Cyanobacteria and it’s relation to the ecology system – Cyanobacteria are the photosynthetic and aquatic organism. They can synthesize their own food and live in the water. They were the algae. According to the evolution records, cyanobacteria were discovered 3.5 billion years back. They were called blue-green algae. They are prokaryotes. These bacteria are related to bacteria than algae. For several decades, after the invention of the electron microscope, although these bacteria were placed together with algae, they are substituted into the kingdom of Monera.

Cyanobacteria are by giving oxygen out phototropic bacteria, which uses water as an electron donor in photosynthesis. They are frequently found in nature-in soil, freshwater ponds, paddy fields, etc.. They play an essential role as they add organic matter to the soil and a number of them fix nitrogen and develop as mats on the surface of the soil, few live as symbionts with different organisms. Cyanobacteria get their title blue-green algae, which can be used for light for the photosynthesis. Some of the cyanobacteria are pink or red. These bacteria recover the saline of the soil by their ability to decrease soluble salts sodium ions and other chemicals that are toxic.

They have nitrogen fixation in addition to the ability of photosynthesis. Apart from nitrogen fixation, they excrete vitamin B12, ascorbic and auxin acid, which may lead to the growth of rice plants. The application of cyanobacteria with amounts of pesticides and fertilizers contributes to 10 percent gain in the crop yield.
