Biogeochemistry

Biogeochemistry is the branch of science which studies the chemical and biological processes in natural environments and the cycling of matter between living and non-living components of the environment. It studies how elements move from the atmosphere, soils, and oceans, to plants and animals, and back. Biogeochemical cycling is the transfer of essential elements such as carbon, oxygen, and nitrogen through ecosystems, and it is essential to the functioning of Earth's ecosystems. Biogeochemistry has tremendous practical significance, as it helps to understand how climate change and pollution affect natural systems, and how nutrient management strategies can improve the productivity of agricultural land. Additionally, biogeochemical research can inform efforts to conserve fragile and endangered species.
