2012

2
1
Births
5
4
Immigration
6
1
Emigration
8
3

Which would have to happen to keep the population growth of cheetahs in 2013 the same the previous years?
4 deaths, 7 births, 2 immigration, 6 emigration
3 deaths, 6 births, 5 immigration, 7 emigration
5 deaths, 2 births, 8 immigration, 3 emigration
1 deaths, 5 births, 3 immigration, 7 emigration
Mark this and return

Answer 1

3 deaths, 6 births, 5 immigration, 7 emigration

(Reason: net change = births + immigration − deaths − emigration = 6+5−3−7 = +1, same as 2011 and 2012.)
