1: How is primary succession different from secondary succession?
Primary succession has soil and secondary succession already has soil.
2: What impact do humans have on succession?
Humans can impact succession in a number of ways by suspending succession or by restarting succession by using fire

3: What causes this primary succession? List at least two other examples of primary succession you can think of.
The cause of this succession is a glacier. Two other example of primary succession would be volcanoes and land slides
4: What are the 1st species to arrive after the succession event?
Lichens and mosses are the first to arrive
5: How does the rate of secondary succession compare to primary succession? Why do they differ? Explain.
Secondary succession is much faster because is already has soil, where primary succession does not and needs lichens and mosses to break down rocks so that they have soil.
Secondary Succession:
8: Fire is one cause of secondary succession. List at least 4 other examples of secondary succession.
Floods, harvesting, pest attack, and disease
9: Imagine a lawn on campus or in someone’s yard. Are there any examples of succession there now? If no one maintained it for five years, what might it look like? What would it look like after 10 years? 50? 100?
In ten years from now if we abandon our schools the lawns would definitely develop so that there would be small trees and a mini community for plants. In fifty years the trees would be huge and classrooms would be covered in plants. In hundred years the class room would most likely no longer be there and the lawn would have giant trees with a climax community.
