Question

In a population of deer in one year, six deer were born, five deer emigrated, three deer were killed by predators, and one deer immigrated. What can be determined from this information?

Answer 1

I believe the answer is: we can determine that the population growth of the dear in that certain are is decreasing.

Let say that the initial population of the dear is x.

deers population after six deers born = x + 6

deers population after five deers emigrated = x + 6 - 5

deers population after three deers killed = x + 6 - 5 -3

deers population after one deer immigrated = x + 6 - 5 - 3 + 1

Final deer population = x - 1

Answer 2

So in your question, we can determined that the population growth of the dear in that certain are is decreasing. It because of the fact that the number of the deer that is killed, migrated and killed is greater than the deer that is born or added
