Answer 1

The water in the bowl comes from the tank. So it can only have as much in the bowl as there is in the tank. The tank has a float in it. This float, depending on how high or low you set it, determines how much water fills the tank. When water fills the tank to a certain level determined by the float, it triggers a valve to close so no more water fills the tank. When you flush, the water from the tank is released to the bowl.
