Why do worms live underground?
In:
The environment can be seen to have “niches”, each animals lives in a “niche”. For example a monkey up a tree, a woodlouse under a log.
If multiple species occupy the same niche they will compete and that may lead to one going extinct.
It’s essentially a case of “why not?”. If it’s possible for organisms to survive somewhere, something will fill that niche. The more specific your niche the less competition.
They feed by ingesting soil, extracting vegetable mater from it and passing the rest through, throwing up “worm casts”. To do that they need to be underground, making tunnels as they go.
Assuming you mean earthworms, that’s where their food is. They eat organic material in soil. If they lived elsewhere, they’d die of starvation.
