20.4: The Nitrogen Cycle
Figure 20.4.2 20.4. 2: In the nitrogen cycle, nitrogen-fixing bacteria in the soil or legume root nodules convert nitrogen gas (N 2) from the atmosphere to ammonium (NH 4+ ). Nitrification occurs when bacteria convert ammonium to nitrites (NO 2-) and then to nitrates (NO 3- ). Nitrates re-enter the atmosphere as nitrogen gas through ...
The Nitrogen Cycle: Understanding The Process of a …
The Nitrogen Cycle: Nitrosomonas. Ammonia is broken down by beneficial bacteria or Nitrosomonas, oxygen-loving bacteria! It takes around 6 to 10 weeks for your pond to develop its own beneficial bacteria. A new pond can go through a rising ammonia cycle, this can be shortened by purchasing.
Nitrogen Cycle In Aquariums
The nitrogen cycle is the process by which certain bacteria process harmful waste. There are three stages to the cycle: 1. Waste Products Decay. The first stage in the nitrogen cycle is the decay of organic matter, such as uneaten food, dead plant leaves, dead organisms, and the waste produced by fish and invertebrates.
The Nitrogen Cycle Lesson for Kids | Study
We will follow the cycle to understand how this happens. Create an account Table of Contents ... If the bacteria cycles the nitrogen from the air into usable forms in the soil, then plants can ...
Nitrogen Cycle
The nitrogen cycle is a biogeochemical cycle that converts nitrogen into various forms throughout the ecosystem. Nitrogen is an essential element for life that …
The Aquarium Nitrogen Cycle
Here's the aquarium nitrogen cycle process summarized in 5 steps: Fish poops in the water. Fish poop and other organic matter release ammonia. Beneficial bacteria grow and convert ammonia to nitrite. A different kind of beneficial bacteria converts nitrite to nitrate. You remove nitrates with water changes and plants.
Nitrogen cycle | Definition & Steps | Britannica
nitrogen cycle, circulation of nitrogen in various forms through nature. Nitrogen, a component of proteins and nucleic acids, is essential to life on Earth. Although 78 percent by volume of the atmosphere is nitrogen gas, this abundant reservoir exists in a form unusable by most organisms. Through a series of microbial transformations, …

Intro to biogeochemical cycles (article) | Khan Academy
The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
What Is the Nitrogen Cycle and Why Is It Key to Life?
Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a ...
The Nitrogen Cycle Through Nature
Nitrogen Cycle. Understand Nitrogen's Cycle Through Nature. The nitrogen cycle describes the path of the element nitrogen through nature. Nitrogen is essential for life—it is found in amino acids, proteins, and genetic material. Nitrogen is also the most abundant element in the atmosphere (~78%). However, gaseous nitrogen …
Understanding Nitrogen Cycle with a Diagram
Nitrogen Mineralization. Also known as ammonification, the organic form of nitrogen from the animal wastes, dead and decayed living organisms is converted into inorganic form. In this nitrogen cycle step, decomposers (bacteria and fungi) act on the decayed organic matter containing nitrogen and convert it into ammonium (NH4+).
Nitrogen Basics – The Nitrogen Cycle
Nitrogen Cycle. The N cycle illustrates how N from manure, fertilizers and plants moves through the soil to crops, water and the air. Understanding the N cycle will help you make the best use of manure and fertilizers to meet crop needs while safeguarding the environment. In general, the N cycle processes of fixation, mineralization and ...
Nitrogen Cycle
Understanding the complex fluxes in the nitrogen cycle is crucial because nitrogen can limit primary production in lakes, streams, wetlands, groundwaters, riparian zones, and marine habitats. In addition, nitrate and nitrite can be toxic ( Highlight 14.1 ) and understanding the nitrogen fluxes and factors controlling them may allow for ...
