Post a 200- to 300-word response to the following: Explain the four factors that produce
changes in population size. Which factors are affecting the population size in the video?
What do you predict will happen to the nutria population after all the land is depleted of
the nutrias¿ food resource?
What video?
What population?
We haven't seen the video.
We'll be glad to critique your answer.
The four factors that produce changes in population size are birth rate, death rate, immigration, and emigration. Birth rate refers to the number of births occurring in a population over a certain period. Death rate, on the other hand, represents the number of deaths happening within a population during a specific time frame. Immigration refers to the movement of individuals into a population, and emigration represents the movement of individuals out of a population.
In the given video, the factors affecting the population size of nutrias might include birth rate, death rate, and possibly emigration. If the nutrias are breeding at a faster rate than they are dying, it could lead to an increase in population size. Conversely, if the death rate is higher than the birth rate, it could result in a decrease in population size. Additionally, if some nutrias are leaving the area due to environmental changes or lack of resources, it could contribute to a decline in population size.
After all the land is depleted of the nutria's food resource, it is likely that the nutria population will decline. Nutrias rely on their food resource to survive and reproduce, so the lack of food will lead to a decrease in birth rate and an increase in death rate. As their numbers decline, competition for the remaining food resources may become more intense, further reducing the population size. Eventually, if the decline continues, the nutria population may reach a point where it becomes unable to sustain itself, potentially leading to its local extinction.
