"WebWhen the concentration of carbon dioxide in the air is high, plants are able to absorb more of this gas and use it to synthesize glucose at a faster rate. On the other hand, when the concentration of carbon dioxide is low, photosynthesis slows down because there is not enough of this gas available for the plants to use.
