Soil and Decomposition – Basic Principles
How it works
Soil is the upper layer of the Earth's crust and consists of mineral components, organic material, water, and air. Decomposition is the biological process in which dead organic substances are broken down by soil organisms such as bacteria, fungi, and earthworms. This produces nutrients that plants can absorb. Soil provides a habitat for many organisms and is essential for plant growth. The composition of the soil influences its fertility and the rate of decomposition.
Note
Soil consists of mineral and organic components; decomposition converts organic material into nutrients through soil organisms that plants can use.

An example
What role do earthworms play in soil?
Earthworms loosen the soil and promote decomposition by eating and breaking up organic material. This improves soil structure and nutrient availability.
