Imagine a herd of wildabeast.
Now imagine the two species of grass on which it feeds. Now imagine the ten species of forbs and sedges it tramples in the processes. Now imagine the species of grasshopper that also eats the same grasses. Now imagine the soil microorganisms, the ticks that live on the wildabeast, and the birds that eat the ticks that live on the wildabeast, as well as the dung beetles that harvest wildabeast droppings. This is a simple list of species that may make up a grassland community.
