Explanation:

A population bottleneck occurs when a population's size is sharply reduced. While this is most commonly caused by environmental disasters or human activities that kill a large portion of the population, it is not always caused by death. For example, a bottleneck effect can also occur through the founder effect, where a small group of individuals physically separates from the main population to colonize a new area, or through extreme habitat fragmentation that isolates a small subpopulation without direct mortality.
