To maintain the current population density, which of the following must occur? a. the death rate must be higher than the birth rate b. the birth rate must be higher than death rate c. the birth rate and death rate must stay the same with migration at 0 d. the birth rate and death rate must stay the same while migration can continue to rise

Hmm, well I think the answer is C.

I would say Answer A & B are incorrect because if the death rate was higher, soon there would be 0 people on earth. And B is incorrect because soon there would be overpopulation, the death rate would only slow this factor down.

So I believe C is the best answer out of C & D

Hope this helps you, Have a great day!
