Answer the following questions on a separate piece of
paper
1: How is primary succession different from secondary
succession?
Primary Involves the establishment of a community in a barren habitat, secondary involves the reestablishment of a community in an area that had been disturbed.
2: What impact do humans have on succession?
Humans can impace succession in different ways such as starting succession weather intentionaly or unintentionaly by different means

3: What causes this primary succession? List at least two other
examples of primary succession you can think of.
when a glacier melts, leaving behind a field of rocks and lichns and mosses begin to grow on rocks. Water break apart the rocks, which causes the lichens and mosses to die and form soil, which results tiny plants to grow and after the soil has enough nutrients for trees to grow, more plants will be able to grow
example: formation of new island
4: What are the 1st species to arrive after the succession event?
Lichens and Mosses
5: How does the rate of secondary succession compare to primary
succession? Why do they differ? Explain.
The rate of secondary succession is relatively faster than primary succession because in secondary succession the soil is already there
Secondary Succesion:
8: Fire is one cause of secondary succession. List at least 4
other examples of secondary succession.
Flooding of rivers, hurricanes, tornadoes and volcanoes.
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?
Yes, if it's abandoned the plants will die and secondary succession and it'll keep cycling nutrients and maintaining itself.
