# CYANOBACTERIA Are you afraid of bacteria??? But do you know today we can live in earth only by the grace of this bacteria?😲😲 250 million years earlier, 1st oxygen was produced by this cyanobacteria or it is also called Blue-green algae.😯 These single-celled organisms live in fresh, brackish (combined salt and fresh water), and marine water. These organisms use sunlight to make their own food. A big different happened by a small creature that we can't see by our bare eyes. 😲😲. How beautiful the world is😍! I always encourage to do extra research before believing anything. ❤️ Happy reading💕
