CONCLUSION
Micro algae play a vital role as biological indicators in determining quality of

waterbodies and pollution of the particular place. They are chemical modulators in the
aquatic ecosystem, they transform many inorganic chemicals to organic forms. Several such

algal species in spite of their characteristic adaptations to specific habitats have been found
