APES- Succession Activity
1: How is primary succession different from secondary succession?
Primary succession occurs on ground which had no previous vegetation, including lava flows, bare rock and sand dunes. For example, newly created volcanic island. Secondary Succession follows the destruction or modification of existing vegetation, either naturally or by human activity. For example, section of a forest destroyed by fire.
2: What impact do humans have on succession?
Humans can impact succession in a number of ways by suspending succession in one phase or another or by causing an event that restarts the succession cycle (i.e. starting a forest fire).
3: What causes this primary succession? List at least two other examples of primary
succession you can think of.
It is when a species is introduced into a new area. It could be caused by humans moving species or migration.
4: What are the 1st species to arrive after the succession event?
The first species to arrive after the succession event is pioneer species.
5: How does the rate of secondary succession compare to primary succession? Why do
they differ? Explain.
The are of secondary succession compare to primary succession is 50 years.Primary succession begins in areas where no soil is present. Secondary succession occurs in areas where there is soil already present.
8: Fire is one cause of secondary succession. List at least 4 other examples of secondary succession.
A stable deciduous forest community. A disturbance, such as a wild fire, destroys the forest. The fire burns the forest to the ground. The fire leaves behind empty, but not destroyed, apples rot.
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?
