Answer the following questions on a separate piece of paper
1: How is primary succession different from secondary succession?
Primary succession is different from secondary succession because it begins with a with a place without soil and starts with the arrival of pioneer species unlike seconary succession, that begins with a place that already has soil and was once a livving place for organisms but it is just reestablishing the community because it has been disturbed.
2: What impact do humans have on succession?
Humans have a big impact on succesion because if they leave a farm abandoned everything will die or if humans set a fire it could spread into the forest, secondary succession will have to occurr.

3: What causes this primary succession? List at least two other examples of primary succession you can think of.
A glacier metls, leaving behind a field of rocks. Lichens and mosses begin to grow on the rocks and rocks begin to break apart. The lichens and mosses die and the combination of the dead lichens, mosses, and broken rocks form soil. Grasses and plants begin to grow in the soil. The grasses and plants being to die after a while and leave behind nutrients for the soil and that thickens the soil. The thick soil is now strong enough to have bigger things such as trees to grow. A forest has now been created by primary succession.
4: What are the 1st species to arrive after the succession event?
The 1st species to arrive are 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 much faster than primary succession. Secondary succesion is much faster because soil is there, it has just been disturbed. Primary succesion has been completly destroyed and has to start from scratch to get everything back.
Secondary Succesion:
8: Fire is one cause of secondary succession. List at least 4 other examples of secondary succession.
1) Volcanic eruption
2) Tree Harvesting
3) Hurricane
4) Flood
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?
Succession that is there now is the soil. If not maintained it for five years it would look terrible. Grass and long weeds would grow longer and longer. Soon enough everything would die.
