O Ciclo do Nitrogênio

Synopsis: In addition to videos and animations are used advanced features of interactivity for the user to understand, in a participatory and intuitive way, what factors are involved in the changes and environmental behavior. This feature, developed by the AEB School Program, defines the concept of nitrogen and the way it does in nature. We have also made an approach of how man's actions in the last century brought intense changes in the nitrogen cycle and how these changes may or may not have changed the balance.
