You have set up a circuit that uses one battery to light two bulbs. One of the bulbs burns out, causing the other bulb to turn off. Why?
The electrical energy is stopped when the battery is disconnected, which causes the bulb to burn out.
The electrical energy cannot flow through the broken bulb, which causes the circuit to be broken.
The electrical energy is used up, which causes both bulbs to stop working.
