Microbial Genomes That Drive Earth’s Biogeochemical Cycles
Biogeochemical cycle: the combined movement, by biology and geology, of chemical elements between Earth’s biosphere and its abiotic reservoirs. Especially important are those involving the main building blocks of life: carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
A network of biotic and abiotic mechanisms maintains global elemental cycling, also called biogeochemistry. An important step in understanding global elemental cycling is determining the role of organisms and their communities in these processes. At the interaction of the living and nonliving world, life is powered by coupling its endergonic reactions to favorable electron-transfer reactions, changing the environment in the process.
