Answer 2

4.

Step-by-step explanation:

4 per capita rate of increase occurs in the giraffe population in this year. The birth rate per year of giraffe is 14 whereas the death rate per year is 10 so only 4 giraffes are added to the population if the emigration rate is added without emigration rate, the answer is 2 giraffe per year. so we can conclude that there are 4 giraffes increase occur in the population. Per capita rate of increase is of population size over some period of time. It can be calculated by the number of births per parent that survive and reproduce.
