What Does an Earthworm Eat?

He became excited as if he had solved an unsolved mystery of the world, "An earthworm definitely eats dirt! Look, some insects like to eat leaves, and some like to eat other insects. But an earthworm doesn't have a big mouth, so it definitely can't eat other insects. There are no leaves in the soil, only soil, so it definitely eats soil!"

After saying that, he looked at Xiao Ye. "Xiao Ye, you're a scholar. You're more knowledgeable than your brothers, so you must know more. Don't you think Grandpa is right?"

Xiao Ye hesitated for a long time with a conflicted face. He did not know what the earthworm ate, and the book did not say anything about it.

It was best if he said honestly, "Grandpa, I don't know either. Teacher didn't say anything."

Old Man Jian immediately glared at him and muttered, "What kind of school are you in? They don't even teach this?"
