Hi, in this video, we're going to talk about modeling ecosystem energy flows.
00:08
What we're trying to talk about is how scientists can model how energy flows through an ecosystem.
00:14
One of the ways that they do so on the topic of this video is through the use of an ecological pyramid, which shows the relative amounts of various parameters across traffic levels, meaning that it shows.
00:38
Shows how as you go up tropic levels, how these parameters change relative to each other.
00:47
Now, what kind of parameters are we talking about within the ecological pyramid? those can be number organisms, number of species, biomass, energy, and perhaps others.
01:14
Now let's talk about these ecological pyramids.
01:17
So there are two types of ecological pyramids.
01:21
There are those that are upright that look something like this, and they can be inverted like this.
01:30
If it's upright, it means that as you go up the traffic levels, whatever parameter you're studying decreases.
01:45
If it's inverted, that means that as you go up traffic levels, so the same direction where this is going to be the primary producer.
01:53
This is the primary consumer and so forth increases...
