Vocabulary Practice - Chapter 2: Populations

What is the movement of individuals out of an area called?

• Immigration

• Emigration

• Logistic growth

• Carrying capacity

Which term refers to the number of males and females of each age in a population?

• Age structure

• Population density

• Logistic growth

• Demographic transition

Which term best describes the pattern where a population grows rapidly and then levels off?

• Exponential growth

• Logistic growth

• Demographic transition

• Population distribution

What is the main difference between density-dependent and density-independent limiting factors?

• Only density-dependent factors affect population growth

• Density-dependent factors depend on population density; density-independent factors do not

• Density-independent factors depend on population density; density-dependent factors do not

• Both affect only small populations
