All right, so in this question, we're given this example where there's a butterfly species that is becoming endangered, in part because of the particular plant that it relies on, the lupine, is being forced out of its natural grassland areas due to construction.
00:23
But what this question is asking you in particular is to define the biotic factor.
00:30
In this community.
00:34
And so that leads us to think about what biotic means.
00:38
That is the question at hand here.
00:41
Now, when you break it apart, it has bio in it.
00:47
In bio, like biology, which is the study of life, is life.
00:56
So biotic factors are living factors in this community.
01:00
So let's go back and think about what things are alive here.
01:06
First we have the butterfly species and then the lupine plants.
01:11
The construction as a concept is not alive...
