Populations

Which of the following is NOT an example of a Density Dependent Factor?

• Parasitism

• Natural Disasters

• Predation

• Competition

The movement of individuals into an area is known as:

• Supplementation

• Emigration

• Immigration

• Eradication

Typical population growth is described as:

• Logarithmic growth

• Logistic growth

• Linear growth

• Exponential growth

Emigration is:

• When a population continues to increase.

• When individuals move into an area.

• When individuals move out of an area.

• The study of human popuations.

Which of the following would cause a population to increase in size?

• Emigration

• Decreased Birthrate

• Immigration

• Increased Deathrate

In a given area, if the population of predators increases, the population of prey will _____________.

• increase

• decrease

• remain about the same

• go extinct

Which factor would contribute to an exponential growth rate in a given population?

• higher death rates

• less competition

• less resources

• lower birth rates

All of the following are density-independent factors except:

• seasonal changes

• hurricanes

• less space

• deforestation

Population density can be best described as:

• The amount of deaths that occur in a population

• The amount of births that occur in a population

• The amount of individuals in a given space.

• The amount of available nutrients in an ecosystem

If a population grows larger than the carrying capacity:

• birthrate may rise

• birthrate must fall

• birth and death rates remain the same

• death rate must fall
