The Role of Biology in the Climate System: Long Term Climate Regulation Earth History, Gaia and Human Perturbations of Biological Systems. Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties.It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans. iv) Microorganisms are used for making medicines. Some agar media contain extracts at concentrations of 10 to 50% of the total liquid volume. However, soil organisms are involved in most soil processes, and soils cannot function naturally without the presence of life.
