Qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom

Cov density dependent factor yog yam nws cov teebmeem ntawm qhov loj lossis kev loj hlob ntawm cov pejxeem txawv nrog cov pejxeem ceev . Nyob ntawd yog ntau hom density dependent limiting yam xws li; muaj zaub mov, predation, kab mob, thiab tsiv teb tsaws.

Yog li ntawd, dab tsi yog qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom?

Qhov ntom - raws li limiting yam ua rau cov pej xeem ntawm ib tus neeg loj hlob tus nqi hloov pauv-feem ntau, kom poob-nrog cov neeg coob zuj zus tuaj ceev . Ib qho piv txwv yog kev sib tw rau cov zaub mov tsawg ntawm cov tswv cuab ntawm cov pej xeem. Qhov ntom - kev ywj pheej yam cuam tshuam rau ib tus neeg loj hlob tus nqi ywj siab ntawm cov pejxeem ceev.

Yuav ua li cas cov kab mob ua haujlwm raws li qhov ntom ntom ntom ntom txwv? Parasitism yog suav tias yog ib qho ceev - nyob li limiting factor . Muab qhov no, parasites pab as a txwv yam kev loj hlob ntawm cov pejxeem vim lawv ua rau txo qis ntawm cov pejxeem ntawm cov hom hom.

Tom qab ntawd, ib tus tuaj yeem nug, dab tsi yog qee qhov piv txwv ntawm kev txwv tsis pub muaj kev txwv tsis pub muaj?

Cov pej xeem me me tshwj xeeb yog muaj kev pheej hmoo raug tshem tawm los ntawm density ywj siab limiting yam . Cov qeb ntawm density ywj siab limiting yam suav nrog hluav taws kub nyhiab, kev puas tsuaj ntuj tsim (xws li av qeeg, dej nyab, cua daj cua dub), thiab kev ua qias tuaj.

Dab tsi yog 4 qhov ntom ntom ntom ntom ntom ntom nti?

Cov density dependent yam yog yam nws cov teebmeem ntawm qhov loj lossis kev loj hlob ntawm cov pejxeem txawv nrog cov pejxeem ceev . Muaj ntau hom density dependent limiting yam xws li; muaj zaub mov, predation, kab mob, thiab tsiv teb tsaws. Txawm li cas los lub ntsiab yam yog qhov muaj khoom noj.
