Answer:
nitrogen cycle
Explanation:
Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— N 2 \text N_2 N2start text, N, end text, start subscript, 2, end subscript—into biologically usable forms in a process called nitrogen fixation.
If the partial pressure increases, then the DO concentration in water will also increase. When the altitude is increasing, the total atmospheric pressure decreases, and then the partial pressure of oxygen is also decreasing
