I need help explaining the four factors that produce changes in poplution and what could happen to the nutria population after all the land is depleted of the nutrias' food resources?
Answered by Ms. Sue
What are those four factors?
Answered by kia
I believe they are birth rates, death rates, immigration and emigration
Answered by Ms. Sue
Birth rates are the number of births born per x number of females. Death rates are the number of births per x number of the population. Immigration is the number of individuals per x number who come into the country. Emigration is the number of individuals who move out of the country.

What do you think would happen to the nutrias if they run out of food?
Answered by kia
They would all die
Answered by Ms. Sue
They'd either all die or possibly would move to a more life-sustaining environment.
