Students, today we're going to be answering this question in regards to the chapter on human interactions with the biosphere.
00:08
So the question here reads, what is equal to the growth rate of a population? is it the death rate plus fertility rate? is it biopotential? is it the carrying capacity minus the death rate? is it the birth rate minus the death rate? or none of these are correct? you can pause a video and pick which one you believe is the correct answer and we'll go over this shortly.

Okay, so reading this question, let's discuss about growth rate.
00:43
What is the growth rate? well, the growth rate of a population is determined by considering the difference between the number of the persons born per year.
00:54
So birth rate slash natality.
01:00
Okay, never heard that.
01:03
Never heard that.
01:04
Let me look at a natality.
01:07
Wow, that's something.
01:10
Natality.
01:11
Okay, the ratio of the number of births to the size of the population.
01:17
Oh, okay.
01:18
Sorry, that's interesting.
01:20
Sorry, i'm sorry, i went off track.
01:22
Okay, just never seen natality in my life.
01:25
Okay, anyhow.
01:26
Let me start all over.
01:27
The growth rate is basically a population that is determined by considering the difference between the number of persons being born per year or the birth rate and the number who die per year, which is your death rate or mortality...
