Question

To figure out the human population density of your community, you would need to know the number of people living there and
a. the land area in which they live.
b. the birth rate of the population.
c. the dispersion pattern of the population.
d. the carrying capacity.

Accepted Answer

Hi everyone. Here's our next problem. It says population density in a given area during a given time period is well, we need to think about what affects population density over time we have our population which is whatever size put in, and our answer choices give us factors of birth, immigration, death and emigration. So let's just go through each of these. Birth obviously is going to increase the population more individuals being born while death will decrease the population. And then we have immigration. Immigration. Immigration with an eye is the movement of individuals into a population, while immigration is the movement out of the population. So we've got birth and immigration increasing the population, death and emigration decreasing it. So we'd have to add birth and immigration. Birth plus immigration, Death and emigration. The two decreasing factors, and we're going to subtract death and immigration from birth and immigration. And we see that that is choice A. Here, birth plus immigration in parentheses minus death plus immigration and parentheses. So Choice A is our answer. The other answer. Choices all have the wrong order here. Um, Choice B has birth and death added together minus immigration. Immigration. Choice C. Um, has birth and immigration and switches, emigration and immigration. That's why that's incorrect. And Choice D adds birth. Immigration and immigration altogether and subtracts death. So that's why that's not correct. So, again, population density in a given area during a given time period is choice A birth plus immigration minus and parentheses. Death plus immigration. See you in the next video
