carbon dioxide is removed from the solution.
the ph of the solution increases.
sugars are digested.
the solution becomes more acidic.
oxygen levels decrease in the solution.

Explanation:

Photosynthesis uses carbon dioxide (\(CO_2\)) as a reactant. When \(CO_2\) is removed from the solution (as it is used in photosynthesis), the pH of the solution increases. This is because \(CO_2\) can react with water (\(H_2O\)) to form carbonic acid (\(H_2CO_3\)) (\(CO_2 + H_2O
ightleftharpoons H_2CO_3\)), and a decrease in \(CO_2\) shifts the equilibrium to the left, reducing the concentration of hydrogen ions (\(H^+\)) which are responsible for acidity. Digestion of sugars is a part of cellular respiration, not photosynthesis. Photosynthesis produces oxygen, so oxygen levels would increase, not decrease. And since \(CO_2\) (which contributes to acidity when dissolved in water) is being removed, the solution becomes less acidic (pH increases), not more acidic.

Answer:

Carbon dioxide is removed from the solution.
The pH of the solution increases.
