A compost pile (detritus, plant matter), with the help of worms, turns into dirt.

That's actually a very difficult question. In the context if worms and the ops post I think the best definition would be one of energy availability. Detritus would have lower entropy allowing the worms to more easily extract energy. Dirt would have a much higher entropy as many of the complex molecules in the detritus have been broken down into more smaller fragments.

Well, now that I’ve reviewed up the definition of detritus, not a whole lot.
😂 I would say that detritus is coarser and implies the sense being recognizeable as having been part of a larger whole.
I meant it in the sense of organic debris: leaf litter and such. I think of dirt as being finer and relatively uniform. Water + dirt = mud. Water + detritus = clean detritus.

What I meant was that worms sustain themselves on organic material, and, after they break it down, it is more incorporated in to the soil.

Theres is a whole other discussion to be had whether dirt ≈ soil…

I'll take a shot. "Detritus" is the easier part: it's decaying plant and animal matter. So the worms are eating leaves and stuff after it's started breaking down.

"Dirt" is a little more difficult because it doesn't have as crisp of a definition. Usually when people say "dirt" in this context, they mean "soil," but that's only a little better. The relevant definition for soil is, "the upper layer of earth that may be dug or plowed and in which plants grow."

That detritus gets broken down by bacteria and becomes soil even without worms, but worms do basically the same thing faster. Plus their moving around helps loosen the soil, which also is helpful for growing plants.

what is the difference between detritus and dirt?

They're pretty similar but it seems:

Detritus - fragments of materials that have disintegrated or worn away.

Dirt - Unclean matter, soil or grime.

Close because I'm pretty sure soil is broken down rocks and stuff.

More available/easily digestible nutrients probably. Stuff like decomposing leaf litter, dead plants, other animal excrement.
