Qhov Tseem Ceeb Qhov txawv - Krill vs Plankton
Txawm hais tias Krill thiab plankton yog cov kab mob tseem ceeb heev uas tswj lub neej los ntawm kev ua thawj zaug kev sib txuas ntawm cov khoom noj hauv cov dej hauv dej xws li dej hiav txwv, hiav txwv, pas dej pas dej, thiab lwm yam, qee qhov sib txawv ntawm ob kab mob no. cov tsiaj no yuav nyob ntawm qhov zoo ntawm cov dej thiab qhov muaj teeb pom kev zoo. Tsis tas li ntawd, lwm qhov sib txawv uas txiav txim siab qhov kev faib tawm yog qhov muaj cov khoom noj uas suav nrog cov nyiaj nitrate, phosphate thiab silicates. Qhov sib txawv tseem ceeb ntawm ob kab mob no yog tias Krill yog ib qho me me crustacean pom nyob rau hauv ntau yam dej nyob hauv dej thiab pub rau phytoplankton thaum Plankton yog ib pawg ntawm cov kab mob me me uas ua rau cov kev sib txuas ntawm cov khoom noj feem ntau hauv cov dej hauv dej. Hauv kab lus no, qhov sib txawv ntawm krill thiab plankton tau tham ntxiv.
Krill yog dab tsi?
Krill yog ib qho me me crustacean uas vam meej hauv cov dej uas muaj zaub mov zoo thoob ntiaj teb. Nws yog ib hom zooplankton thiab pub tsuas yog ntawm phytoplankton ze ntawm dej. Tam sim no muaj ntau tshaj 80 hom krill pom. Krill raug txheeb xyuas los ntawm qhov pom tseeb gills pom hauv qab lub carapace ntawm thoracic ntu xya thiab yim. Muaj cov photophores, uas tsim lub teeb xiav thiab pom ntawm lub hauv paus ntawm lub plab pleopods, ze ntawm qhov ncauj qhov ncauj thiab ntawm qhov chaw mos.
Krill yog qhov khoom noj loj rau ntau cov tsiaj hauv hiav txwv xws li whales, cov ntsaws ruaj ruaj, squids, ntses, penguins, thiab lwm yam seabirds. Ntxiv mus, qee hom krill yog muag thiab siv rau tib neeg noj, aquacultures thiab thoob dej yug ntses, thiab hauv kev lag luam tshuaj.
Northern Krill
YPlankton yog dab tsi?
Planktons yog ib pawg kab mob sib txawv uas nyob hauv cov dej nplua nuj. Lawv ua qhov txuas tseem ceeb ntawm cov chaw nyob hauv dej thiab muab cov khoom noj tseem ceeb rau ntau cov tsiaj hauv dej. Feem ntau ntawm cov kab mob planktonic yog microscopic. Tab sis muaj ob peb hom uas tuaj yeem pom ntawm qhov muag liab qab (piv txwv li: jellyfish, krill, thiab lwm yam). Feem ntau cov plankton tsis tuaj yeem ua luam dej tawm tsam cov dej tam sim no. Muaj peb hom plankton; (a) phytoplankton, uas suav nrog diatoms, cyanobacteria, dinoflagellates thiab coccolithophores, (b) zooplanktons suav nrog krill, qe thiab larvae ntawm ntses thiab, (c) bacterioplankton suav nrog cov kab mob thiab archaea. Phytoplankton yog thawj cov neeg tsim khoom uas tsim lawv cov zaub mov los ntawm photosynthesis. Bacterioplankton ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv organic hauv cov dej hauv dej.
