Question

What is survivorship? What does a survivorship curve show? Explain what the three survivorship curves tell us about humans, squirrels, and clams.

Accepted Answer

everyone. Let's take a look at this question together, in which of the survivorship curves. Does mortality increase later in life? Let's recall what we know about the different types of survivorship curves to figure out which type best represents that increase in mortality at a later point in life. So let's go ahead and start off by drawing what the survivorship curves look like. So we know that on the X axis we have time and on the Y axis we have percent of survival. And so the survivorship curves represent that change in the percent of survival as time increases. And so we have type one which looks just like this. This is type one, we have type two which looks something like this. So this is our type two. And lastly we have type three which looks just like that. And so we're trying to figure out which one of type 12 or three best represents that increase in mortality at that later point in life, which means that as time goes on, which one does mortality increase at that last point right here, which looks something like this or type one. Because that type one curve which you can see right here because Type one shows that as time goes on mortality increases at that later point in life right here because at the end of time that percent of survival is at its lowest, meaning that mortality is at its highest. The type one best represents the increase in mortality at a later point in life, which means that answer choice A is the answer we are looking for. And you can also see it in this chart here, where you see Type one, which is humans, so we have that steady flow of survival as time goes on until towards the end of time, our mortality increases, thus meaning that mortality increases at that later point in life. So Type one is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
