Grasshopper and ruminant grazing
- The annual nitrogen demand of an alpine grassland is largely derived from the nutrient cycle.
- Use of instantaneous N-input via N-deposition and biological N-fixation is small (not shown here).
- A cycle similar to the one shown here exists below the ground, although the "grazers" are different (soil animals).
- Note that grasshoppers recycle nearly as much N as ruminants.
