The trophic chains yog soj ntsuam thiab kawm nyob rau hauv ib ceg ntawm biology, ecology. Qhov kev tshawb fawb no kawm txog kev sib raug zoo ntawm ib puag ncig thiab cov kab mob, nrog rau kev sib txuas uas yuav tshwm sim ntawm ntau hom.
Kev sib raug zoo tseem ceeb yog qhov uas tshwm sim dhau los ntawm khoom noj khoom haus Qee yam kab mob pub rau lwm tus, lossis ntawm lawv cov pov tseg, thiab yog li ntawd. teeb meem thiab lub zog tuaj yeem taug kev. Yog li ntawd, nyob rau hauv tsab xov xwm no nyob rau hauv peb lub site peb tham txog
Dab tsi yog cov khoom noj hauv av?
Food chains, in ecology, refer to the transfer of energy thiab teeb meem uas kis ntawm ib lub cev mus rau lwm tus. Tsis tas li ntawd, lawv coj mus rau hauv tus account lub zog uas ploj lawm, los ntawm kev ua pa, nyob rau hauv txhua pab pawg neeg ntawm cov kab mob. Cov khoom noj hauv av yog cov uas koom nrog cov kab mob hauv av, uas yog cov nroj tsuag thiab tsiaj txhu uas ua lawv txoj haujlwm tseem ceeb sab nraum dej ib puag ncig.
Nyob hauv ib thaj av uas peb nrhiav tau:
- Producing Organisms: Cov no yog cov tib neeg, feem ntau yog cov nroj tsuag, uas hloov inorganic teeb meem rau hauv cov organic teeb meem. Lawv yog cov tsiaj uas pib txoj saw.
- Primary consumer: yog cov tsiaj uas pub rau tag nrho cov neeg tsim khoom los yog ntawm qee qhov ntawm lawv qhov chaw, xws li nplooj, cag, noob los yog txiv hmab txiv ntoo. Lawv feem ntau yog cov tsiaj txhu, txawm tias cov tsiaj omnivorous kuj noj cov nroj tsuag.
- Yog li ntawd, lawv yog tsiaj txhu.
- :Lawv yog cov tseem ceeb nyob rau hauv ecosystems txij li thaum, nyob rau hauv ntau lub sij hawm, lawv ua raws li "umbrella" kab mob, tiv thaiv lub overpopulation ntawm tus cwj pwm predators thiab qhov tshwm sim ntawm ecosystem imbalance.
Nyob hauv ecosystems tsis muaj cov khoom noj yooj yim uas peb pom ib tus neeg ntawm txhua qhov txuas, tab sis yuav muaj ntau cov saw hlau sib txuas ntawm lawv tus kheej tsim yam uas hu ua "food web".
Difference of terrestrial and aquatic food chain
Txhua lub ecosystem muaj nws cov khoom noj, tsim los ntawm cov tsiaj thiab nroj tsuag uas nyob hauv biome. A cov khoom noj khoom haus ntawm lub ntiaj teb ecosystem sib txawv ntawm cov khoom noj hauv dej hauv qhov thib ob yog tsim los ntawm cov tsiaj uas nyob hauv dej ib puag ncig thiab thawj, cov tsiaj hauv av.
Qee zaus, ob txoj hlua tuaj yeem cuam tshuam hauv tib lub vev xaib, uas yog, cov tsiaj hauv dej tuaj yeem raug ntaus los ntawm cov tsiaj hauv av thiab rov qab. Piv txwv li, tus Common Kingfisher (Alcedo atthis), uas yog ib feem ntawm thaj av av, pub rau cov ntses me me uas nyob hauv dej. Lwm qhov piv txwv zoo yuav yog archerfish (Toxotes sp.), uas tua cov kab uas ya hla los yog perch ntawm cov nroj tsuag ze ntawm qhov dej.
Piv txwv ntawm cov khoom noj hauv av
Cov piv txwv ntawm cov khoom noj hauv av yog suav tsis txheeb. Tsis tas li ntawd, kev sib raug zoo tshiab raug tshawb pom txhua hnub raws li cov tsiaj sib txawv tau kawm ntxiv. Tom ntej no, peb qhia koj ob qho piv txwv ntawm cov khoom noj hauv av:
Paj 1
Marigold (Calendula officinalis) à European muv (Apis mellifera) à European muv-eater (Merops apiaster) à Red hma liab (Vulpes vulpes)
Hauv qhov piv txwv no ntawm cov khoom noj khoom haus hauv av, lub marigold yog cov khoom tsim tawm. Lub bee, tsuas yog pub rau paj paj thiab nectar xwb. Tus bee-eater yog ib tug noog uas tshwj xeeb hauv kev yos hav zoov, txawm tias nws tuaj yeem tua lwm yam kab. Thaum kawg, fox, txawm tias nws tsis tua cov neeg laus, nws tawm tsam cov zes uas cov noog tsim hauv av, preying ntawm hatchlings 'qe.
Paj 2
Sitka Spruce (Picea sitchensis) rau Alaskan Moose (Alces alces gigas) rau Snowy Fox (Vulpes lagopus) rau Grey Hma (Canis lupus)
The Sitka spruce is a conifer uas nws cones pub lub moose Qhov no tsis yog ncaj nraim mus yos hav zoov snowfox, tab sis nws tuaj yeem noj cov seem ntawm lub cev. Tus hma is an apex predator that common preys on the moose and hma.
