Hi there.
00:03
In this question, we have some of the levels of organization for biology.
00:10
We are missing the smaller levels, but we have several of the larger levels here.
00:18
And we are asked to put these in order from smallest of the ones available here to largest.
00:29
All right.
00:29
So let's go ahead and see what we can do here.
00:34
Looking at our choices here, the smallest of these options is going to be a single organism.
00:41
Because organism, the term organism, just means one individual.
00:49
And then if we have several organisms of the same species, what we have is a population.
01:19
Okay, and i'll back up to organism for a second here.
01:23
Again, that just means one individual.
01:31
Population is a group of these individuals from the same species.
01:36
The next one is going to be a biological community.
01:47
Biological community refers to all of the living species, or let's just say all of the living populations, in one location or one area, geographic area.
02:10
So a biological community refers to all of those different living organisms or living populations in one area.
02:21
Okay, let's go on then.
02:22
So far we have organism is the smallest, then population, then biological community.
02:29
Above that, then, is going to come ecosystem.
02:38
Whereas biological community was just all of the living things in an area, the ecosystem refers to all biotic and abiotic parts.
03:01
Sorry, trying to write in an area.
03:12
So now it's not just talking about the living things, the community, but we're also combining it with the non -living things.
03:21
The rocks, the weather, the sun, the clouds, all of those things are part of the ecosystem along with the living individuals.
03:33
All right...
