Summary Introduction
To determine: The three reasons which show the importance of soil organic matter (SOM).
Introduction: Soil is the uppermost layer of the earth’s surface. It has a complex composition of a variety of minerals, nutrients, organic matter, and non-organic compounds. It provides habitat for a variety of microorganisms. Soil organic matter is the indicator of organic content in the soil.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
