topsoil
The Rigolirh, the roots are found in the Bedrock.
No, bedrock is not the part of soil that consists of decaying organic matter.Specifically, bedrock comprises one of six soil horizons or layers. Organic animal and plant matter decompose in the topmost layer and supply the layer immediately below with the humus content of A horizon's humus-mineral mix. Bedrock is found in sixth, bottommost layer which includes unweathered rock.
The O horizon contains the most organic matter in a soil profile. It is the top layer of organic material such as decaying leaves, branches, and other plant debris that is actively decomposing. The A horizon, also known as the topsoil, is a layer rich in minerals and organic matter that is developed from the decomposition of plant material in the O horizon.
Biosphere
The uppermost layer of the soil which is the O-horizon, and is called "Humus".
the layer the contain the richest material is the top soil :)
the top one
When leaves and other organic matter lie on the forest floor, they begin to decompose. This layer of decomposing organic material is called litter.
An atmospheric layer that contains layer is stratosphere. It contains ozone layer.
the layer of mud under the layer of decaying leaves
the O-Horizon is the topmost soil so it has the most humus
The cerebral cortex contains the bodies of neurons which appear grey (grey matter). The layer under the cortex contains myelinated axons (white matter).
