No, the oxygen levels in the air do not affect the rate of photosynthesis.
Explanation:
The rate of photosynthesis is affected by the following factors:-
- The external factor:- It includes the availabilty of sunlight, temperature, carbon dioxide concentration and water.
- The internal/plant factors:- It includes the number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal carbon dioxide concentration and amount of chlorophyll.
In the year 1905, Blackman gave the Law of limiting factors. This state that:- "If more than one factor affects a chemical process, then the rate is determined by the factor which is nearest to its minimal value."
