Worms

There are 2,700 kinds of worms. They may be slimy, but they help the earth.

Worms have lived for 120 million years. They eat leaves, stems, and dead roots. Then, their bodies get rid of this matter. This makes rich soil.

One kind of worm from South America is eight feet long. Other worms are only a few inches long. They all dig tunnels and look for food.

If there were no worms, we would be in trouble. Dead animals and plants would pile up. Our dirt would not be good. So if you see a worm, tell it, “Thank you!”
