-Migration - Individuals in a population may move from one place to another and these movements may change
the size of populations;
-Infant mortality - the higher the infant mortality the lower the population growthrate ;
-Natural enemies - Presence of natural enemies such as predators and pathogens reduced population growth rate
and vice versa ;
- Sex ratio ; This is the ratio of females to males in a population. The more the females the greater the
population growth rate ;
- Fertility - This is the number of offspring each organism give rise to during its life span. The higher the
