It is the O horizon. The A horizon is the mineral horizon and does include a large amount of organic material but the O horizon contains the most abundant amount of organic matter. The O horizon overlies the A horizon.
A scavenger is an animal that feeds on dead or decaying matter, helping to clean up the environment by recycling nutrients. Scavengers play a crucial role in ecosystems by breaking down organic material and returning nutrients back into the soil.
Mint and tree ear live together in a symbiotic relationship in nature. The mint plant provides shade and nutrients to the tree ear fungus, while the tree ear fungus helps the mint plant by breaking down dead organic matter in the soil. This relationship benefits both organisms by improving the overall health of the ecosystem they inhabit.
There are three types of persuasive speeches: 1) a persuasive speech on a factual matter, 2) a persuasive speech on an axiological matter (a matter of value) 3) a persuasive speech on a matter of policy.

Some reasons people may not vote include lack of interest or belief that their vote doesn't matter, feeling disenfranchised or disconnected from the political process, logistical barriers like lack of time or accessibility, or disillusionment with the available candidates or choices.
The C horizon does not typically contain organic matter, as it is primarily composed of weathered rock material. Instead, organic matter is more commonly found in the upper A horizon of the soil profile.
The topsoil is part of the A-horizon in the soil profile. This layer is typically dark in colour and rich in organic matter, making it fertile and ideal for plant growth.
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 of the soil profile consists of the O horizon (organic layer) followed by the A horizon (topsoil). The O horizon contains organic matter like leaf litter and decomposing plant material, while the A horizon is rich in minerals, nutrients, and organic material which supports plant growth.
The O horizon, also known as the organic horizon, contains the most organic material. It is made up of decomposing organic matter like leaves, plant debris, and other organic materials.
A horizon
Subsoil is typically found in the B-horizon of the soil profile. It is located below the topsoil layer (A-horizon) and contains less organic matter, more minerals, and is often denser than the surface soil.
The topsoil horizon (A horizon) typically contains the most organic matter in soil. This is where organic materials such as dead plants, roots, and other organic debris accumulate and decompose, enriching the soil with nutrients.
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decaying leaves and plant material. It is typically found at the surface of the soil profile.
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decomposing plant material and leaf litter. It is typically found at the surface of the soil profile.
Subsoil is typically found in the B horizon of the soil profile, situated below the topsoil (A horizon) and above the parent material (C horizon). The subsoil contains less organic matter and nutrients compared to the topsoil but often has mineral accumulation and deeper roots.
