Answer: Note in Figure 2 that as species richness increases, immigration rate decreases, and extinction
rate increases. At some value of species richness, the two lines cross, indicating that
immigration and extinction rates are equal. At that point, species richness is at equilibrium. In
this figure, equilibrium species richness is a little less than 400 species.
2. It is stable, as you can see from examination of Figure 2. When species richness is less than
the equilibrium value, the immigration rate is higher than the extinction rate, and so species
richness will increase. If species richness exceeds the equilibrium value, the extinction rate is
greater than the immigration rate, and species richness will decrease. Thus, even if species
richness deviates from the equilibrium value, it tends to return to it.
Explanation:It is a dynamic equilibrium. Figure 2 shows that when species richness is at equilibrium,
immigration and extinction are both still greater than zero: thus even though overall species
richness has reached equilibrium, individual species are still going extinct and new species are
still arriving. In this example, the rates of immigration and extinction are equal at about 20
(e.g., in units of species per year). This is the turnover rate.
4. Examine Figure 4, the graph of immigration rates for islands at three distances from the
mainland.
You should see that the immigration line for the near island is the steepest and the line for the
far island is the shallowest. Consequently, the immigration line for the near island crosses the
extinction line farthest to the right, and that for the far island, farthest to the left.
If you drop a vertical line from each of the three crossing points to the horizontal axis, you
will see that the near island has the highest equilibrium species richness (about 550), and the
far island has the lowest Hope this helps :(

ABOUT CAHOKIAThe Cahokia Mounds State Historic Site /kəˈhoʊkiə/ (11 MS 2)is the site of a pre-Columbian Native American city (which existed c. 1050–1350 CE[
) directly across the Mississippi River from modern St. Louis, Missouri. This historic park lies in south-western Illinois between East St. Louis and Collinsville. The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km2), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km2) and included about 120 earthworks in a wide range of sizes, shapes, and functions.
Cahokia was the largest and most influential urban settlement of the Mississippian culture, which developed advanced societies across much of what is now the Central and the Southeastern United States, beginning more than 1,000 years before European contact.

Which interval contains the greatest amount of data?
50-100
Correct. This interval stretches from Q1 to well above the median, so we can be sure that it contains more than 25% of the data. No other interval has more than 25% of the data, so this is the best answer.
ABOUT BOXPLOTThe numerical summary function aside from showing data characteristics, can also be used to create box and point charts or better known as boxplots. The numerical summary needed to construct a boxplot is the Median, 1st Quartile, 3rd Quartile, Lowest data value, and Highest data value. For large numbers of observations or data sizes, the Median can be replaced with Trirata. This is because to calculate the Trirata value using three quantities, namely the Median, Quartile 1, and Quartile 3, so it is considered to be more representative of the data when compared to the Median.
The center line inside the box on the boxplot represents the Median value. The sides of the box flanking the Median show the 1st and 3rd Quartile values respectively. Meanwhile, the two ends of the boxplot represent the lowest data values and the highest data values.
Boxplot is very good to use for data with a large number of observations because it only takes 5 numbers to construct it. It's easy and fast to construct a boxplot because you don't need to draw all the observation points in the boxplot. Because only five important observation points are visible, the data picture can be seen more clearly.
In explorative data analysis, boxplot has several important functions. Boxplot is often used in detecting whether there are extreme/outlier data in a data set. In many statistical analyzes it is assumed that the data follows a normal distribution. Boxplot can also be used in testing these assumptions. In addition, a boxplot can also be used in comparisons of several populations.
