Answer:
Higher Photosynthesis, lower carbondioxide concentration in the atmosphere and vice versa.
Explanation:
Photosynthesis is greatly responsible for the fluctuation of carbondioxide concentration in the atmosphere because photosynthesis is the process where carbondioxide gas is used in large amount. If the vegetation occurs higher in the season, decrease will occur in the carbondioxide concentration of the atmosphere while on the other hand, if the less vegetation occur then there is higher amount of carbondioxide concentration in the atmosphere.
I believe it would be physics?
Water and Carbon dioxide combine during photosynthesis to make glucose and oxygen.
No the plants would keep growing and actually continue to grow until something changes it's life but the animal would die because cellular respiration is how the body or the cell in animals break down the glucose into atp witch is energy.
