Why do toilets have a trap?

The main function of the P-trap in the toilet bowl, or any other p-trap, is to hold back the admittance of sewer gas into the room the fixture is placed in. It does this by being full of fluid. Under normal pressure sewer gas will not push the water out of its way and escape the drain.

Why does the water in the toilet bowl go up and down?

Toilet bowls are connected to sewer pipes, and there is air in the pipe between a toilet bowl and the air vent. Wind gusts cause the air pressure in the sewer pipes to fall, causing the bowls’ water to be drawn downward somewhat. When the air pressure goes back up as the wind slackens, the water goes back up a bit.
