Front

Can Prokaryotes or single-celled organisms such as nitrogen-fixing bacteria called cyanobacteria in aquatic biomes; the Rhizobium bacteria living symbiotically in the root nodules of legume plants like peas, beans, and peanuts; and the free-living Azotobacter, transform nitrogen gas into biologically usable forms?

Back

Yes, through nitrogen fixation
