Migration can increase population size by speading the animals (or people) over a wider area where there may be more resources. Migration (compression) into a single habitable area will increase the population density, but could cause either a numerical increase (more breeding) or a decrease (from limited resources).

What are four factors that affect the size of population?
1) Death 2) Birth 3) Emigration 4) Immigration
How is population size in an ecosystem determined by the relative rates of birth immigration emigration and death?
Birth and immigration both add individuals to a population, increasing the population size. Similarly, deaths and emigration remove individuals, reducing the population. So growth would be equal to the sum of immigration and births, minus the sum of emigration and deaths.
What does population influence?
Hey... Um-mm the answer is the two factor that affect population size is emigration and immigration. The diff of emigration and immigration is that emigration is when you leave some way for an ex Mexico, When Mexican leave there country they are emigrating. And when they come in to the US They are immigrate. :)
How are immigration and emigration rates related in a stable population?
In a stable population, immigration and emigration rates are closely related as they contribute to the overall population dynamics. For the population to remain stable, the number of people entering (immigrants) must balance with those leaving (emigrants), maintaining a consistent population size. If immigration exceeds emigration, the population will grow, while higher emigration than immigration will lead to a decline. Therefore, in a stable scenario, these rates are typically equal or closely aligned.
Identify the four processes that determine population growth: immigration, birth, emigration, and death, and explain the impact of each on population size. (14.3)?
Immigration and birth increase the population size as they are bringing more individuals into the population. While death and emigration decrease the population because death kills off individuals while emigration is a process in which individuals leave/exit the population.

The rate at which population size grows or declines depends on the rate of what?
births, death, immigration and emigration
What are two factors that increase population size and two factors that decrease population size?
Increase: Survival and Immigration Decrease: Death and Emigration
How can populations change in size?
Populations can change in size due to factors such as birth rates, death rates, immigration, and emigration. If the birth rate is higher than the death rate and there is more immigration than emigration, the population will increase. Conversely, if the death rate is higher than the birth rate and there is more emigration than immigration, the population will decrease.
How does Immigration and emigration and natality rate and mortality rate affect population?
Immigration increases the population, because new individuals are entering the area. Emigration decreases the population, because individuals are moving out of the area. Natality Rate increases the population, because new organisms are born. Mortality Rate decreases the population, because the organisms are dying.
What terms are used to describe the movement individuals into and out of a population?
The terms used to describe the movement of individuals into and out of a population are "immigration" and "emigration." Immigration refers to the arrival of individuals from outside the population, while emigration refers to the departure of individuals leaving the population. Together, these processes can significantly influence population dynamics and size.
How does emigration change into population size?
emigration
