Question

The image shows a soil horizon with its layers labeled. Which layer is nutrient rich and contains a mixture of humus, clay, and important minerals?

Answer 1

The Topsoil layer.

Step-by-step 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.
