Soil organisms make up the diversity of life in the soil (Figure A1.1). soil provides shelters for many animal types, from invertebrates such as worms and insects up to mammals like rabbits, moles, foxes and badgers. 1 Some soil organisms cause rots, some release substances that inhibit plant growth, and others are hosts for organisms that cause animal diseases. Soil bacteria and soil fungi are the start of the soil food web that supports other soil organisms and the functions of a healthy soil. It is widely assumed that low plant species diversity renders agroecosystems vulnerable to harmful soil organisms by reducing overall antagonisms. Living organisms – earthworms, beetles, fungi, bacteria. with the micro-with the micro- carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.
