Primary succession is the colonizing of a new environment that lacks organisms and plant life. Primary succession is different from secondary succession; secondary succession is the colonizing of an environment that once supported life but was abandoned due to an ecological disturbance. An example of this is the colonizing of new land formed by lava flow.


Secondary succession can be described as the colonization of a habitat that once supported plant and animal life but was abandoned due to ecological disturbance. Types of ecological disturbances such as hurricanes and floods can empty a habitat.
