Scientists have discovered that marine diatoms, tiny phytoplankton abundant in the sea, have an animal-like urea cycle, and that this cycle enables the diatoms to efficiently use carbon and nitrogen from their environment. The research team believes that the cycle could be a reason for the domination of diatoms in marine environments, especially after upwelling events -- the upward movement of nutrient rich waters from the deep ocean to the surface.
