In 2001, a small population of mice in Colorado had 150 births, 110 deaths, 12 immigrants to the population, and 2 emigrants from the population. In 2002, Colorado experienced a severe drought. In this year, the birthrate for the population remained the same (150), but there
were 140 deaths, 2 immigrants to the population, and 12 emigrants from the population. Keeping in mind the equation for growth rate (r= [B
+ 1 - [D+]), explain what the population curve would look like for this population during the period from 2001 to 2002.

It would be a U-shaped curve because the population dropped and rebounded during these years.

It would be flat because the population experienced neither growth nor decline during these years.

It would show an increase in the population in 2001 and a flat line in 2002.

It would show an increase in the population in 2001 and a decrease in the population in 2002
