The go-to data point used to indicate whether an institution is helping students reach success has tended to be its graduation rate. Post-graduation employment is another indicator but the definition of student success has evolved to include many more areas.
However, many examples exist of non-linear and sometimes abrupt changes in ecosystems. A change may be gradual until a particular pressure on the ecosystem reaches a threshold, at which point rapid shifts to a new state occur. Some non-linear changes can be very large and have substantial impacts on human well-being.
Name __________________________________ Date ________ Period _______. Succession, a series of environmental changes, occurs in all ecosystems. The stages that any ecosystem passes through are predictable. In this activity, you will place the stages of succession of two ecosystems into sequence. You will also describe changes in an ecosystem and make predictions about changes that will take place from one stage of succession to another. The evolution of a body of water from a lake to a marsh can last for thousands of years.
