The order in which toxic nitrogen compounds are converted to less toxic nitrogen compounds in the nitrogen cycle is NH3 ----> NO2- -----> NO3-
The nitrogen cycle refers to the movement of nitrogen in the ecosystem. The process of converting nitrogen into less toxic forms of nitrogen which is useful to plants is called nitrification.
During the process of nitrification, ammonia or ammonium is first converted to nitrates by the action of the microorganism called nitrosomonas. Nitrobacter converts nitrites to nitrates which are useful to plants.
Hence, the order in which toxic nitrogen compounds are converted to less toxic nitrogen compounds in the nitrogen cycle is NH3 ----> NO2- -----> NO3-
