- Nitrogen fixation: Bacteria convert atmospheric nitrogen into ammonia.
- Nitrification: Ammonia is converted into nitrites and then nitrates by nitrifying bacteria.
- Assimilation: Plants and other organisms take up nitrates to build proteins and nucleic acids.
- Ammonification: Decomposers break down organic matter releasing ammonia back into the soil.
- Denitrification: Denitrifying bacteria convert nitrates back into atmospheric nitrogen, completing the cycle.

Outline the major steps in the nitrogyn cycle?
The nitrogen cycle involves several key steps: nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium to nitrite, and then nitrate by bacteria), assimilation (incorporation of nitrogen into plant and animal tissues), ammonification (conversion of organic nitrogen into ammonium), and denitrification (conversion of nitrate back into atmospheric nitrogen by bacteria). These processes help maintain a balance of nitrogen in ecosystems.
Has five steps nitrogen fixation nitrification assimilation ammonification and denitrification?
Nitrogen fixation is the process where nitrogen gas in the atmosphere is converted into a form that organisms can use. Nitrification involves the conversion of ammonium to nitrate by bacteria. Assimilation is the process by which plants and animals incorporate nitrate and ammonium into their tissues. Ammonification is the breakdown of organic nitrogen into ammonium by decomposers. Denitrification is the process by which nitrogen in the form of nitrate is converted back into nitrogen gas by bacteria.
What is the process that converts ammonia into nitrates?
The process that converts ammonia into nitrates is called nitrification. It involves two steps: first, ammonia is oxidized by bacteria into nitrites, and then the nitrites are further oxidized into nitrates by another group of bacteria. This process is important in the nitrogen cycle as it makes nitrogen available to plants for growth.
Why don't the steps in a cycle always happen in the same order?
The steps in a cycle may not always happen in the same order due to variations in external factors or inputs that can alter the sequence of events. Additionally, feedback loops within the cycle can cause changes to the order of steps as the system adapts to different conditions. Flexibility in the cycle allows for adaptation and response to changing environments.
The process where ammonia is converted to nitrite and then nitrate?
This process is known as nitrification and occurs in two steps. First, ammonia (NH3) is oxidized to nitrite (NO2-) by specific bacteria. Then, a different group of bacteria converts nitrite into nitrate (NO3-). Nitrification is an essential part of the nitrogen cycle in the environment.

These processes help maintain a balance of nitrogen in ecosystems.
What are the steps in nitrogen cycle?
nitrogen fixation, denitrification, nitrification, amonification are the for steps of the nitrogen cycle.
How long does the Nitrogen cycle last?
The nitrogen cycle is ongoing and does not have a fixed duration. It is a continuous process in which nitrogen is converted between various forms by different microorganisms in the environment. The cycle involves steps such as nitrogen fixation, nitrification, assimilation, and denitrification, all of which occur at different rates and time frames depending on the environment and conditions.
What is the cyle in which matter and energy move through various steps on earth?
The cycle in which matter and energy move through various steps on Earth is known as the biogeochemical cycle. This includes processes such as the carbon cycle, nitrogen cycle, and water cycle, where elements and compounds are exchanged between living organisms, the atmosphere, water bodies, and the Earth's crust. These cycles are essential for sustaining life on our planet.
Soil bacteria are responsible for carrying many steps in the nitrogen cycle. Soil bacteria are NOT responsible for?
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
Which three major big steps make up the water cycle?
evaporation, condensation, and precipitation.
What are the 4 steps of the nutrient cycle?
1. Nitrogen molecules are split apart 2. Nitrogen moves from soil to plant material 3. Dead animals decompose 4. Gaseous nitrogen released
Has five steps nitrogen fixation nitrification assimilation ammonification and denitrification?

Assimilation is the process by which plants and animals incorporate nitrate and ammonium into their tissues. Ammonification is the breakdown of organic nitrogen into ammonium by decomposers. Denitrification is the process by which nitrogen in the form of nitrate is converted back into nitrogen gas by bacteria.
How is precipitation in the water cycle?
All major steps in the water cycle are important, otherwise the cycle breaks down. Precipitation is one of the two basic steps in the water cycle:Water rises into the atmosphere (evaporation, transpiration, evapotranspiration, sublimation).Water falls from the atmosphere (precipitation).
What is an action paln?
Outline of steps to achieve a goal.
Why is the carbon nitrogen cycle called cycle?
That's a rather nonsensical question; e.g. why is the world so complex? To be honest, the nitrogen cycle is not very complex, just requires some understanding. I recommend reviewing diagrams and attempt to embody a full understanding on the main processes, e.g. nitrogen fixation (biotic and industrial), nitrification, denitrification and putrefaction. And finally, I recommend finding a good diagram; all too often, I find myself wishing there were better quality nitrogen cycle diagrammatical searches found; try a reasonable college site.
Livestock farming creates large amounts of animal waste How would this affect the nitrogen cycle?
Livestock farming contributes to an increase in nitrogen inputs into the environment through animal waste, which contains high levels of nitrogen compounds such as urea and ammonia. This excess nitrogen can lead to eutrophication in water bodies as it promotes algal blooms and depletes oxygen levels, harming aquatic ecosystems. Additionally, the decomposition of animal waste releases nitrogen oxides into the atmosphere, contributing to air pollution and acid rain. Overall, the increased nitrogen from livestock farming can disrupt the natural balance of the nitrogen cycle, leading to environmental degradation.
