  1. They eat roots to make space
  2. They pack the soil down hard
  3. They dig tunnels and feed the soil ✔

Why: Worm tunnels help water move and give roots room to grow. Worms also pass soil through their bodies and leave it in better shape.

Huh, didn't know that: Where earthworms are busy, they can turn over the top 6 inches of soil in 10 to 20 years.

The dad joke
Why did the worm take a nap? Because it was tired from turning the spring soil.
