Which of the following tells you population density?
 A the number of births per year B the number of frogs in a pond. C the number of deaths per year D the number of bacteria per square millimeter
Explanation:

Detailed explanation-1: -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 explanation-2: -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 explanation-3: -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 explanation-4: -What is the simplest method to measure population density in a given area? Count the number of organisms.
