Qhov sib txawv tseem ceeb ntawm pyramid ntawm biomass thiab pyramid ntawm lub zog yog tias lub pyramid ntawm biomass qhia tias muaj pes tsawg biomass nyob hauv cov kab mob ntawm txhua qib trophic thaum lub pyramid ntawm lub zog qhia tias muaj zog npaum li cas yog khaws cia hauv daim ntawv ntawm tshiab biomass ntawm txhua qib trophic.
Ecological pyramids yog pyramid-zoo li daim duab ntawm lub zog ntws, biomass tsub zuj zuj, thiab tus naj npawb ntawm cov tib neeg ntawm ntau qib trophic hauv ib qho ecosystem. Muaj peb hom ecological pyramids li pyramid ntawm cov lej, pyramid ntawm biomass thiab pyramid ntawm lub zog. Pyramid ntawm cov lej sawv cev rau tus naj npawb ntawm cov kab mob ntawm txhua tus trophic. Pyramid ntawm biomass sawv cev rau biomass tam sim no ntawm txhua qib trophic thaum lub pyramid ntawm lub zog qhia lub zog muaj nyob ntawm txhua qib trophic. Tag nrho peb hom pyramids muaj txiaj ntsig zoo rau kev tsim cov qauv ecosystem.
Pyramid ntawm Biomass yog dab tsi?
Pyramid ntawm biomass yog ib qho ecological pyramid uas sawv cev rau biomass ntawm ntau qib trophic nyob rau hauv ib qho ecosystem. Biomass yog tag nrho cov huab hwm coj qhuav ntawm cov kab mob hauv ib cheeb tsam. Nws piv cov biomass ntawm txhua qib. Zoo ib yam li lub pyramid ntawm lub zog, thawj cov neeg tsim khoom nyob hauv lub siab tshaj plaws biomass. Feem ntau, tsuas yog 10 -20% biomass yog pauv los ntawm ib qib trophic mus rau qib trophic saum toj no.
Daim duab 01: Pyramid ntawm Biomass
Feem ntau, biomass pyramids yog upright txij li thaum muaj kev txo qis hauv biomass nrog nce qib trophic. Txawm li cas los xij, muaj inverted biomass pyramids thiab. Rov qab biomass pyramids tuaj yeem pom hauv marine ecosystems.
Pyramid ntawm Zog yog dab tsi?
Pyramid ntawm lub zog yog ib qho ntawm peb hom ecological pyramids. Lub zog pyramid qhia tias muaj zog npaum li cas ntawm txhua qib trophic ntawm cov khoom noj khoom haus. Yog li ntawd, lub zog pyramid sib piv cov zog hauv cov neeg tsim khoom, cov neeg siv khoom thawj, cov neeg siv khoom thib ob, cov neeg siv khoom qib siab hauv cov khoom noj khoom haus. Feem ntau, ib feem loj ntawm lub zog poob thaum mus los ntawm ib qib trophic mus rau tom ntej. Kwv yees li 90% ntawm lub zog poob raws li cov cua sov. Yog li ntawd, txhua qib saum toj no tau me dua. Lub zog siab tshaj plaws muaj nyob rau hauv thawj cov neeg tsim khoom, yog li lub zog pyramids muaj lub hauv paus loj lossis cov neeg tsim khoom.
Daim duab 02: Pyramid ntawm Zog
Cov neeg tsim khoom tseem ceeb nqus lub zog los ntawm lub hnub ci los tsim lawv cov zaub mov. Herbivores noj cov nroj tsuag thiab tau txais lub zog. Lawv tau txais tsuas yog 10%, thiab qhov seem ntawm 90% yog poob li cua sov. Carnivores noj herbivores thiab tau txais lub zog. Txawm li cas los xij, lawv kuj tau txais tsuas yog 10% ntawm lub zog ntawm herbivores. Qhov seem 90% yog poob raws li cua sov rau hauv ib puag ncig. Ib yam li ntawd, lub zog poob ntawm txhua qib. Yog li ntawd, lub zog hloov ntawm qib trophic feem ntau tsis txaus.
Dab tsi zoo sib xws ntawm Pyramid ntawm Biomass thiab Pyramid ntawm Zog?
- Pyramid ntawm biomass thiab pyramid ntawm lub zog yog ob ntawm peb hom ecological pyramids.
- Ob leeg sawv cev rau qib trophic hauv ib qho chaw nyob.
- Lawv tseem ceeb hauv kev nkag siab txog kev sib raug zoo ntawm cov kab mob thiab qib trophic hauv ib qho chaw nyob.
- Feem ntau cov pyramids pom tsuas yog plaub qib trophic vim tias feem ntau cov ecosystems tsuas muaj plaub qib trophic xwb.
- Feem ntau pyramids ntawm biomass thiab tag nrho cov pyramids ntawm lub zog yog upright.
Qhov txawv ntawm Pyramid ntawm Biomass thiab Pyramid ntawm Zog yog dab tsi?
Pyramid ntawm biomass sawv cev li cas mush biomass tam sim no nyob rau hauv txhua qib trophic thaum lub pyramid ntawm lub zog sawv cev rau lub zog ntws los ntawm qib trophic hauv ecosystem. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm pyramid ntawm biomass thiab pyramid ntawm lub zog. Lub pyramid ntawm biomass tuaj yeem yog upright lossis inverted, tab sis pyramid ntawm lub zog yog ib txwm upright. Ntxiv mus, biomass nyob rau hauv ib tug biomass pyramid yog ntsuas nyob rau hauv units ntawm kilograms ib square meter (kgm-2) thaum lub zog nyob rau hauv lub zog pyramid yog ntsuas nyob rau hauv units ntawm kilocalories (kcal).
Hauv qab infographic tabulates qhov sib txawv ntawm pyramid ntawm biomass thiab pyramid ntawm lub zog.
Summary – Pyramid of Biomass vs Pyramid of Energy
Pyramid ntawm biomass qhia txog tus nqi ntawm biomass ntawm txhua qib trophic hauv ib qho chaw ecosystem thaum lub pyramid ntawm lub zog qhia qhov ntws ntawm lub zog los ntawm ib qib trophic mus rau lwm qhov hauv ib qho ecosystem. Qhov no yog qhov sib txawv tseem ceeb ntawm pyramid ntawm biomass thiab pyramid ntawm lub zog. Feem ntau, tsuas yog 10 - 20% biomass raug pauv los ntawm ib qib mus rau qib tom ntej thaum tsuas yog 10% ntawm lub zog raug xa mus los ntawm ib qib mus rau qib tom ntej. Lub zog pyramids yeej ib txwm upright. Feem ntau, biomass pyramids yog upright. Tab sis muaj inverted biomass pyramids thiab. Yog li, qhov no qhia txog qhov sib txawv ntawm pyramid ntawm biomass thiab pyramid ntawm lub zog.
