3. Warm up: • Succession Warm up; Brain Pop

4. Definition: • Natural, gradual changes in the types of species that live in an area; can be primary or secondary • The gradual replacement of one plant community by another through natural processes over time

5. Primary Succession • Begins in a place without any soil • Sides of volcanoes • Landslides • Flooding • Starts with the arrival of living things such as lichens that do not need soil to survive • Called PIONEER SPECIES

7. Primary Succession • Soil starts to form as lichens and the forces of weather and erosion help break down rocks into smaller pieces • When lichens die, they decompose, adding small amounts of organic matter to the rock to make soil

9. Primary Succession • Simple plants like mosses and ferns can grow in the new soil http://www.uncw.edu http://uisstc.georgetown.edu

10. Primary Succession • The simple plants die, adding more organic material • The soil layer thickens, and grasses, wildflowers, and other plants begin to take over http://www.cwrl.utexas.edu

11. Primary Succession • These plants die, and they add more nutrients to the soil • Shrubs and tress can survive now http://www.rowan.edu

12. Primary Succession • Insects, small birds, and mammals have begun to move in • What was once bare rock now supports a variety of life http://p2-raw.greenpeace.org

13. Secondary Succession • Begins in a place that already has soil and was once the home of living organisms • Occurs faster and has different pioneer species than primary succession • Example: after forest fires

17. Climax Community • A stable group of plants and animals that is the end result of the successionprocess • Does not always mean big trees • Grasses in prairies • Cacti in deserts

18. Succession Matching! • Work with table partners • Cut out the descriptions and pictures • Match the pictures to the descriptions and then glue together. (MAKE SURE IT HAS BEEN CHECKED FIRST! You will not get extra copies if you mess up.) • Glue into your lab journals. You will get a sticker when completed!
