Earth's atmosphere contains about 78% nitrogen Plants cannot use nitrogen in its N2 form, so it must be transformed through a process

In National 4 Biology discover how atmospheric nitrogen is processed by bacteria, allowing plants and animals to build essential proteins  Nitrogen cycle Atmospheric nitrogen cannot be used directly by plants and animals Nitrogen

พงษ์ศักดิ์ Both the global and internal nitrogen cycles are biologically regulated, but the transformations are the result of biotic and abiotic interactions Electron The nitrogen cycle Nitrogen is cycled through air, water and soil, undergoing many transformations made possible by the actions of specialized bacteria The
