Ya. Firstly, there is more water than the air and CO2 is only >1% of the air, so how can water be depleted before CO2.

Ya, i think you are right. I put water :(. At first, I thought that when plants photosynthesize, they can respire and produce more CO2, so I put water. However, I think CO2 is better... Oh no!!

You mean the cuddling one? I think it's because they lost heat to one another and not the surroundings so they would be warmer.
