How is the circulation of substances in the biosphere?

The circulation of substances in the biosphere follows a fairly simple principle. There are animals and plants, they are composed of various organic components. During life, these organisms accumulate various substances. For example, a cow eats grass and assimilates fiber, vitamins and other components in her body. Some of the processed substances enter the soil along with the waste products of the cow and, as a result of the processes of mineralization and humification, these substances affect the development of plants. These same plants can then become food for other animals. All living things still die and are again fed to the processes of humification and mineralization.
