14.5 Ecological Succession
• Succession occurs following a disturbance in an ecosystem.
• Succession regenerates or creates a community after a disturbance.– a sequence of biotic changes– damaged communities are regenerated– new communities arise in previously uninhabited areas

14.5 Ecological Succession
• There are two types of succession.– primary succession — started by pioneer species like
lichens and some mosses

14.5 Ecological Succession
• There are two types of succession.– secondary succession — started by remaining species
left over. From for example a fire or hurricane.
