Biomagnification , tseem hu ua bioamplification los yog lom magnification, yog ib qho concentration ntawm cov tshuaj lom, xws li tshuaj tua kab, nyob rau hauv cov ntaub so ntswg ntawm cov kab mob uas kam rau ua nyob rau hauv successively siab nyob rau hauv ib tug zaub mov saw.
Hais txog qhov no, piv txwv li biomagnification yog dab tsi?
Rau piv txwv , Txau ib lub pas dej los tswj yoov tshaj cum yuav ua rau cov kab ntawm DDT mus rau hauv cov hlwb ntawm cov kab mob hauv cov dej hauv microscopic, cov plankton, hauv marsh. Hauv kev pub mis rau plankton, lim-feeders, zoo li clams thiab qee cov ntses, sau DDT thiab zaub mov.
Ib yam li ntawd, biological magnification Class 10 yog dab tsi? Biological Magnification ➫ Cov txheej txheem uas muaj teeb meem & tshuaj lom cov ntaub so ntswg ntawm cov kab mob nyob rau theem siab dua hauv cov khoom noj. Nws tshwm sim thaum cov pa phem coj los ntawm cov kab mob nyob rau hauv lub hauv paus ntawm cov khoom noj khoom haus mus txog siab concentrations nyob rau hauv lub cev ntawm cov tsiaj nyob rau sab saum toj ntawm cov zaub mov.
Hais txog qhov no, biomagnification yog dab tsi thiab nws tshwm sim li cas?
Biomagnification txheej txheem tshwm sim Thaum qee cov tshuaj lom thiab cov kuab paug xws li cov hlau hnyav, tshuaj tua kab lossis polychlorinated biphenyls (PCBs) cov khoom sib txuas nce mus rau cov khoom noj khoom haus los ntawm kev ua haujlwm ntawm ib puag ncig thiab mus rau hauv av lossis hauv dej tom qab ntawd lawv noj los ntawm cov tsiaj hauv dej los yog cov nroj tsuag, Dab tsi yog biomagnification piav qhia?
Biomagnification , tseem hu ua bioamplification lossis biological magnification, yog qhov nce ntxiv ntawm cov khoom, xws li cov tshuaj lom neeg, hauv cov ntaub so ntswg ntawm cov kab mob ntawm qib siab dua hauv cov khoom noj.
