Earthworms: nature's little farmers.

An earthworm is built just right for squirming through the ground. It moves by stretching and shortening its body's ringlike sections. Eight tiny bristles covering each section dig into the soil and help pull the earthworm along.

As earthworms tunnel, they loosen and mix the soil just as farmers, plows do.

Worm-created tunnels bring needed air and water to growing plants. Plant roots push through the soil and follow the tunnel paths.

Besides tilling the soil, earthworms also enrich it. As earthworms wriggle, they leave behind their body wastes, or castings. These castings contain minerals that make the soil healthy.

Earthworms are busy little creatures!
