Quizplus · Accepted Answer

The A horizon is the topsoil layer, where organic matter accumulates and most biological activity occurs. The E horizon is a soil layer between the A and B horizons, which is typically lighter in color due to the loss of clay, iron, and other minerals. The C horizon is the layer of soil that lies beneath the B horizon and consists of partially weathered rock or mineral deposits. The O horizon is a surface layer of organic material, such as leaf litter, that accumulates in forested ecosystems. Therefore, minerals are primarily added to the B horizon from the A and E horizons, which have the greatest concentration of nutrients and minerals.
