Moderate temperature, high light, nutrients availability, presence of water appears to be better conditions for Blue green algae growth in different habitat. Blue green algae are found, in all kinds of natural habitat that include marine, freshwater, soil, Biological soil crust, estuaries, surface of stone, paddy field, mangroves, roots etc. Numerous species characteristically inhabit and can occasionally dominate both near surface epilimnic and deep eutrophic hypolimnic waters of lakes. Many species are capable of growing on the soil and other terrestrial habitats where they take an important role in the ecosystem with regard to nutrient cycling. They flourish in the environment. The Successful growth of Blue green algae in different habitat includes extremes is due to the possession of certain properties related to this structure and metabolism. Blue green algae also protect themselves from growth inhibiting light intensities, with a variety of pigments that absorb harmful radiation (eg: Scytonemin in the sheath, Carotenoids and Xanthophylls) In this review study we Observe various habitat in which blue green algae grow and the various strategies they adopt to survive.
