Why did the population of Jamestown decrease greatly between 1609-10?

The population of Jamestown decreased greatly between 1609-10 primarily due to a combination of severe food shortages, harsh winter conditions, and a lack of adequate supplies. The "Starving Time" during the winter of 1609-1610 saw settlers facing extreme hunger, leading to desperation and even instances of cannibalism. Additionally, conflicts with Indigenous tribes further strained resources and safety, contributing to the decline in the colony's population.
