(2) The amount of glucose present would increase and ATP would no longer be available.

(3) The amount of carbon dioxide present would decrease and ATP would continue to be synthesized.

(4) The amount of oxygen present would increase and the amount of glucose available would decrease.

The answer is (1) The amount of oxygen present would decrease and the amount of carbon dioxide would increase, as the organisms in question are plants, and they take carbon dioxide from the air, photosynthesize, and release oxygen into the air. Without them, the amount of carbon dioxide would increase while the amount of oxygen decrease (since animals like us breath oxygen and release carbon dioxide).

 (1) The amount of oxygen present would decrease and the amount of carbon dioxide would increase.
