Reza has a glass ball filled with water that contains tiny plants and shrimp that eat those plants. No material can get in or out, but light can get through the glass when it is placed in sunlight. The number of energy storage molecules in the plants and shrimp started out high, but then the glass ball was moved, and the number of energy storage molecules decreased. Was the glass ball moved into the light or into the dark? What happened to the amount of carbon in the air?
