They dig holes in the soil making it easier for the plant roots to grow. The "tunnels" created by the worm provide for faster growth, I think.

Worms eat the soil and leave their feces which are full of neutreants, which a plants root soak up.
Help plants grow,eat bacteria

Worms help enrich and aerate the soil, and therefore are very beneficial to plant root systems.
Most acers are sturdy enough to grow without the help of worms. Of course, earthworm activity helps all plants to grow but acers are no more (nor less) in need of such help.
yes, because worms help enrich soil and that would help the plant. plus it would airate the soil which gives oxygen the ability to go father down in the soil.
Worms crawl in your flowerbeds to help plants breath and they get muddy. They don't really care. They do not have eyes so they cannot see that they are dirty anyways.
they fertilize the plants. its kind of like giving your dog or cat special nutrients food... the worms poop out plant-enriching nutrients.
Well, you can have 2 transparent containers. The first one contains soil with recently dead plants, (not decayed) the container includes worms and you can show how worms help in decaying plants. The other one can have previously decayed plants so that the spectators can see the difference between them.
The plants in soil with worms will grow taller than those without worms. The worm play an integral role in which they allow plants to absorb more water and nutrients and thereby growing taller.
