Communities have a tendency to change from simple to complex in a process called succession. If a wooded area is cleared and left alone, plants will slowly reclaim the area. Eventually, the area will be transformed into woods again. This kind of succession, which occurs in areas where an existing community has been disturbed, but soil remains, is called
primary succession
secondary succesion
keystone species
prairie succession
