Hope it helps!

Answer 2

Answer:

The microorganisms that can fix atmospheric nitrogen in the soil are bacteria. There are many kinds of species of bacteria that have the ability to fix atmospheric nitrogen in the soil like Azotobacter and Rhizobium.

Explanation:

• Nitrogen fixation is the process of converting atmospheric nitrogen into nitrates so it can be used by plants.
• Nitrogen fixation is possible in some bacteria or prokaryotes. They contain a dinitrogenase enzyme complex, which catalyzes the conversion of dinitrogen to ammonia.
• Nitrogen-fixing bacteria can exist as free-living organisms or as symbiotic partners.
• Azotobacter, Beijernickia, Rhodospirillum, and cyanobacteria are examples of free-living nitrogen fixers.
• Rhizobium (found in the root nodules of legumes) and Frankia (found in the root nodules of non-leguminous plants) are examples of symbiotic nitrogen fixers.
