Looking at a partial energy web here, which does exactly what it sounds like, where we show where energy goes in an ecosystem or in a series of populations.
00:10
So in this particular example, we start with the autotrophs down at the bottom.
00:13
There's grain and grass.
00:15
The energy and the food that these plants make will go to the creatures that eat them.
00:27
And then when those things have energy because of what they ate, it will go to the creatures that eat them.
00:35
And so i say that this is a partial one because there's more to it.
00:40
It's a more complex ecosystem.
00:42
But we're going to look at this one little patch here.
00:45
Because we want to take the idea of what if we removed all of the grain from this little energy web from this ecosystem.
00:55
What would happen? well, you see that these individuals, the mice, the birds and the bugs, they would all have way less...
