Lawv loj hlob nyob rau hauv txhua yam dej (tshiab, brackish, los yog marine) thiab yog photosynthetic: Lawv siv tshav ntuj los tsim zaub mov thiab ciaj sia. Feem ntau microscopic, cyanobacteria cov tuaj yeem ua kom pom tseeb hauv qhov chaw sov, muaj txiaj ntsig zoo, uas tso cai rau lawv loj hlob sai thiab "bloom" nyob rau hauv lub pas dej thiab lwm yam dej.

Ntawm no, vim li cas cyanobacteria tseem ceeb?

Tsis tsuas muaj cyanobacteria cov ua ib tseem ceeb lub hauv paus rau kev tsim lub ntiaj teb cov pa oxygen, tab sis nws kuj tau ua rau ntau lwm yam cwj pwm tseem ceeb rau tib neeg lub neej. Vim lawv yog photosynthetic thiab dej, cyanobacteria cov feem ntau hu ua "blue-green algae".

Tsis tas li ntawd, peb cov txiaj ntsig cyanobacteria muab rau ib puag ncig yog dab tsi? Daim ntawv thov ntawm cyanobacteria cov hauv kev tswj cov av thiab ib puag ncig suav nrog kev lag luam cov txiaj ntsig (txo cov nqi nkag), khoom noj khoom haus cycling, N₂- kho, bioavailability ntawm phosphorus, dej cia thiab txav mus los, ib puag ncig tiv thaiv thiab tiv thaiv kev ua qias tuaj thiab av degradation tshwj xeeb los ntawm kev txo cov

Kuj tseem paub yog, dab tsi ua rau cyanobacteria noj?

Feem ntau, photosynthesis nyob rau hauv cyanobacteria cov siv dej raws li tus neeg pub khoom siv hluav taws xob thiab tsim cov pa oxygen raws li cov khoom lag luam, tab sis qee tus kuj tseem siv hydrogen sulfide txheej txheem uas tshwm sim ntawm lwm cov kab mob photosynthetic xws li cov kab mob ntshav sulfur. Cov pa roj carbon dioxide raug txo kom tsim cov carbohydrates los ntawm Calvin voj voog.

Puas yog cyanobacteria xav tau oxygen?

Cov lus teb yog cov kab mob me me hu ua cyanobacteria cov , los yog xiav-ntsuab algae . Cov microbes ua cov photosynthesis: siv hnub ci, dej thiab carbon dioxide los tsim cov carbohydrates thiab, yog, cov pa.
