Question

A population of moose on avalon peninsula numbered 80 individuals in 2013. in the next year, 21 individuals were born, 12 died, 7 emigrated out of the peninsula and 6 immigrated in. the population thus grew by ____.

Answer 1

it would be 88 or increased

Explanation:

This is because, the equation for this is

(birth rate + Immigrated) - (death rate + emigrated)

21 + 6 - 12 + 7

27 - 19

you would then add the 8 to get 88 which mean the population would have overly increased

Answer 2

The population grew by 8, or 10%.

The gains from births and immigrating in were 21+6=27. The losses from deaths and emigrating out are 12+7=19. (Since it is a loss, it will be -19.)

27-19 = 8 total gained; 8/80 = 1/10 = 10%
