Microscopic Sheep and Herders

[Don Schaeffer]

Well, that title pretty much covers the whole place, even where the citizens are just resting. These protists are grazers in a resource-rich region. They live in a resource-rich environment and feed on the product of protists who make the milk--i.e. predigested vegetation. They don't have to hunt. They just graze in the rich biome watery meadow. All seems pretty content. This area is populated by microscopic sheep.
