So we've got these two concepts that are community and an ecosystem, and they are differentiated by what they consist of, how broad they are.
00:09
A community is narrower than ecosystem because it only includes the biotic factors in an environment.
00:16
So biotic meaning living, it includes all of the organisms, plants and animals and all other groups of organisms.
00:24
While a community is broader and includes all the abiotic factors, that includes everything that's non -living.
00:31
So the environment itself, weather, salinity, different aspects about the environment that the organisms reside in, and then also includes the biotic factors.
00:41
So we're going to say an ecosystem is broader than a community.
00:45
So for a quick example, i'm going to draw some alligators over here, rough sketches of alligators, and then some fish around them.
00:55
So this is a community right now.
00:57
It includes the alligators and the fish...
