Population Characteristics

K and R

K- carrying capacity R- exponential growth

Three Characteristics

-Geographic Distribution -Density -Growth Rate

Growth Rate

Caused by Immigration and Emigration.

Density

Number of individuals per unit of area.

Logistic Growth

Occurs when a population's growth slows or stops following a period of exponential growth. ex. when people stop immigrating and start emigrating.

Exponential Growth

Occurs when individuals in a population reproduce at a constant rate.

Geographic Distribution

Range (the area inhabited by a population)

Carrying Capacity

The largest number of individuals that a given environment can support.

Immigration

The movement of individuals into an area.

Emigration

The movement of individuals out of an area.
