Answer 1

• Microorganisms form a significant part of the ecosystem and participate in the production of minerals and gases like oxygen, carbon dioxide.
• They also feed on the dead and decaying matter by converting the complex compounds into the simpler ones.
• The bio-geochemical cycle, such as the nitrogen cycle is an important example of useful microorganisms.
• Azotobacter, Rhizobium, Clostridium are few examples of Nitrogen-fixing bacteria which play a primary role in transforming atmospheric nitrogen into inorganic compounds which are then used by the plants.
