Essay

Refer to the table and figure.
Table 2
Figure 4
You are studying the long-term effects of plate movement for two land masses, land mass A and land mass B. Your goal is to understand how land mass movement has affected the species found on each land mass. Land mass B joined with land mass A 30 million years ago. Table 2 shows the number of individuals of each species (species A-F) found living on land mass B over time. Figure 4 shows these data plotted.
-Use the data in Table 2 and Figure 4 to answer the following questions:
a) Sketch a vertical line on Figure 4 to indicate the time when land masses A and B joined (this will be referred to as Figure 5).
b) Which species on land mass B became extinct before land masses A and B joined?
c) Which species on land mass B became extinct after land masses A and B joined?
d) Which species was not originally found on land mass B but could have dispersed there from land mass A following the joining of the two land masses?
e) Which species showed no change in the number of individuals as a result of the joining of the two land masses?
