Talk to a group of carbon scientists and they will probably tell you that of all the elements, carbon makes the world go round. But all living things also depend on nitrogen, as well as carbon, to survive. Like carbon, nitrogen has a biogeochemical cycle that shuttles the element between the deep Earth, oceans, and atmosphere, but details of that cycle are poorly understood.
