ECOLOGICAL SUCCESSION INTERNET ACTIVITY

PART 1: Going to the Website 1. Open up the internet.

2. Go to this website:

PART 2: Defining Succession 1. Click on the first tab labeled "Succession". 2. What is a COMMUNITY?

3. It states in the description of a COMMUNITY, that a community is defined by its diversity of species living within it. What does DIVERSITY mean?

4. What do you think the word BIODIVERSITY means?

PART 3: Primary Succession

2015-2016

1. Now click on the tab labeled "Primary Succession".

2. Using the "Temperature and Rainfall" slider control, select "LOW" temperature and then watch the animation. *If you need to replay the animation, simply re-click on the Temperature/Rainfall control.

3. What creates the island at the very beginning?

4. What was the catalyst in this scenario? Why do you think this?

5. List out the order in which the different types of organisms invade and grow on the island:

1. 2. 3. 4. 5.

6. What happens with the TOP SOIL and NUTRIENTS as time passes?

7. How much TIME does this PRIMARY SUCCESSION take when temperature and

rainfall are LOW?

8. Now set the "Temperature and Rainfall" slider to MEDIUM and then watch the animation.

9. How much TIME does this PRIMARY SUCCESSION take when temperature and rainfall are MEDIUM?

10. Now set the "Temperature and Rainfall" slider to HIGH and then watch the animation.

11. How much TIME does this PRIMARY SUCCESSION take when temperature and rainfall are HIGH?

12. Does the change in temperature and rainfall change the types of organisms that invade the island, or in what order? Explain.
