Dolphins need to breath air because they are mammals and all mammals breathe oxygen and give off carbon dioxide. This goes to the relation between plants and animals. Plants give us and other animals carbon dioxide, and we give them oxygen which they need to live.
In other, simpler words, animals and dolphins exchange different air molecules to keep each other alive and dolphins are part of this chain.
