Answer 1

Answer:

Population density in a given habitat is influenced by four processes :

— Natality : It is the number of births in a population during a given period of time.

— Mortality : It is the number of deaths in a population during a given period of time

— Immigration : Number of individuals, coming from other habitats in a given period of time.

— Emigration : Number of individuals exiting from a given population in a given period of the time.

Mortality and emigration will, therefore decrease the population density while natality and immigration will increase it.
