See below.


Abiotically, population size can be regulated through natural disasters like floods, tornadoes, etc or things that affect climate like rain and temperature.

Biotically, population size can be regulated by food and/or natural predators. If a species doesn't have any natural predators it can be regulated by things like disease.
