Answer 1

$\huge \rm \red{answer}$

Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum of Gram-negative bacteria that obtain energy via photosynthesis. The name cyanobacteria comes from their color (Greek: κυανός, romanized: kyanós, lit. 'blue'),giving them their other name, "blue-green algae",though modern botanists restrict the term algae to eukaryotes and do not apply it to cyanobacteria, which are prokaryotes.They appear to have originated in freshwater or a terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria.
