No it isn't. You are just wrong. Plant matter consists almost entirely of water and cellulose. The proportions depend on how watery the plant is. Because the majority of the dry mass of a plant is CARBON, which is not obtained from water or soil nutrients, increasing the available CO2 will increase the plant's growth, especially because of the water-sparing effect on leaf pores. Higher atmospheric CO2 concentration means the plant will lose less water to transpiration per molecule of CO2 obtained from the air.
See my previous link about Liebig’s law.
It is irrelevant. See above. I'm objectively right, you're objectively wrong.
No, read @Julian658‘s link.
