What is incorrect in: "It's true that children depend in their parents for food, clothing and shelter."?

The sentence "It's true that children depend in their parents for food, clothing and shelter" contains an error with the preposition "in." The correct preposition to use in this context is "on." The phrase should read "depend on their parents," which reflects the relationship where children rely upon their parents for necessary resources like food, clothing, and shelter.

Using "in" would incorrectly suggest that the dependence occurs within the parents in some way, which is not the intended meaning. Prepositions are crucial in conveying the correct relationships between words in a sentence, and choosing the appropriate preposition clarifies the intended meaning.
