd ntawm cov kab ke ntawm cov kab mob sab nraud ntawm cov kab no, nrog rau ntawm lub plhaub ntawm lawv cov noob qes, muaj hyphae. Raws li qhov tshwm sim ntawm kev nkag mus ntawm mycelium ntawm parasitic fungi mus rau hauv cov hlab ntsha ntawm cov nroj tsuag, fibrous seals ntawm ib tug dawb xim yog tsim nyob rau hauv cov ntaub so ntswg ntawm "tus tswv", vim hais tias nws sai sai withers thiab tuag.
Txawm li cas los xij, nws tsim nyog sau cia tias muaj cov kab mob fungi uas ua rau lwm cov fungi. Ib qho piv txwv zoo ntawm qhov no yog Boletus parasiticus, uas tuaj yeem tsim tshwj xeeb rau cov kab mob uas yog cov genus Scleroderma (puffballs cuav). Tib lub sijhawm, tsis muaj qhov sib txawv ntawm qhov kev txhim kho no. Piv txwv li, qee pawg ntawm cov kab mob parasitic fungi, raws li qhov tshwm sim ntawm qee qhov xwm txheej, tuaj yeem dhau los ua saprophytes kiag li. Piv txwv ntawm cov fungi no yog tinder fungi, nrog rau lub caij nplooj zeeg nceb, uas tuaj yeem siv cov peev txheej ntawm "tus tswv tsev" thiab tua nws hauv lub sijhawm luv luv, tom qab nws tuag, nws siv cov ntaub so ntswg tuag rau nws lub neej. kev ua si.
