Nitrogen Cycle

The nitrogen cycle starts off with the fish eating their food. The fish then produce carbon dioxide and ammonia. While the carbon dioxide goes to plants and the atmosphere, the ammonia gose to the nitrosomonas bacteria which turns it into nitrites. The nitrites then go to the nitrobacter bacteria to be turned into nitrates which is then removed from the ecosystem by plants and water changes.

Each of these parts are a very important part of the cycle. Without any of them the cycle would not be complete, especially without the fish because they start the cycle. Without plants and water's contact with the atmosphere there would be a high carbon dioxide concentration in the ecosystem. Without nitrosomonas there would be high ammonia levels with would kill the fish. Without nitrobacter there would be high levels of nitrites which would also kill the fish. And finally, without plants and water changes all of these chemicals would be in high amounts which would be good for nothing.
