Ecosystems like fields are naturally patchy with respect to nutrients, meaning within a single field there are high, medium, and low nutrient patches. Arbuscular mycorrhizal fungi (AMF) species can be helpful for plants to gain nutrients especially in low nutrient patches. The addition of nutrients to a field through fertilization reduces the natural nutrient heterogeneity and creates consistently high levels of nutrients throughout the field. Biologists conducted a 5-year experiment to determine how the addition of fertilizer to a field every year affects AMF diversity. Which set of rank abundance curves below best represents the change in AMF diversity over the 5 year experiment due to the addition of fertilizer
