$\huge {\fbox{\pink{ANSWER:-}}}$

Cyanobacteria , also known as Cyanophyta, are a phylum of Gram-negative bacteria[4] that obtain energy via photosynthesis. The name cyanobacteria comes from their color (Greek: κυανός, romanized: kyanós, lit. 'blue'),[5][6] giving them their other name, "blue-green algae",[7][8] though modern botanists restrict the term algae to eukaryotes and do not apply it to cyanobacteria, which are prokaryotes.[9] They appear to have originated in freshwater or a terrestrial environment
