What is the ‘point’ of earthworms? If they all disappeared tomorrow, would there be any impact? (Other than a food source loss for some animals)

Question

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

Worm poops.

Plant eats worm poop.

Plant puts nitrogen from worm poop into leaves.

PHOTOSYNTHESIS!
