• Carrying capacity
• logistis growth
• population density
• population growth rate

2. The movement of individuals into an area is called

• demography
• carrying capacity
• immigration
• emigration

3. The area inhabited by a population is known as its

• growth rate

6. What is the difference between immigration and emigration?

• immigration depends on the density of a population, while emigration does not
• emigration depends on the density of a population, while immigration does not
• immigration is the movement of individuals into a population, while emigration is movement of individuals out of a population
• emigration is the movement of individuals into a population, while immigration is movement of individuals out of a population
