I believe it has to do with the compensation point. That is, the light
level at which the amounts of CO2 consumed in photosynthesis and produced
by respiration balance out. Below that point the plant will produce more CO2
than consume, so there is no point in adding extra CO2. Of course, this
compensation would be extremely variable from species to species, and perhaps
would depend on other environmental conditions as well.
