Under normal conditions, births and deaths are the most important factors influencing population density. However, if a new habitat is just being colonised, which of the following parameters contributes more significantly to population growth than birth rates?

Step-by-step solution

According to NCERT, under normal conditions, births and deaths are the most important factors influencing population density. However, if a new habitat is just being colonised, immigration may contribute more significantly to population growth than birth rates. This is a special ecological regime where the initial population build-up relies heavily on individuals arriving from other areas (immigration) before the established population can reproduce significantly (natality). Emigration and mortality would decrease
