Nitrogen cycle in aquariums

When an aquarium is cycled, there are colonies of beneficial bacteria established that help to filter waste and toxic compounds. 

Ammonia and nitrite are very harmful, but they will naturally occur when a fish is present (through fish food and waste). This is why it's important that there are enough bacteria established that can quickly consume and convert ammonia and nitrite.

In a cycled aquarium, ammonia and nitrite levels should be 0 and nitrate levels should be low. Regular water changes are still necessary for removing excess nitrates and maintaining water quality.

The process of cycling an aquarium can take several weeks before it is safe to add fish.

What is the Importance of Nitrogen Cycle? 

The Nitrogen cycle is defined as the biogeochemical cycle process that involves transforming the inert nitrogen that is available in the atmosphere, into a more usable or conventional form, that can be actively used by plants, and various living organisms. 

Moreover, the nitrogen cycle as said above involves multiple processes such as putrefaction, denitrification, nitrification, nitrogen fixation, and decay. Besides, nitrogen exists in two forms in nature, sustainable or organic nitrogen, and inorganic nitrogen. Furthermore, the inorganic nitrogen in the atmosphere is more abundant compared to organic nitrogen. And because of the Nitrogen cycle, the abundant inorganic nitrogen is converted into organic nitrogen and it is passed up into the food chain to balance the ecosystem. 

Importance of Nitrogen Cycle 

From the above description, you can guess, that the nitrogen cycle is very important. And here in this section, we will list some of its significance or contributions to the ecosystem. 

As we begin to narrate the importance of the nitrogen cycle, the first point that has to be essentially noted is that the nitrogen cycle causes biochemical processes, which help inert nitrogen gas to get converted into a usable form for plants. 

Nitrogen is a very crucial part of the cell, as it is an important component in the formation of various biomolecules. 

The Photosynthesis process in plants involved chlorophyll, is possible only because of the nitrogen compounds. 

Moreover, the nitrogen cycle also causes the ammonification process, which involves bacteria that converts animal and plant platter, through decomposition. 

Due to the nitrogen cycle, nitrates and nitrites are released into the soil, which will boost productivity of the soil. 

As per the importance of the nitrogen cycle, let us note that activities, such as fuel combustion, and the use of fertilizers with nitrogen content also lead to the cycling of nitrogen. In these cases, nitrogen-holding compounds increase in their levels in the atmosphere. As nitrogen converts itself into compounds, its abundance in the atmosphere can be effectively harnessed. Because plants use nitrogen compounds immensely. 

Stages of Nitrogen Cycle 

As explained above, there are multiple stages in the Nitrogen Cycle, which we are going to explain briefly here in this section.  

Nitrogen Fixation Process 

Nitrogen fixation is the first step in the nitrogen cycle. This process takes multiple steps, First, the conversion of atmospheric nitrogen (N2) into inert form, which is then converted into Ammonia (NH3). By the end of this process, the nitrogen is deposited into the soil and surface waters, mainly by precipitation. Moreover, the nitrogen fixation process is possible only because of a symbiotic bacteria called Diazotrophs. Aside from these various other bacteria like Rhizobium and Azotobacter can also be used in this process. As explained, these bacteria are stored in the roots of the leguminous plants and they aid in converting inert nitrogen into ammonia. Apart from this, lightning and artificial methods can also be used for the nitrogen fixation process.  Some of the ways in which nitrogen fixation can happen is atmospheric fixation features lightning, artificial, and mostly the industrial way of fixation where ammonia is processed or manufactured at high temperatures and pressure  This forms the prelude in understanding the importance of the nitrogen cycle. 

Nitrification 

The nitrification happens in two steps. The ammonia deposited into the earth’s atmosphere is converted into nitrate with the help of the bacteria in the soil. Now the nitrites formed are transformed into the oxidation of the ammonia process, with the help of Nitrosomonas bacteria species. Then Nitrobacter is used to convert the nitrites into nitrates. The bacteria get energy with this transformation. 

2NH3 + 3O2 → 2NO2– + 2H+ + 2H2O  

2NO2– + O2 → 2NO3–  

Assimilation 

This is the process that explains how plants absorb nitrogen from the roots. The Nitrates, Nitrites, and ammonium compounds enter the plants through the soil and help them develop, grow, and evolve. In this way, these components make their way into the food chain. 

Ammonification 

All the plants and animals when they die, undergo a decomposition process, that releases ammonium gas into the atmosphere. However, this process is possible only because of the virus and bacteria present in the soil. 

Denitrification 

This is known as the reverse process of nitrification, and it occurs in the deeper crests of the soil where bacteria convert NO3- to N2 and other gaseous compounds such as NO2.  After a point of time, the nitrogen components in the plants and soil ecosystems are transferred back into the air through the denitrification process. This method involves converting nitrate (NO3-) into Nitrogen in the gaseous form. However, one thing the students must remember is that there is no oxygen present during this process. 

In the above article, we have provided comprehensive information about the nitrogen cycle, the stages of the nitrogen cycle, the importance of the nitrogen cycle, and many more. If you are studying similar complex topics in Biology, and have any issues understanding it, then it would be better to join the online coaching classes.

Nitrogen Cycle

The Nitrogen Cycle should be something we are all familiar with, but nitrogen is a key component when it comes to plant life. Without nitrogen, the plant's growth will be stunted, and produce much smaller fruits or flowers if produced at all. All fertilizers used are riddled with nitrogen in order to give the soil enough for the plants to have an adequate yield. However, it’s imperative that the right amount is calculated for the plants, otherwise runoff with excess nitrogen can be destructive to certain habitats. Nitrogen is often considered the “key” to life because it is important to the makeup of the nucleic acids that make up our DNA and RNA. The first step in the Nitrogen cycle is the fixation of nitrogen, or the movement of Nitrogen gas from the atmosphere to the soil. Energy is required to make nitrogen gas available for plant absorption, this can be done by intense pressure and heat, but it is most commonly done within the soil by nitrogen fixing bacteria. The same process is synthesized in aquaponics from my earlier post. The second step is mineralization, this occurs in the soil and is when microbes fix nitrogen from decomposed material or manure that can be used by plants once more, this often results in excess ammonia. The third step is nitrification, which also occurs within the soil. This is where the ammonia created from mineralization is converted to nitrites and nitrates, nitrites will eventually be converted to nitrates by more nitrogen fixing bacteria but the nitrates are directly edible for plants and will be used as food. The last step is denitrification, where bacteria convert nitrates into nitrogen gas which is released back into the atmosphere.

New aquariums need time to establish colonies of beneficial bacteria that will convert toxic compounds like ammonia and nitrite into less harmful compounds like nitrate.

When you add a fish to a tank, its waste and uneaten food break down into ammonia. If the aquarium is not cycled, there will not be enough bacteria to break down ammonia fast enough, and toxins will build up which is stressful and can even be fatal for fish.

This is often called “new tank syndrome” and can happen when fish are added to uncycled aquariums. It can take several weeks to cycle an aquarium before it is safe to add fish.

NITROGEN CYCLE: A Biogeochemical  Analysis—Diazotrophic Nitrate

| OUTLINE | Hilary Keller | OBSERVING THE NITROGEN CYCLE | KEYWORDS | Nitrogen-fixing, decomposition, nitrification and denitrification.   Iron is most often found in the Fe(II) state. Mainly iron exist in 2 oxidation states; Fe(II) is known as ferrous while Fe(III) is known as ferric. That said, Iron ("Fe2+"=, ferrous ion) is a necessary trace element used by every single living organism.   "Work previously by Garrels and Thompson, who investigated the anaerobic oxidation rate suggested the rate-controlling mechanism corresponds to the absorption of ferric and ferrous iron on the pyrite surface. The rate oxidation-reduction potentiality of the solution that is independent of the total iron concentration is within a range that could be examined. Their conclusions are valid; however, neither conclusion is correct."    Indirect oxidation occurs by oxidation of pyrite by ferric ions, the ferric ions being generated by bacterial oxidation of ferrous ions in solution. The bacteria oxidize iron in solution to 70 or 80% ferric. This finding is significant to the fertilizer/soil ammonia Ph equilibrium.    "Direct oxidation implies the oxidation of pyrite." Fourteen mols of ferric ion. Undetermined consummation of oxygen to oxidize one mole of pyrite. Rates are thereby calculated in terms of micromoles of pyrite oxidization per/hour = (singular) gram of pyrite.

(via Carbon Cycle & Nitrogen Cycle – Biogeochemical Cycles of Nature)

Cycles mean there is a continuous exchange of elements between air, water, plants and animals. It is through these natural cycles that planet Earth is able new itself.

We have living things and we have non-living things. There is an interaction that happens between the living things and also between the living and non-living things. All together they form an ecological unit that is self-contained and self-sustaining.

They contain the resources to regenerate themselves. There are different such cycles in our nature and we are here talking of two such important cycles namely as carbon cycle and nitrogen cycle.

The carbon cycle includes the uptake of carbon dioxide by plants for the process termed as photosynthesis. The nitrogen cycle involves the uptake of nitrogen from the atmosphere by a process called as fixation.
