Population density is the number of individuals

• that are born each year.

• per unit area.

• that immigrate.

• that emigrate.

When the birthrate of a population exceeds its death rate, the population

• decreases

• increases.

• stays the same.

• increases then decreases

An S-shaped curve on a graph of population growth is characteristic of

• exponential growth

• logistic growth

• carrying capacity.

• delayed growth

Exponential growth in a population slows down or stops as

• resources become limited.

• rate of immigration increases. .

• rate of emigration decreases.

• birth rate increases.

Exponential growth rate means that each new generation of a population

• adds the same number of new individuals as the previous generation did.

• increases at the same rate as the previous generation.

• is the same size as the generation before.

• increases by a varying amount.
