Can you explain how more life forms were able to be created because of cyanobacteria
patriot [66]

Cyanobacteria play an important role in the biosphere by converting atmospheric nitrogen into mineral nitrogen directly assimilated by other organisms. This capacity is of fundamental importance in coral reefs where nutrients are scarce.

Moreover, Cyanobacteria are the micro-organisms of choice for humans in various branches of biotechnology because of the many families of molecules that they produce and which have an interest in valorization.
