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. :)
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 does Immigration and emigration and natality rate and mortality rate affect population?
Immigration and higher natality rates increase population, while emigration and higher mortality rates decrease it. Immigration brings in new individuals, boosting population, while emigration removes individuals, decreasing population. Higher natality rates lead to more births, contributing to population growth, whereas higher mortality rates result in more deaths, reducing the population size over time.
How does emigration change into population size?
emigration
What are the four processes that determine population growth?
The four processes that determine population growth are birth rate, death rate, immigration, and emigration. Birth rate and immigration increase population size, while death rate and emigration decrease population size. These processes collectively determine whether a population grows, shrinks, or remains stable over time.
What are the factors that affect a population's size size?
the factor are Death Rate Birth Rate Immigration
How do organisms join and leave a population?
By adapting themselves or being excepted into that specific population. Establishing a sense of belonging. Then, only leaving when the organisms adaptation is impossible or they have deceased from population.
What Factors affect population?
Factors that affect population size include birth rates, death rates, immigration, and emigration. Additionally, access to healthcare, socioeconomic factors, education, and environmental conditions can influence population growth or decline. Government policies and urbanization also play a role in shaping population changes.
