Nitrogen fixation on marine particles is important in the global ocean

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found in marine waters can convert nitrogen gas (N2) to ammonia (known as N2 fixation), and thereby supply the marine food web with nitrogen.
