Question 2 • LPS Biology (CR) - MP1

Consider the following data. Rates for Cheetah Population from 2011 to 2012Cause of change20112012Deaths21Births54Immigration 61Emigration83Which would have to happen to keep the population growth of cheetahs in 2013 the same the previous years?

Answer
A
4 deaths, 7 births, 2 immigration, 6 emigration
B
3 deaths, 6 births, 5 immigration, 7 emigration
C
5 deaths, 2 births, 8 immigration, 3 emigration
D
1 deaths, 5 births, 3 immigration, 7 emigration

Explanation

Population growth equals births plus immigration minus deaths and emigration. In both 2011 and 2012, the net change was 1 cheetah: 5 + 6 − 2 − 8 = 1, and 4 + 1 − 1 − 3 = 1. Choice B also gives a net change of 1: 6 + 5 − 3 − 7 = 1, so it keeps growth the same.
