Question

the figures below refer to a herd of water buffalo. birth rate = 35 death rate = 7 immigration = 4 emigration = 17 what is this population growth? population increases by 41 population decreases by 15 population increases by 15 population decreases by 24

Explanation:

Step1: Calculate natural increase

Natural increase = Birth rate - Death rate = 35 - 7=28

Step2: Calculate net - migration

Net - migration = Immigration - Emigration = 4 - 17=- 13

Step3: Calculate population growth

Population growth = Natural increase+Net - migration = 28+( - 13)=15
