Refer to the figure.
Figure 4
You are studying how a contaminant moves through a food web and have collected the data shown in Figure 4. Suppose that for Figure 4B, you only sample individuals from a single trophic level. Based on this scenario, answer the following questions:
a) To which trophic level do individuals in Figure 4B belong? Explain your answer.
b) Based on both Figure 4A and 4B, do you see any evidence that your sampling of individuals graphed in 4B was biased? Why or why not?
c) If a species in this food web must consume a diet of 30% meat, which individuals would it need to hunt to have the lowest possible risk of exposure to the contaminants?
