Population Dynamics Review

Population density is...

• the number of individuals per unit area

• The number of males and females

• The number of cats your teacher has

• Individuals moving into a population from elsewhere

Growth rate is...

• whether the size of a population changes or stays the same

• whether the size of our classroom changes or stays the same

• the max number of species in an area

• the scientific study of human populations

A population that is stable...

• swings wildly between highs and lows.

• stays within a limited range.

• collapses and reaches a population size of 0.

• grows at a rapid rate and then crashes when it exceeds carrying capacity.

A population that is unstable...

• stays within a limited range.

• swings wildly between highs and lows.

• stays around carrying capacity.

• has about the number of organisms that the ecosystem can support.

What is exponential growth?

• A pattern where population growth increases rapidly.

• Population moving out of an environment.

• Population growth slows/stops after a period of great growth.

• A limiting factor.

What is it called when individuals move INTO its range from elsewhere?

• Growth rate

• Immigration

• Emigration

• Demographic Transition

Limiting factors are...

• the number of individuals per unit area.

• constant growth.

• things that control population growth.

• dramatic changes in death/birth rates.

What is logistic growth?

• Maximum number of individuals in an area.

• Competition between animals.

• Pattern where individuals reproduce at a constant rate.

• Growth that slows, stops, or reaches a plateau.
