Quizplus · Accepted Answer

The first step in the nitrogen cycle is nitrogen fixation, in which gaseous nitrogen is converted into ammonia. This process is carried out by nitrogen-fixing bacteria such as Rhizobium and Azotobacter, as well as cyanobacteria and some archaea. Once ammonia is produced, it can undergo further transformations in the nitrogen cycle, such as nitrification and ammonification.
