Three examples of associations in nature include: 1) Sea anemones riding on the backs of hermit crabs where the two species protect each other from their different enemies; 2) Lactobacillus bacteria living inside the human gut, having a beneficial effect on human health; and 3) Leaf-cutting ants farming and feeding on specific fungi, which receive free food and protection. How can these three associations best be classified?

Nutrient Cycling  B.  Resource pulses are occasional events of ephemeral resource superabundance that occur in many ecosystems. Herbivores, like the 17-year periodical cicadas, can have enormous impacts on the growth and reproduction in forest plants. In their immature forms they feed primarily on roots belowground biomass. What types of statistical analysis would you use to the difference in % Leaf N (Figure 7)? (2pts)
