Essay

Refer to the figure.
Figure 1
You are studying succession in an area affected by a volcanic eruption. Figure 1 shows the amount of volcanic activity over time, from no activity to high activity. Time periods with no activity indicate that the volcano is inactive and no disturbance is occurring; time periods with high activity indicate that the volcano is active and there are high levels of disturbance.Answer the following questions:
a) How would you describe the frequency of eruptions in terms of ecological timescales? Are eruptions common or rare in this area compared to the lifespan of organisms?
b) Using the frequency of eruptions, create a graph (this will be referred to as Figure 2) that shows where this type of event would be located on the plot of the spectrum of disturbance. Make the x-axis frequency (from low to high), and the y-axis intensity (from low to high).
c) Based on the frequency and intensity of the eruptions, what type of successional response would you predict for this area?
