Solution
The correct option is B Positive
Population density (N) is the number of individuals present per unit area at a given time.
The population density is affected by four basic processes: natality, immigration, mortality and emigration.
Natality refers to the number of births, mortality refers to the number of deaths, emigration refers to the number of individuals who left the habitat and gone elsewhere during a given time period.
Immigration refers to the number of individuals of the same species that move into the population, from elsewhere, during a given time period.
As individuals are added to the population during immigration, it results in an increase in the population density. This shows that immigration has a positive effect on population density.
Natality (B) and immigration (I) contribute to an increase in the population density, whereas mortality (D) and emigration (E) contribute to a decrease in the population density.
