nitrogen cycle summary
using words and diagrams, describe the nitrogen cycle, including what happens, why it’s important, and what the major components are.

Explanation:

The nitrogen cycle is a biogeochemical cycle. Nitrogen in the atmosphere is converted to ammonia by nitrogen - fixing bacteria (nitrogen fixation). Ammonia is then converted to nitrites and nitrates (nitrification). Plants take up these nitrates and use them for growth. Animals eat plants and obtain nitrogen. When plants and animals die, decomposers break them down, releasing ammonia back into the soil (ammonification). Some nitrates are converted back to nitrogen gas (denitrification) and returned to the atmosphere. It is important as nitrogen is a key component of amino - acids, proteins, and nucleic acids, essential for life. Major components include nitrogen - fixing bacteria, nitrifying bacteria, decomposers, plants, and animals. A simple diagram could show the atmosphere, soil, plants, animals, and arrows indicating the flow of nitrogen between them.

Answer:

The nitrogen cycle involves nitrogen fixation, nitrification, ammonification, and denitrification. It is crucial for life as nitrogen is essential for biological molecules. Major components are nitrogen - fixing bacteria, nitrifying bacteria, decomposers, plants, and animals.
