Explain the differences between a primary succession and a secondary succession. Give an example of each type of succession
What will be an ideal response?
In primary succession, there is little or no soil or life left, and whatever soil may be left is devoid of nutrients. It is succession from primary bedrock with extremely limited ability to support life. Examples include succession following glacial scouring, a landslide, or exposure of new rock by geologic or volcanic action. Typically, only pioneer species such as lichens can start succession in such areas. Secondary succession occurs after a severe disturbance, but significant soil, small organisms, and nutrients remain, making it far more hospitable to the reemergence of native life forms. Examples include old-field succession and succession after a fire or hurricane. Secondary succession will begin with higher soil fertility and may therefore begin succession at a point further along than the pioneer species that initiate primary succession.
