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.

Counter-clockwise rotation starting at 0º gives negative dihedral angles from -1º through

90º ending at -180º (the same dihedral angle  as +180º).

Grasslands   Grasslands are found on every continent except Antarctica, and cover about 16 per cent of the Earth’s surface.  They develop where there is not enough precipitation to support forests, but enough to prevent deserts forming.
