For both the plots with the beetles added and the control plots, state the mean tree leaf area per plot that the scientists recorded after running the experiment for 18 months. The mean tree leaf area per plot that the Scientist recorded after running the experiment for 18 months wit the beetles added is 1.7m², S 2.2m² 13. Compare the trends in mean tree leaf area per plot for both the plots with the beetles added and the control plots over the 18 months of the experiment. The area of the control plat for thinoceros beetles has d has increased at a nearly constant rate, the other is a gradua decrease at first, then a sudden decrease, and finally a dradua 18 Figure 2. Mean leaf area per tree. Initial measurements were taken before (0 to 2 months) and after (7 to 18 months) beetles were added to 40 of 80 plants. The light gray round markers represent measurements taken of the control plots, to which beetles were not added. The black square markers represent measurements taken of the experimental plots, to which beetles were added. Measurements were made on all leaves to calculate the mean leaf area per plant. Error bars represent standard error of the mean. 14. Draw two diagrams that show the food chains for both the experimental and control plots. Include increase. interactions among predatory beetles (if present), ants, caterpillars, and piper plants. Revised January 2018 Page 4 of 5
