As above. Sorry if this is a silly question!
I realise there is no ‘point’ to any particular animal or plant, but you often find that various species provide some sort of benefit (e.g. plants giving out oxygen, those birds that clean crocodiles’ teeth, spiders eat a lot of flies).
I just wondered if worms are particularly ‘useful’, because they don’t seem to do much from what I can tell

Worms are basically tiny wood chippers that go around blending up anything that gets scooped into them and spitting out (most of) it. Worms eat all of the leaves and stuff and help break it down into dirt. Fungus and bacteria do the same thing, but at a slower rate. These piles of leaves served as homes to bugs, lizards, frogs, spiders, etc and gave protection for a lot of seeds and plants growing under it. The America’s lost all of their worms in the last ice age and forests adapted to not having them. Since they’ve been brought back, forests have adapted back to having them. Worms don’t do anything crazy, but do affect biodiversity. Having them all disappear would really just make us upset that there’s leaves everywhere
