sub soil
Most organisms in soil are found in the top layer of soil, known as the O horizon (organic matter horizon) or the A horizon (topsoil). This layer is rich in organic matter, nutrients, and microorganisms that support plant growth and decomposition processes.
The topsoil horizon (A horizon) contains the most living things in soil, including microorganisms like bacteria, fungi, and actinomycetes, as well as larger organisms such as earthworms, insects, and plant roots. These organisms play a crucial role in soil health and nutrient cycling.
The A horizon is the topsoil layer in a soil profile, characterized by high organic matter content and dark color due to decomposition of plant material. It is the layer where most plant roots and soil organisms are found, making it important for nutrient cycling and plant growth.
Topsoil is found in the uppermost layer of soil, typically the top two to eight inches. It is rich in organic matter and nutrients, making it essential for plant growth. Topsoil is where many plant roots grow and where soil organisms such as earthworms and bacteria are most active.
Soil horizons consist of different layers with unique characteristics: O horizon: Organic matter such as leaf litter and decaying plant material. A horizon: Topsoil rich in organic matter, minerals, and living organisms. B horizon: Subsoil with enriched minerals leached from above. C horizon: Weathered parent material that has not undergone much alteration.

no it is found in the topsoil or a horizon
Partially weathered parent material is found in the C horizon of a soil profile.
Partially weathered parent material is found in the C horizon of a soil profile.
The A horizon.
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.

The top layer of soil, known as the organic horizon or O horizon, contains the most decayed organic material. This layer consists of partially decomposed plant and animal matter, such as leaves, twigs, and dead organisms.
it is the deepest soil found and is below horizon a and b
