Detailed explanation1: The formula for calculating population density is Dp= N/A. In this equation, Dp is the density of population, N is the total population as a number of people, and A is the land area covered by that population.
Detailed explanation2: While atmospheric pressure may play a role in deciding factors for an organism to survive in a particular habitat, it does not affect population density.
Detailed explanation3: How to calculate populations density? Use the equation number of individuals/area (square units)=population density. Example 200 deer divided by 10 square kilometers equals 20 deer per square kilometer population density.
Detailed explanation4: What is the simplest method to measure population density in a given area? Count the number of organisms.
