Population is the ratio of births to deaths.
THE PEOPLE IS NOT AWARE OF OUR POPULATION
Gene mutation causes the phenotype frequency in a population to change after each generation.
Reproduction

death of an animal could lead to reduction in population

A factor that causes a population to stop increasing is called a limiting factor, restricting growth through resources, predation, or environment.
