Question

How do the blue green algae andsymbiotic bacteria convert atmospheric nitrogen into nitrogen compounds?

Answer 1

best known of these are the symbiotic Rhizobia (legume bacteria), nonsymbiotic free-living bacteria such as Azotobacter and Clostridium, and blue-green algae. Generally, in a symbiotic relationship, one organism contains chlorophyll and uses light energy to produce carbohydrates.

Answer 2

In BGA there is hetrocyst and bacterial cytoplasm there is found a enzyme ' Nitrogenase' which reduces atmospheric nitrogen to ammonia. This ammonia is converted to nitrite by nitrosomonas and nitrococcus. This nitrite is then further oxidised to nitrate ion by nitrobacter and nitrocystis.
