...Dear lord.

Okay. Nitrogen (dinitrogen - N2) is the most abundant molecule in our atmosphere. However, since it has a bond order of three and very strong bonds at that, it is generally useless. There are certain organisms, called nitrogen - fixing bacteria, though, that can convert nitrogen to ammonia (NH3). Ammonia is usable by plants, who incorporate it into amino acids, etc. and nitrate (NO3-). When animals eat the plants, they use these prefabricated molecules for themselves. This travels up the food chain. Finally, when an animal dies, bacteria break down the fixed nitrogen back to N2 and the process starts all over again.

Are precipitation evaporation and condensation all important parts of the nitrogen cycle?

No, precipitation, evaporation, and condensation are not directly involved in the nitrogen cycle. The nitrogen cycle involves processes such as nitrogen fixation, nitrification, denitrification, and ammonification which are related to the cycling of nitrogen compounds in the environment.


What is the difference between nitrogen cycle and phosphorus cycle?

Nitrogen cycle is made up of nitrogen gas so when nitrogen gas and oxide compress they make a nitrogen cycle. With the phosphorus cycle it doesn't compress gas it just goes to gas to oxide making phosphorus cycle.


Is it true that the process of combining nitrogen with other elements in order to make usable compounds is called the nitrogen cycle?

No, the process of combining nitrogen with other elements to make usable compounds is not called the nitrogen cycle. The nitrogen cycle refers to the natural processes by which nitrogen is converted between its various chemical forms in the environment, including nitrogen fixation, nitrification, and denitrification.


What converts gaseous nitrogen into ammonia in the nitrogen cycle?

Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert gaseous nitrogen into ammonia through a process called nitrogen fixation. This process helps make nitrogen available to plants for growth and is a key step in the nitrogen cycle.


How is nitrogen cycle like water cycle?

Both the nitrogen cycle and water cycle involve the movement of a key substance through different forms and locations in the environment. In the water cycle, water is cycled through various processes like evaporation, condensation, and precipitation. Similarly, in the nitrogen cycle, nitrogen is cycled through processes like nitrogen fixation, nitrification, and denitrification. Both cycles are essential for maintaining ecosystem balance and supporting life on Earth.
