Which factors BEST help determine an increase in population size?

• birth rates and death rates

• emigration rates and death rates

• birth rates and immigration rates

• emigration and immigration rates

Which equation correctly represents a change in population density?

• Change in population density = (Births + Immigration) - (Deaths + Emigration)

• Change in population density = (Births + Emigration) - (Deaths + Immigration)

• Change in population density = (Births - Immigration) + (Deaths + Emigration)

• Change in population density = (Births + Immigration) + (Deaths - Emigration)

Which of the following is used to describe organisms leaving a population

• immigration

• population clumping

• allopatric speciation

• emigration

What happens to the size of a population if the birth rate decreases while the death rate remains the same?

• it stays the same

• it increases

• it decreases

• it increases, then decreases
