All right, so here we have a question about nitrogen runoff being investigated, which is happening from these organically fertilized cornfields that is affecting local streams and lakes.
00:13
We want to determine from sort of the keyword nitrogen runoff as well as the sort of concept that this runoff from a fertilized cornfield is affecting sort of the local ecosystem.
00:26
And we want to determine whether this focus is energy cycling, population ecology, tropic levels, or nutrient cycling.
00:38
And so going through each of the options, energy cycling would be a little bit of a stretch as the movement of nitrogen.
00:47
Nitrogen in and of itself doesn't particularly contain energy that can be utilized readily.
00:53
And so the cycle, if there is a cycle, wouldn't necessarily be about that.
00:56
And so we can roll that out.
00:58
As for population, ecology, while, you know, it's implied that we would be looking at populations of these local streams and lakes, it's quite likely that we would anyway.
01:10
It's not sort of explicitly stated here.
01:13
We could just be, you know, determining what the parts per million or parts per billion of a specific nitrogen molecule is in these streams and lakes, in which case it would have nothing to do with the sort of biotic or population...
