Describe how the land and ocean nitrogen cycles are similar

Land and ocean nitrogen cycles follow the same cycle. From nitrogen fixation, Assimilation, Ammonification, Nitrification, and Denitrification. What differs are only the players processing in each cycle and the mode of transfer from one cycle to another. For example in nitrogen fixation, nitrogen on land came from the atmosphere while in the ocean it came dissolved nitrogen through precipitation or runoff. Players in fixation are bacteria such as rhizobium and its counterpart in the ocean are the cyanobacteria.
