What would happen to the production of the high energy sugars if water or carbon dioxide were not available to plants?

There would be no production of high energy sugars in the plant.

Explanation:

Plants produce their food (autotrophism) in a process unique to them called PHOTOSYNTHESIS. Photosynthesis is the process whereby plants produce energy-storing sugars (glucose) in the presence of light from sun.

This photosynthetic process combines Carbon dioxide (CO2) and water (H2O) as reactants to form sugar (C6H12O6) and oxygen (O2) as products. The equation for photosynthesis is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

This means that water and carbon dioxide are strictly needed for the process of photosynthesis to occur in plants. Hence, if water or carbon dioxide were not available to plants, there would be no photosynthetic process and ultimately no production of high energy sugars.
