Name: _________________________________ Succession – Option 1 Regular Worksheet 1. What does primary succession begin with? 2. In the Primary Succession timeline above what would be the pioneer species? 3. Primary succession is a very slow process. What must be created before the ecosystem can begin to evolve? 4. What is a climax community 5. What determines the climax community of each ecosystem? 6. Secondary Succession is a faster process than primary succession because there is already _________________ in the ecosystem. 7. In the Secondary Succession timeline above what would be the pioneer species? 8. How does the species diversity change in the succeeding ecosystems as the time passes? 9. Succession also takes place in aquatic systems. What is the first species to appear in this type of succession? 10. What determines the type of animals that appear during succession? (THINK: What animals would enter first and why?) Primary Succession Secondary Succession Write the following terms on the Venn diagram above where they belong: Forms on exposed rock No soil Can reach climax community Soil and microorganisms already there Pioneer species will emerge No previous living organisms there Most common type Occurs after volcanic eruptions Occurs after a hurricane Occurs after a wildfire Occurs after glaciers Number the following images #1 to #8 to show the correct order of Secondary Succession. #1 is done for you. _______ __#1__ _______ _______ _______ _______ _______ _______
