Population Dynamics

All of the following are key features of populations EXCEPT

• size

• density

• dispersion

• disease

Population density is affect by the movement of people into a population. This is called

• Immigration

• emigration

• density-dependent

• density-independent

Population density is affect by the movement of people out of a population. This is called

• Immigration

• emigration

• density-dependent

• density-independent

What effect will an increase in natality have on a population?

• increase the population

• decreased population

• won't effect the population

• natality is a made up word

What effect will an increase in mortality have on a population?

• increase the population

• decreased population

• won't effect the population

• mortality is a made up word

All of the following are factors that are density-dependent EXCEPT

• competition for land

• outbreak of a disease

• about of available food

• the temperature in the area

The penguins are spread out evenly. This is an example of

• uniform dispersion

• random dispersion

• clumped dispersion

• unknown

These animals are scattered in this area in no particular order. This is an example of

• random dispersion

• uniform dispersion

• clumped dispersion

• unknown

Only the people that are circled will be counted. This is an example of

• sampling

• mark-recapture

• counting all the individuals in a population

• randomly guessing

This graph shows Human population growth. This growth is called

• exponential

• logistic

• random

• crazy
