(i) Soil is a mixture of small particles of rock.It contains bits of decayed living organisms known as humus. Microscopic life also exists. (ii) Type of soil is decided by average size of particles found in it and quality of the soil decided by the amount of humus and the microscopic organisms found in it.Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air.
