Bioaccumulation tshwm sim nyob rau hauv ib tug trophic theem, thiab yog nce nyob rau hauv concentration ntawm ib yam khoom nyob rau hauv tej ntaub so ntswg ntawm kab mob lub cev vim nqus los ntawm cov zaub mov thiab ib puag ncig. Yog li, bioconcentration thiab bioaccumulation tshwm sim nyob rau hauv lub cev, thiab biomagnification tshwm sim hla trophic (chaw noj mov) qib.
Yog li ntawd, bioaccumulation tshwm sim li cas?
Bioaccuulation yog qhov tsuj zuj zus ntawm cov tshuaj, xws li tshuaj tua kab lossis lwm yam tshuaj, hauv lub cev. Bioaccumulation tshwm sim Thaum lub cev absorbs ib yam khoom ntawm tus nqi sai dua qhov uas cov khoom poob los ntawm catabolism thiab excretion.
Ib yam li ntawd, thaum cov kab mob kis tau los ntawm ib lub cev mus rau lwm qhov thiab ua kom muaj zog ntau dua nrog txhua qhov kev hloov pauv nws hu ua dab tsi? Bioaccumulation yog txheej txheem los ntawm cov co toxins nkag mus rau hauv lub vev xaib khoom noj los ntawm kev tsim hauv tus kheej kab mob , thaum biomagnification yog cov txheej txheem uas co toxins yog dhau los ntawm ib trophic theem mus rau tom ntej no (thiab yog li nce hauv concentration ) nyob rau hauv a noj web.
Tsis tas li ntawd, qhov txawv ntawm bioaccumululation thiab biomagnification quizlet yog dab tsi?
Bioaccuulation hais txog kev sib sau ntawm cov tshuaj lom neeg hauv cov ntaub so ntswg ntawm ib lub cev. Biomagnification hais txog qhov nce ntxiv ntawm cov tshuaj lom neeg ntau dua tus tsiaj nyob rau ntawm cov khoom noj.
Dab tsi yog cov khoom uas feem ntau yuav dhau mus rau bioaccumulation los ntawm qib trophic?
Bioaccuulation thiab bioconcentration tshwm sim hauv txhim kho hauv cov ntaub so ntswg adipose ntawm successive qib trophic : zooplankton, me nekton, ntses loj, thiab lwm yam. Txhua yam uas noj cov ntses no kuj noj ntau dua. qib ntawm mercury cov ntses muaj sau tau.
