Title says it all, is the organic part of our planet’s ground, the dirt/soil all of biological origin be it leaves or waste or flesh of plants and animals over many many many years? Or are there other ways some is formed through geological methods?
In: 1
rocks are broken down by various processes and become available minerals for life constantly, the dead bodies of lifeforms become rocks by various processes too. Some early life ate rocks slowly and a huge unseen world of bacteria and archaea has continued to do just that for 3.5 billion years or so. The deep biosphere contains more mass of life than the ocean.
