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.

Explanation:

Step1: Calculate population growth for lions

Population growth formula: \(Population\ growth=(Births - Deaths)+(Immigrations - Emigrations)\)
For lions: Births \(= 4\), Deaths \(=2 + 1=3\), Immigrations \(=5\), Emigrations \(=5\)
\((4 - 3)+(5 - 5)=1+0 = 1\)

Step2: Calculate population growth for zebras

For zebras: Births \(=5\), Deaths \(=3\), Immigrations \(=1\), Emigrations \(=4\)
\((5 - 3)+(1 - 4)=2+( - 3)=-1\)

Answer:

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