The four factors that produce changes in population size are the birth rate, death rate, immigration, and emigration. The birth rate is the rate that the organism reproduces with the ecosystem, whereas the death rate is the rate the organism dies. If either the birth rate or the death rate is significantly higher than the other it has the potential to cause problems. If the birth rate is too high the species will have over population, and if the death rate is high the species could potentially go extinct. Immigration is the rate that an organism moves to a different area, and emigration is the rate in which an organism leaves an area. The main factors that affect the

Unformatted text preview: nutria in the video are the high birth rate. The species is reproducing much faster than they perish, so they are experiencing over population. Also, the fact that they were brought to Louisiana shows that the forced immigration of the species has caused serious problems to the Louisiana wetlands. Once the land is depleted of all the nutria’s food resources, it is probable that the species will emigrate from the area in an attempt to find the resources need for their survival.
