Q. Which of the following parameters are responsible for increasing the population?

NTA AbhyasNTA Abhyas 2020Organisms and Populations

Solution:

Population density will increase if the number of births plus the number of immigrants (B + I) is more than the number of deaths plus the number of emigrants (D + E). Under normal conditions, births and deaths are the most important factors influencing population density, the other two factors assuming importance only under special conditions. For instance, if a new habitat is just being colonised, immigration may contribute more significantly to population growth than birth rates.
