Answers

Answer 1

Answer:

Answer: E- Primary Layer

Explanation:

The definition of the Primary Layer, AKA Top soil, literally means the top layer of soil. This translates directly to the layer of soil with minerals and organic material.

Answer 2

Answer:

Final answer:

The A horizon in the soil profile is the layer that contains a mixture of minerals and organic material. Part of this organic material is humus, which enriches the soil with nutrients, making it fertile for plant growth.

Explanation:

In the context of soil profile, the A horizon is the layer that is a mixture of organic material and minerals. This includes the inorganic material of soil, which is made up of rock that has slowly degraded into smaller particles that vary in size, known as sand, silt, and loam. The organic matter that is mixed within this horizon is known as humus. Humus, which comprises microorganisms both dead and alive, as well as decomposing animals and plants, contributes greatly to improving the soil structure by providing plants with water and minerals. Therefore, the answer to your question is b) A horizon.
