Essay

Refer to the figures.
Figure 1
Figure 3
You are studying two islands (Figure 3) that have recently experienced volcanic activity. Both were formerly forested with palm trees. On island 1, a heat wave resulting from the volcanic eruption leads to the destruction of all the above-ground vegetation (middle figure). On island 2, a lava flow resulting from the volcanic eruption (right figure) completely covers the island.Answer the following questions:
a) How have the resources, environmental conditions, and species communities likely changed on the two islands as a result of the volcanic eruption?
b) Assume that the frequency of eruptions on the islands follows the pattern shown in Figure 1. Using data from Figures 1 and 3, create a graph (this will be referred to as Figure 4) using the frequency of eruptions to show where island 1 and island 2 would be located on the spectrum of disturbance. The x-axis should be frequency and the y-axis should be intensity.
c) Based on the frequency and intensity of the eruptions you plotted in Figure 4, what type of successional response would you predict for each island?
