Just wondering outloud having read a previous post on worms.
So, you have a patch of ground. It's barren, hardly a blad of grass,
nor weed in site and seemingly devoid of life, nutrition et al.
You go and start a compost heap from scraps of green kitchen waste.
Then one day you suddenly discover its teaming with red worms.
How did the find it?

Seeming devoid-but full of life.
They did not all arrive simultaneously. A few worms underground within a few
feet of the compost moved in and multiplied in this nice nutritious
environment.
