The sun is not a living thing. It is made up of gases, such as hydrogen and helium, rather than living cells, which are present in all forms of life
My best answer would be C I hoped I helped sry if you get it wrong
Polar because it always is below 32 degrees and has no rainfall
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.
