Chapter 27, Problem 2RQ
Summary Introduction
To describe:
The meaning of the equation for population growth using the variables
Introduction:
The changes in a population number could be due to birth rate, death rate, immigration, and emigration. Birth and immigration lead to adding individuals in a population and death and emigration leads to decrease individuals from a population. A wide gap between the birth and death rate could lead to faster growth in the rate of population.
