If the number of births in a population are greater than the number of deaths and theemigration rate is 2X the immigration rate what is likely to happen to the population sizeover time?it is likely to remain the sameit is likely to decreaseit would depend on the initial population sizeit is likely to increase

The population of a species is affected by various factors. The major contributors are birth rate, mortality rate, immigration and emigration. A high birth rate and immigration increase the population size in a given time slot. Mortality is decreasing due to better health care potentials. Emigration happens when individuals of the population select any other place to live depending on more space or refined opportunities.As we know that, (P1) Population size= Immigration + Natality - Mortality - Emigration If the emigration is doubled the numbers of immigration and birth rate is more than mortality rate then, P2 = I + (N + x) - M- 2I P2 = N + x - M- I The given data says that the birth rate is more than mortality but none of the specific figures is mentioned. That may be a few percentage of the mortality (N + x). According to the standard formula, emigration is the major factor that may bring a decrease in the population size. Thus, the population size decreases over a while because of the high emigration rate (2X of immigration). Therefore, the second option is correct.
