Which is likely to occur following the emigration and immigration of individuals into a population near an open body of water?

Immigration is the movement of individuals into a population, whereas emigration is the movement of individuals out of a population. Population numbers are determined by examining the rate of immigration, emigration, birth, and death rates. This question does not mention birth or death rates specifically, so it is assumed that these rates are equal to each other or held constant. If immigration is greater than emigration, then more individuals are entering the population than are leaving, leading to an increase in the population.
