Vocabulary Chapter 1: Lesson 2 Birth rate Death rate Immigration Emigration Population density Limiting factor Carrying capacity

Birth rate The number of births per 1000 individuals A: Death rate

Death rate The number of deaths per 1000 individuals A: birth rate

immigration Moving into a population A: Emigration

Exiting a population: Moving out of a population Emigration Exiting a population: Moving out of a population A: immigration

Population Density The number of individuals in an area of a specific size. Examples: Population density= number of individuals/ unit area 20 butterflies/10 square meter

An environmental factor that causes a population to stop growing. Limiting Factor An environmental factor that causes a population to stop growing. Examples: weather, space, water, food

The largest population that an area can support Carrying Capacity The largest population that an area can support
