Compensation point is defined as the intensity of light at which the rate of photosynthesis is equal to the rate of respiration in plants. So, the oxygen produced during photosynthesis is used up in respiration, there is no exchange of gas between the plant and the atmosphere.

The Compensation Point is the point at which Photosynthesis and Respiration are in balance, so (in a perfect world) the amount of oxygen being produced by photosynthesis will just balance the amount being used by respiration.
