The concentration of carbon dioxide in the atmosphere has been gradually increasing for many years. How might this increase affect photosynthesis? (please answer quickly)

It will increase the rate of photosynthesis as there will be more carbon dioxide ... however there may be a limiting factor which will limit the rate to keep it constant... Such as the opening if the stomata to receive more CO2 which in turn causes loss of water by transpiration.

cuz he's blad

explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
