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-

Answer:
A terrarium with a plant and a snail
Explanation:
This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.
Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.
