__ What is Emirgration? __ The size of a population can change when organisms come into or leave a population. Emigration is when orgaisms move out of a population. Emigration occurs when part of a population is seperated from the other part of that population. Organisms emigrate because their habitat doesn't meet their needs, so they leave and go somewhere else. If organisms are permanently seperated from their population, that organism will no longer be a part of that population.[1]

__ Are animals the only living things that can Emigrate? __ Alot people emigrate too, Most people emigrate for political or economic reasons. People who emigrate are called emigrants. [2] __Examples__ For example, if food is short, member of a deer population could wander off looking for better grassland. Animals need certain things to survive and sometimes their population doesn't have enough food for all the animals or there is none at all, That is why animals emigrate. Animals Emigrate alone or in a large group. [4]
