Study of chemical processes caused by organisms in geologic media and how elements are cycled.
an Earth system science that encompasses the biological, geological, and chemical processes and examines the interactions between them.
Study of microbially mediated chemical transformations of geochemical interest, e.g. nitrogen or sulfur cycling.
scientific study of the interactions among the biological, geological, and chemical systems of Earth, including the cycling of matter and energy through them; biogeochemical (adverb).
The study of biogeochemical cycling.
The field of biogeochemistry involves scientific study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere), and the cycles of matter and energy that transport the Earth's chemical components in time and space. Biogeochemistry is a systems science.
