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? the zebras have a higher population growth than the lions have. zebras and lions are both experiencing a positive population growth. zebras and lions are both experiencing a negative population growth. the zebras have a lower population growth than the lions have.

Explanation:

Step1: Calculate lion population change

Population change = Births - Deaths - Emigrations+Immigrations. For lions, births = 4, deaths = 2 + 1=3, emigrations = 5, immigrations = 5. So population change for lions = 4 - 3-5 + 5=1.

Step2: Calculate zebra population change

For zebras, births = 5, deaths = 3, emigrations = 4, immigrations = 1. So population change for zebras = 5 - 3-4 + 1=-1.

Step3: Compare population changes

Since 1 > - 1, lions have a higher population growth than zebras, which means zebras have a lower population growth than lions.

Answer:

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