Which of these predictions follows from this hypothesis? If a certain “big-producer” is present, then biomass in a plot is high. If the big producer is absent, biomass is low. Productivity should be highest in the tropics, where species diversity is highest. There should be a strong positive relationship between the number of functional groups in an experimental plot and biomass. The more mutualists are present (e.g. beneficial fungi, nitrogen-fixing plants), the higher the biomass. • Show less
