Which organisms are capable of converting gaseous nitrogen in the air into a form that other living organisms can use?

Nitrogen Fixating bacteria ( such as cyanobacteria or clostridum) can convert gaseous nitrogen in the air into amonia, a compound that organism can use to make amino acid and other nitrogen-containing organic molecules
