A community is a group of
species living in close proximity to one another, with the
opportunity for interaction. In this Lesson, we'll look at the
structure of communities, asking why particular combinations of
organisms form communities.
Well also examine the types
of interactions that exist among organisms in a community, from
competition between consumers for specific resources to the
relationship between predators and prey.
Finally, well study the
dynamics of communities over time, from the coevolution of species
to the succession of communities that take hold after an ecosystem
has been disturbed.
