Population growth, Biology

Increase in population size is known as population growth. It depends upon number of persons added to the population and number of persons lost from the population. Addition in population occurs by birth or immigration. Loss in population occurs by death or emigration. If more persons are added than lost, the population will show positive growth. If more persons are lost than added, the population will show negative growth. If addition and loss are balanced, the population will become stationary or show zero growth.
