Grass: Highly advanced
The relationships between predator and prey are very different on the open grassy plains. Grass may look to be a simple almost primitive plant, little more than leaves with roots. In fact, it is a highly advanced one, bearing tiny, unobtrusive flowers which rely not on insects to distribute their pollen but on wind. It produces horizontal stems running close to the surface or just below it. When fire sweeps across the plains, consuming the old dry leaves, the stems and the root stocks are unharmed and resprouts almost immediately. Grass leaves grow, not from the tip as do those of bushes and trees, but from the base. This is of benefit to the grazing animals for it means that even though the leaves have been cropped, they will continue to grow and new leaves will become available to be eaten.
