Elizabeth Borer and colleagues argued that the ecosystem exploitation hypothesis makes specific predictions about plant and herbivore biomass under certain scenarios: In a community with only plants and herbivores, if nutrients increase, as with fertilization, herbivore biomass should increase, while plant productivity remains unchanged.  n a community with plants, herbivores, and predators, plant biomass should increase with added nutrients, while herbivore biomass should remain unchanged.
