How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? a.) Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? b.) What is carrying capacity? Do you think carrying capacity applies to people as well as to other organisms? Why or why not?
