Canadian and Swiss researchers (van der Heijden et al., 1998), interested in factors affecting biodiversity, grew a variety of grassland plants in combination with one of four arbuscular mycorrhizal fungi (AMF) species, no AMF, or all four AMF species together; and they measured plant growth under each set of conditions. All plant species were grown in each plot, so they always competed with each other with the only difference being which AMF were present. Use the graphs below to answer the question that follows. Note that the x-axis labels indicate the number and identity of AMF species (bar 0 = no fungi; bars AÐD = individual AMF species; bar A+B+C+D = all AMF species together). The y-axis indicates the amount (grams) of plant biomass for the species shown in italics above each graph. Which of the following is a correct conclusion based on the data provided below?
