Answer 1

The correct option is E All of these

Population Density can be defined as the number of individuals per unit space. Many factors such as birth rate, death rate and dispersion affect population density. Death and emigration i.e. individuals moving out of a population tend to decrease population density, while births and immigration i.e. when individuals move into a population tend to increase population density.
