Yes. By burrowing, they turn soil over, help drainage, and let oxygen in to the ground. They also eat dead material, so speeding up the recycling of nutrients.

Depends on the plant; most plants enjoy the aeration and more readily available nutrients (by breaking up larger chunks into smaller). However, forests in the Midwest (indeed, many areas without "native" earthworms, where plants and worms co-evolved) suffer because of the increased nutrient cycling and alterations to the soil biota.

Yes worms help the plants in their growth.

By churning the soils ,, thereby breaking and aerating it. (Reducing its density and pack.)
In England the soil surface "sinks" 1 to 2 inches a year , by the effect of worm casts. Ironically , this is one of Darwin's historical works.

Obviously, yes. they dug soils and speed up breaking of soil nutrients
