About This Root

From Greek bios (life, way of living). One of the most recognizable scientific roots — biology (study of life), biography (writing of a life), biodiversity (variety of life), antibiotic (against life/bacteria), and symbiosis (living together). The biotic/abiotic pair distinguishes living from non-living in ecology.
