Question

24 multiple choice 2 points which situation best demonstrates population density? deer migrate seasonally to avoid cold weather a forest contains both deer and wolves interacting in a food web a forest has 250 deer distributed across 20 square kilometers a new predator enters the forest ecosystem

Explanation:

Population density is calculated as the number of individuals in a population divided by the area they occupy. The option "A forest has 250 deer distributed across 20 square kilometers" provides both the number of deer (population size) and the area (20 square kilometers), which is the key information needed to calculate population density. The other options do not involve the relationship between population size and area. For example, deer migrating seasonally is about migration behavior, a forest with deer and wolves interacting in a food web is about community interactions (not density), and a new predator entering the forest is about ecosystem change (not density).

Answer:

A forest has 250 deer distributed across 20 square kilometers.
