Use the following information to answer the question.A group of Canadian and Swiss researchers wanted to know if the diversity of arbuscular mycorrhizal fungi (AMF) was important to the productivity of grasslands. Specifically, they wanted to know if it mattered which specific AMF species were present, or just that some type of AMF was present. They grew various plants in combination with one of four AMF species (A, B, C, and D), no AMF species (O), or all four AMF species together (A + B + C + D); 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 species were present. The results showing the biomass of five different grass species along with the total biomass of the combined grass species are shown in the graphs. (M.G.A. van der Heijden et al., Mycorrhizal fungal diversity determines plant biodiversity, ecosystem variability, and productivity, Nature 396:69-72 (1998)).What is the major difference between Bromus erectus (graph f) and the other plant species (graphs a-d) included in the study?
