Domesticated animals play a significant role in providing high-protein food worldwide. Even zooplankton, which is a microscopic form of fauna, is a key source of nourishment for marine life in the food chain. Soil Resources Soils are a combination organic and inorganic life. It is comprised of three components. Physical and chemical weathering are responsible for the production of inorganic or mineral matter.
Organic matter consists of dead macroscopic and microscopic forms of flora and fauna.
Water and gas in the pores between soil particles, and the living forms of soil fauna such as worms, insects and bacteria. The production of soil is a complex process involving weathering, water, air, macroscopic and microscopic plant and animal forms, The process also depends on temperature and moisture levels. More specifically, the production of soil from organic and inorganic materials at the upper portions of the mantle rock is comprised of four processes . Accumulation of Humus 2. These four processes can produce mature soils over thousands of years.
