A population of cheetahs has a birth rate of 5 and a death rate of 15. Immigration is 2, and emigration is 4. What is its population growth?

To calculate the population growth, we can use the formula:

Population Growth = (Birth Rate – Death Rate) + (Immigration – Emigration)

Plugging in the values from your question:

– Birth Rate = 5

– Death Rate = 15

– Immigration = 2

– Emigration = 4

Now we calculate:

Population Growth = (5 – 15) + (2 – 4)

Population Growth = (-10) + (-2)

Population Growth = -12

The correct answer is B. -12. This means the population is decreasing by 12.
