I think u are talking about the concentration of oxygen. For oxygen, the solulability in water is not very high and so the air bubbles still contain lot of oxygen when it reaches the water surface. Also, the surface water is always in contact with the air and it won't be leaking of air.
u could simply look at the reaction of your fishes to see if oxygen is enough in the lower level of your tank.
If u enough plants and not too many fishes, u may not need an air pump.
