What component, if any, is used to adjust the amount of water that is

It seems that the water level is not consistent; sometimes too little
to avoid skid marks.

The small black tube from the ballcock to the overflow tube
does the refilling of the bowl after the flush.
If the refill tube has fallen off or is not producing water,
the bowl level won't be correct.
