Cov pyramid muaj zog ua tig upside down yog tias cov neeg siv khoom tsawg dua cov kab mob uas lawv noj. Piv txwv li, ntau txhiab kab tuaj yeem cog rau ntawm ib tsob ntoo. Tsob ntoo muaj ntau ntau biomass, tab sis itis tsuas yog ib tug kab mob. Yog li lub hauv paus ntawm lub pyramid yuav b me dua qib tom ntej.
Nyob rau hauv no hais txog, yog vim li cas ib tug pyramid ntawm cov zauv yuav inverted?
Ib inverted pyramid ntawm cov lej tuaj yeem pom nyob rau hauv ib qho ecosystem uas cov zej zog muaj ob peb cov neeg tsim khoom nrog cov biomass loj heev uas txhawb nqa qhov loj dua tus lej ntawm cov neeg siv khoom me me. Rau txhua cov khoom noj khoom haus, cov neeg tsim khoom khaws cia lub zog tshaj plaws thiab lub zog khaws cia txo qis ntawm txhua qib, muab qhov tsis tu ncua pyramid ntawm lub zog.
Ib yam li ntawd, lub pyramid twg ib txwm hloov pauv? Pyramid ntawm lub zog, qhia tus nqi ntawm lub zog ntws thiab / lossis kev tsim khoom ntawm qib trophic ua tiav. Cov pyramids ntawm cov lej thiab biomass yuav yog upright lossis inverted nyob ntawm seb qhov xwm txheej saw khoom noj nyob rau hauv tej ecosystem, whereas pyramids ntawm lub zog yog ib txwm upright.
Tsis tas li ntawd, puas yuav lub pyramid ntawm lub zog puas tau muaj qhov hloov pauv hloov pauv?
Ecological pyramids tau kuj hu ua trophic pyramids los yog lub zog pyramids . Pyramids ntawm tus lej ua tau yuav upright los yog rov qab , nyob ntawm qhov ecosystem. Ib qho nyom nyom thaum lub caij ntuj sov muaj qhov ncaj puab vim nws muaj lub hauv paus ntawm ntau cov nroj tsuag, nrog rau cov naj npawb ntawm cov kab mob txo qis ntawm txhua qib trophic.
Lub zog pyramid zoo li cas?
Ib lub zog pyramid (qee zaus hu ua trophic pyramid los yog ib ecological pyramid ) yog ib tug graphical sawv cev, uas qhia cov ndlwg ntawm zog ntawm txhua qib trophic hauv ib qho ecosystem. Lub hauv paus ntawm lub zog pyramid qhia qhov zog muaj nyob rau hauv thawj producers. Qhov thib ob theem trophic muaj cov neeg siv khoom thawj.

Vim li cas qee qhov kev hloov pauv tsis tuaj yeem thim rov qab?
Nws yuav ua tsis tau ntawv dua. Koj qhov siab yuav txo qis. Cov no yog cov kev hloov pauv tsis tau. Lawv tsis tuaj yeem thim rov qab txhua. Qhov sib txawv ntawm kev hloov pauv tsis tau thiab hloov tsis tau rov qab. Cov kev hloov pauv hloov tsis hloov Cov kev hloov pauv Feem ntau cov kev hloov ntawm lub cev yog hloov pauv tau. Tag nrho cov tshuaj hloov pauv yog hloov tsis tau
Cov lej ntawm cov lej lej puas tuaj yeem tsis zoo?
Tus cwj pwm ntawm cov lej lej nyob ntawm qhov sib txawv d. Yog tias qhov sib txawv sib txawv, d, yog: Qhov zoo, qhov sib lawv liag yuav nce mus rau qhov tsis zoo (+ ∞) Tsis zoo, qhov sib lawv liag yuav rov qab mus rau qhov tsis zoo infinity (− ∞)
Yuav ua li cas koj thiaj nrhiav tau cov lej ntawm cov lej lej lossis cov lej geometric?
Cov mis rau qhov suav ntawm n cov ntsiab lus ntawm geometric ib ntus yog muab los ntawm Sn = a[(r^n - 1)/(r - 1)], qhov twg a yog thawj lub sij hawm, n yog lub sij hawm tus lej thiab r yog tus qhov piv txwv
Cov enzymes puas tuaj yeem rov siv dua thiab vim li cas?
Enzymes yog reusable. Enzymes tsis yog reactants thiab tsis siv thaum lub sij hawm cov tshuaj tiv thaiv. Thaum ib qho enzyme khi rau lub substrate thiab catalyzes cov tshuaj tiv thaiv, cov enzyme raug tso tawm, tsis hloov pauv, thiab tuaj yeem siv rau lwm cov tshuaj tiv thaiv
Dab tsi yog cov lej suav tag nrho cov lej suav lej thiab lej lej?
Cov lej tiag yog feem ntau muab faib ua cov lej tsis sib haum xeeb thiab tsis sib haum xeeb. Cov zauv rational suav nrog tag nrho cov lej thiab feem. Txhua tus lej tsis zoo thiab tag nrho cov lej ua rau cov lej suav. Tag nrho cov lej suav nrog txhua tus lej ntuj thiab xoom
