Final answer:
Transitioning from hunter-gatherer societies to horticultural societies increases the food yield of a given land area, supporting higher population densities; hence, it's true that horticulture supports a denser population than foraging.
Step-by-step explanation:
The transition from foraging to horticulture indeed led to an increase in population density. When comparing horticultural societies to foraging, or hunter-gatherer societies, we can see that horticulture allows for a higher population density. The result of this change in subsistence behavior was that a given area of land yielded much more food for humans than had been the case in hunter-gatherer ecosystems. While population densities of hunter-gatherer communities ranged from around 0.02 to 0.2 persons per square kilometer, in early farming societies, they ranged from 25 to 1,000 persons per square kilometer. Therefore, the statement that there is a more dense population in horticulture than foraging is true.
