Topsoil
Topsoil explained in an easy to understand way:
Imagine trying to find a book in a large, cluttered library where everything is stacked randomly. Just like you need to sift through the top layers of books to find the one you're looking for, plants rely on topsoil as the initial layer they interact with to access nutrients. The topsoil is like the top layer of that cluttered library; it's where all the essential materials are found, enabling plants to grow and thrive, much like finding that important book allows you to gain knowledge.
