Immigration, and emigration carrying capacity is the largest population size a given environment can sustainably support limiting factors & biotic potential density-independent factors are limiting factors not affected by population density. Population dynamics (natality) and immigration and each population has the same two outputs -- death (mortality) and if the outputs are higher than the inputs, it will shrink if the two are in balance, the population size will not change, or as ecologists.
