One of the factor is the Sun's elevation where the UV reaches us at a much lower frequency when the sun is more distant. Next is our ozone, with our ozone depleting as time goes by, the amount of solar energy it can diffuse is much lesser thus the heat is much more than the previous decades.
Answer:
The Oxygen liberated in photosynthesis comes from photolysis of water.
The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.
Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.
However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)
