Nope! it's just a commercial slogan.
This statement is false.
<u>Explanation:</u>
If the results are the same, a hypothesis turns into a theory first.
A hypothesis is an assumed statement which may or may not be correct. Special experiments are designed under controlled conditions to find out whether the hypothesis is correct or not. If the Hypothesis is correct, it becomes a theory. A theory is a sophisticated explanation of the results which is further refined to make a law.
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.
