Question

what are nitrogen fixing bacteria
and
what are nitrogen fixing algae​

Answer 1

★᭄ꦿ᭄ANSWER★᭄ꦿ᭄

1. Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.

2. Blue—green algae (Cyanobacteria) are a special group of prokaryotes. BGA are widely distributed all over the earth. While fixing carbon from CO2, certain BGA can fix dinitrogen from the atmosphere, and are called nitrogen-fixing BGA, including free living and symbiotic forms.

Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
