  1. KEY CONCEPT Ecological succession is a process of change in the species that make up a community.

  2. 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

  3. primary succession — started by pioneer species • There are two types of succession.

  4. secondary succession — started by remaining species • There are two types of succession.

  5. A system of biotic changes that regenerate or create an ecological community is known as • Migration • Factors • Succession • Erosion

  6. The development of an ecosystem in an area that has been covered by lava begins with the • Break down of rock by pioneer species • Migration of animals • Growth of trees and shrubs • Appearance of soil

  7. Lichens and mosses that first lived in uninhabited areas are examples of • Non-native species • Pioneer species • Primary species • Secondary species

  8. Secondary succession is most likely to occur • After a forest fire • With pioneer species • If a glacier shrinks • On a new volcanic island

  9. Which of the following statements about primary succession is true? • It begins with a climax community. • Small mammals are first to inhabit the area. • It only occurs after glaciers retreat. • It begins with bare rock.
