YCoral vs Reef
Coral thiab reef feem ntau tuaj ua ke hauv daim ntawv ntawm coral reef, tab sis ob qho tib si sib txawv uas ua haujlwm ua ib chav. Ob qho tib si corals thiab reefs coj ntau qhov kev txaus siab rau biology feem ntau thiab rau ecology thiab ib puag ncig kev tshawb fawb tshwj xeeb. Thaum ob qho tib si coral thiab reef tau kawm ntxiv, qhov sib txawv ntxiv ntawm lawv tuaj yeem nkag siab.
Coral yog cnidarian hauv chav kawm: Anthozoa nyob hauv ib puag ncig marine. Corals nyob hauv cov cheeb tsam uas muaj cov tib neeg zoo tib yam hauv daim ntawv polyp. Ua invertebrates, coral polyps tsis muaj lub cev pob txha, tab sis lawv tso cov calcium carbonate uas tsim cov pob txha tawv nyob ib ncig ntawm txhua coral polyp. Qhov exoskeleton no feem ntau yog tsim nyob ib ncig ntawm lub hauv paus ntawm polyp, thiab kev tso tawm tau txuas ntxiv mus rau ntau tiam neeg, uas tsim kom muaj lub pob zeb loj loj thaum kawg. Cov duab ntawm exoskeleton yog yam ntxwv rau txhua hom.
Muaj ntau dua 70,000 hom kab mob sib txawv hauv ntiaj teb, thiab feem ntau ntawm lawv nyob hauv cov dej sov sov marine. Lub npe hu rau txhua hom coral feem ntau yog ua raws li cov tsos mob sab nraud ntawm exoskeleton, uas yog tshwm sim los ntawm kev zais ntawm cov kab mob polyp. Nws yuav yog ib qho tseem ceeb uas yuav tau hais tias muaj ob lub ntsiab ntawm corals hu ua Hermatypic (reef-builders) thiab Ahermatypic. Nrog rau muaj ntau yam xim nyob rau hauv lub polyps nyob, coral colonies nthuav tawm ib qho kev ntxim nyiam thiab muaj yeeb yuj tsos rau lawv ib puag ncig. Ib qho ntawm cov yam ntxwv uas nyiam cov neeg saib coral yog qhov kev zoo nkauj ntawm corals.
Corals pub rau lwm yam kab mob xws li plankton thiab ntses me, los ntawm immobilizing tus tsiaj ntawm nematocysts. Kev loj hlob ntawm kev sib deev yog feem ntau nyob rau hauv corals, tab sis kev sib deev kev sib deev ntawm spawning kuj muaj nyob rau hauv lawv. Spawning yog qhov nthuav heev vim nws tshwm sim synchronously nrog rau lwm hom thaum tib hmo ntuj. Txawm hais tias lawv tau ua los ntawm cov tsiaj txhu, raws li lawv tau muab cais tawm, corals tshwm li puas tau tawg paj hauv qab dej.
Reef
Reef yog lub cev qauv uas tau tsim hauv qab dej los ntawm cov txheej txheem biotic lossis abiotic. Qhov zoo tshaj plaws-paub reefs yog cov coral reefs, uas tau tshwm sim los ntawm cov txheej txheem biotic hu ua reef tsim los ntawm cov nyob reef-building corals nyob rau hauv cov dej sov marine. Ntxiv nrog rau cov pob zeb ntuj no, tej zaum yuav muaj cov khoom siv dag zog xws li cov nkoj tawg ntawm ntug hiav txwv. Nws yog qhov nthuav heev uas cov pob zeb zoo li no muab cov chaw nyob zoo heev rau cov ntses thiab lwm yam kab mob hauv hiav txwv kom lawv tuaj yeem nkaum ntawm cov tsiaj nyeg yooj yim.
Biotic reefs xws li coral reefs thiab oyster txaj yog qhov tseem ceeb ntawm ecological tseem ceeb, muab chaw nyob rau ntau yam kab mob los ntawm microscopic algae mus txog rau cov vertebrates loj. Nyob ntawm qhov chaw thiab cov duab ntawm biotic reef, muaj peb hom tseem ceeb hu ua Fringing reef, Barrier reef, thiab Atoll reef. Fringing reef yog txuas nrog rau thaj av, thaum barrier reef yog tsim me ntsis deb ntawm thaj av tsim ib lub pas dej uas muaj kev tiv thaiv los ntawm nthwv dej, whereas atolls tau tsim qhov twg tsis muaj av nyob ib puag ncig.
Nws yuav yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov coral reefs puas tau hlub los ntawm kev tso tawm ntawm calcareous exoskeleton los ntawm coral polyps. Reefs yog lub cev tseem ceeb heev uas muab chaw nyob rau ntau yam kab mob.
Qhov txawv ntawm Coral thiab Reef yog dab tsi?
• Coral yog tsiaj muaj sia thaum lub pob zeb yog lub cev qauv.
• Reef yog qhov chaw nyob ntawm corals, uas tau tsim los ntawm kev zais ntawm coral polyps ntau tiam neeg.
• Corals yeej ib txwm nyob thaum lub pob zeb tuaj yeem tshwm sim los ntawm cov txheej txheem biotic lossis abiotic.
