__New terms:__
primary succession- the development of plant and animal life in an area without topsoil; the development of biotic communities in a previously uninhabited and barren habitat with little or no soil. secondary succession- the progressive replacement of one community by another until a climax community is established. pioneer community - the first community to colonize a new area climax community - a community that doesn't undergo further succession; one that has reached equilibrium

__Assignment__
Using a keynote, iMovie or podcast:

Compare and contrast primary and secondary succession. (include descriptions of k and r-selected organisms as part of this comparision)

Describe a sequence of ecological succession that begins with primary succession and ends with a climax community. (example: volcano to jungle)

Describe a sequence of ecological succession that begins with secondary succession and ends with a climax community. (example: lake to coniferous forest)

Provide examples of real locations where primary and secondary succession have occurred or are taking place.
