Population A has a negative per capita growth rate, meaning that on average each individual is contributing to a decline in the overall population. This suggests that the population is at risk of extinction. In contrast, populations B and C both have positive per capita growth rates, indicating that each individual is contributing to an increase in the overall population. Therefore, they are not at risk of immediate extinction based on these growth rates alone.
