Question

In a year, a population of lions had four births, two deaths from disease, one natural death, five emigrations, and five immigrations. In the same year, a population of zebras had five births, three deaths, four emigrations, and one immigration. Which best explains the data?
Zebras and lions are both experiencing a negative population growth.
Zebras and lions are both experiencing a positive population growth.
The zebras have a higher population growth than the lions have.
The zebras have a lower population growth than the lions have.

Answer 1

The zebras have a lower population growth than the lions have.

Lions: +4 births −3 deaths −5 emigrations +5 immigrations = +1 (net gain).
Zebras: +5 births −3 deaths −4 emigrations +1 immigration = −1 (net loss).
