We are being asked here for an explanation of productivity and why high productivity should lead to high species diversity in places like tropical forests and coral reefs.
00:20
So again, the idea here is that high productivity leads to high diversity of species in sites like tropical forests.
00:34
So one way to think about this is that all the productivity, which is all the growth of all the plants and all the animals over the course of, say, a year, that if you think of that like a pie, so i'm going to draw a circle here, and that circle represents all the productivity for a site.
01:01
All right.
01:03
And then i'm going to draw another pie.
01:05
And if i'm lucky, this pie will be bigger than the other one.
01:10
And this is a site with even greater productivity.
01:13
So i'll say this one has higher productivity.
01:18
And the idea here is that if you have a more productive site, you can cut this pie into more slices...
