Question

horizons
the o horizon contains leaf litter and other decaying organic material lying on the surface of the soil. it is located in the diagram at choose your answer. the transition layer or c horizon is made up of partially weathered parent material with little or no organic matter. it is located in the diagram at choose your answer. the subsoil layer is usually light in color and low in organic matter. due to leaching, this layer is rich in minerals. this layer is located in the diagram at choose your answer. the layer that is dark because it contains decomposers and is rich in humus or organic matter is at number 2. this layer is called choose your answer. the layer of unweathered solid rock called bedrock is at this location in the diagram choose your answer.

Explanation:

1. O horizon location

The O horizon (organic layer with leaf litter and decaying matter) is on the soil surface. In the diagram, the topmost layer (number 1) has grass and is the surface, so O horizon is at 1.

The C horizon (partially weathered parent material, little organic matter) is deeper, often below subsoil. In the diagram, layer 4 or 5? Wait, the C horizon is typically below B (subsoil) and A (topsoil). Wait, the description: "partially weathered parent material with little or no organic matter" – the C horizon is at layer 4? Wait no, the diagram: layer 5 looks like bedrock? Wait, no, the layers: 1 (O), 2 (A? dark with organic), 3 (B? subsoil), 4 (C? partially weathered), 5 (bedrock). Wait the text says "transition layer or C Horizon is made up of partially weathered parent material" – so C horizon is at 4? Wait no, let's recheck. The O is 1, then A (2, dark with organic), B (3, subsoil, light, low organic), C (4, partially weathered), 5 (bedrock). So the transition/C horizon (partially weathered) is at 4? Wait the question says "located in the diagram at" – so answer 4? Wait no, maybe 4? Wait the text: "The transition layer or C Horizon is made up of partially weathered parent material with little or no organic matter. It is located in the diagram at" – so looking at the diagram, layer 4? Or 5? Wait 5 is bedrock (unweathered), so C is 4. So answer 4.

Subsoil (B horizon) is usually light in color, low in organic matter, below A. In the diagram, layer 3? Wait the text: "The subsoil layer is usually light in color and low in organic matter. Due to leaching, this layer is rich in minerals. This layer is located in the diagram at" – subsoil (B) is layer 3. So answer 3.
