Coccolithophores tuaj yeem photosynthesize ( autotrophic ) thiab tuaj yeem nqus cov organic ( heterotrophic ). Lub microscopic phytoplankton qhia ntawm no yog cov diatoms thiab dinoflagellates. Lwm cov phytoplankton hauv cov kab mob microscopic suav nrog coccolithophorids, silicoflagellates, kab mob, thiab kab mob.
Yog li ntawd, yog Coccolithophores diatoms?
Kev vam khom rau cov as-ham Ib qho tsawg silicate rau nitrogen thiab phosphorus piv tso cai coccolithophores kom ua tau zoo dua lwm hom phytoplankton; Txawm li cas los xij, thaum silicate rau phosphorus rau nitrogen ratio yog siab coccolithophores yog outcompeted los ntawm cov diatoms.

Coccolithophores puas muaj silica?
Ob lub ntsiab lus ntawm biomineralization pom nyob rau hauv marine plankton yog nag lossis daus silica (los ntawm diatoms, chrysophytes, synurophytes, dictyochophytes, choanoflagellates thiab radiolarians) thiab calcium carbonate (los ntawm coccolithophores , foraminifera, ciliates thiab dinoflagellates)3.
