Prediction: I predict that the closer the light is to the pondweed the (or the higher the light intensity) the more oxygen will be produced until a certain point where the temperature or carbon dioxide levels will be the limiting factor. The further away the light, the slower the oxygen bubbles will be produced so the less light the less photosynthesis will occur which is needed for the plant to make food. The rate increases (A) but only to a certain extent. Then they don't increase any more because of the other limiting factors of the carbon dioxide levels and temperature.
