Population Ecology Review

Match the following

• immigration

• movement of individuals into an area

• carrying capacity

• largest number of individuals in a population that the environment can support

• emigration

• movement of individuals out of an area

The type of growth often seen with invasive species, when resources are unlimited and there are no native predators to control the population.

• Exponential

• Logistic

• Linear

• Cyclical

The area where a population lives.

• Geographic range

• Population density

• Population distribution

• Species evenness

The maximum number of individuals in a population that can be supported by a given ecosystem.

• Limiting factor

• Geographic range

• Population density

• Carrying capacity

Mark each limiting factor as density dependent (DD) or density independent (DI): Competition.

• DD

• DI

• Both

• Neither

The number of individuals per unit area.

• Geographic range

• Population density
