Question

Differentiate between natality and mortality.

Answer 1

Sr. No.	Natality	Mortality
1.	Natality is the inherent ability of a population to increase.	Mortality is the number of deaths of organisms in a population of a specific area over time.
2.	Natality is also called the birth rate.	Mortality is also called the death rate.
3.	It has an effect on populations by increasing their size.	It affects populations by reducing their size.
4.	Influencing factors include environmental conditions, potential natality (the maximum reproductive rate under optimal conditions), and realized natality (the actual birth rate).	Influencing factors are environmental conditions, potential mortality (the lowest death rate under best conditions), and realized mortality (the actual death rate).
5.	Natality is measured as the number of births per unit population per unit time.	Mortality is measured as the number of deaths per unit of population per unit of time.
