Sagot :

Answer:

The Topsoil layer.

Explanation:

The topsoil layer is a mixture of sand, silt, clay, and broken down organic matter, called humus. Humus is a rich, highly decomposed organic matter mostly made from dead plants, crunched-up leaves, dead insects, and twigs. Topsoil is the home of living things and the materials that they make or they change.
