Nitrogen cycle. Atmospheric nitrogen cannot be used directly by plants and animals. Nitrogen needs to get converted to nitrogenous compounds. This process is called Nitrogen fixation.

NITROGEN CYCLE:Nitrogen is the important essential element for all living organisms by the synthesis of Amino acids, proteins, Enzymesetc.What happens if there is no Nitrogen?. Root systems and plant growth are stunted.Older leaves turn yellow.Decrease in crop production. Soil microorganisms life become dangerous.In Atmosphere its concentration is 78 percentage.The circulation or cyclic movement of Nitrogen from the atmosphere physical or abiotic component to soilBiotic componentand back into the atmosphere is known as.Nitrogen cycle involves various steps:1.Nitrogen fixation. 2.Nitrogen assimilation 3. Ammonification 4. Nitrification 5. Denitrification. Plants cannot utilize Atmospheric nitrogen so it should be converted into utilizable form such as Ammonia.1.Nitrogenfixation:This is the first step of Nitrogen fixation.Conversion of atmospheric nitrogen into Ammonia for living organismsis known as Nitrogen fixation.This process is carried out by leguminous plants such as ground nut; even some bacteriacan fix atmospheric nitrogen.Examples of bacteria --Azotobacter Clostridium, Rhizobium, Nostoc and Anabaena2.NitrogenAssimilation:The process of absorbing Nitrates and Ammonia into Organic nitrogen is known as Nitrogen Assimilation.This organic nitrogen is transferred into animal's body when plants are eaten by animals. 3. Ammonification:The process of converting organic nitrogen into Ammonia when Animals die is known as Ammonification.It is also known asMineralization.This process was carried out by some Saprophytes like Fungi andBacteria.Ammonia is also produced from volcanic eruptions and excretory products of Animals.4.Nitrification:The Bacteria which is involved in nitrification is known as Nitrifying bacteria.Ammonia is first converted to nitrites.Examples: Nitrosomonas,Nitrococcus.Nitrites are converted to nitratesExamples:Nitrobacter.5.Denitrification:Nitrates are converted into molecular nitrogen through Nitric oxide is known as Denitrification, in order to maintain the equilibrium of nitrogen in the atmosphere.Bacteria which are involved in denitrificationare known as denitrifying bacteria.Examples: Thiobacillusdenitrificans,Pseuodomonasdenitrificans and Micrococcusdenitrificans.Problems with increase of Nitrogen:Acid rain formation. Acidification of soil and lakes. Increase in death of plants.

How Do Humans Affect the Nitrogen Cycle?. Part of the series: Chemistry & Biology. The nitrogen cycle is the process and movement of nitrogen through ecosystems, and humans affect the nitrogen cycle through the use of fertilizers and chemical additives in soil, as well as through the burning of fossil fuels. Find out how humans have caused a decrease in soil nutrients with help from a science teacher and field biologist in this free video on chemistry.

Do you know that Plants cannot absorb nitrogen directly from the atmosphere.This nitrogen needs to be fixed first so that it can be used by plants and animals.In this short video, we learn that certain types of bacteria help to convert atmospheric nitrogen into usable forms such as nitrates and nitrites.These nitrogen fixing bacteria are commonly found in the roots of plants of pulses(legumes). These usable forms of nitrogen are absorbed by plants to produce amino acids, which in turn form proteins. When an animal eats these plants, nitrogen enters its body through the proteins present in plants.When plants and animals die, they start decomposing after some time. During this process, proteins containing nitrogen are converted into nitrates and nitrites by the action of decomposing bacteria ,which is present in the soil. Few other types of bacteria convert nitrates and nitrites into nitrogen gas.This way nitrogen cycle continues.

When first learning about the nitrogen cycle it can be pretty confusing! Hopefully, this movie is easy to understand and can make fish keeping for beginners easier! Once you know this cycle, it's pretty easy to cycle it. Just introduce a form of ammonia (fish food, a frozen shrimp overnight, a few hardy fish, or PURE ammonia for example) and the rest is testing for ammonia, nitrite and nitrate levels. Once most chemicals are cleared you can (slowly) add your fish to the aquarium!! If you have any questions, comment below of send a message! Music: Blue Eyes by Mika

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is continually cycled through the air, soil and living things. Plants take up nitrogen compounds as nitrates from the soil. Animals then eat these plants, thus getting their nitrogen. The process of nitrogen in the atmosphere being turned into nitrogen in the soils is called fixing. There are different ways that nitrogen is 'fixed; including nitrogen fixing bacteria in the soil which turns nitrogen from the air into nitrates. Decomposers in the soils break down animal excretion and dead organisms, returning nitrogen back to the soil as ammonia. Lightning can cause chemical reactions in the atmosphere, resulting in nitrogen reacting with oxygen to produce nitrous oxide. Burning fossil fuels also adds nitrous oxide to the atmosphere, resulting in nitric acid, but this is of course not a natural way of nitrogen fixing. Blue-green algae in the ocean also can fix nitrogen. This then provides sources of nitrogen to aquatic animals, and the nitrogen goes around a similar cycle to what happens on land. The Haber Process makes up approximately 30% of nitrogen fixing. Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air. This reduces the fertility of the soil.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among the atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems. The nitrogen cycle is of particular interest to ecologists because nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition. Human activities such as fossil fuel combustion, use of artificial nitrogen fertilizers, and release of nitrogen in wastewater have dramatically altered the global nitrogen cycle.

We suggest that you show learners a diagram of the nitrogen cycle at the beginning of this lesson. You can copy the diagram used in the video that has been included in this set of notes. In this lesson we start by exploring the properties of nitrogen. We show liquid nitrogen boiling at room temperature and how this very cold liquid can instantly freeze a flower. Nitrogen gas is quite inert and cannot be absorbed directly by most living things. Special chemical reactions are required to change nitrogen into soluble products. This process is called nitrogen fixation. In this lesson we show how nitrogen is fixed by lightning, bacteria and during industrial processes. We illustrate each of these methods. One of the highlights of this lesson is the reaction of nitrogen monoxide (colourless gas) and oxygen (colourless gas) to form nitrogen dioxide (brown gas). We have done this demonstration in plastic syringes linked together by tubing. This technique, which is inexpensive and easy to use, was developed by Bruce Mattson, Center for Microscale Gas Chemistry, Creighton University, Nebraska, USA. See his website for detailed information on using this technique in many different experiments:

We want to maximize the conversion of ammonia to nitrate in order to detoxify the environment for all living organisms in our aquarium. The Nitrogen cycle starts with the oxidation of ammonia to nitrite by nitrifying bacteria bacteria in the genus nitrosomonas. Nitrite is then quickly converted into nitrate by bacteria in the genus nitrobacter. This fully oxidized end product can be used by plants and algae for nitrogen assimilation or used as a substrate in a process called denitrification which reduces nitrate into nitrogen gas which then leaves the aquarium. The nitrogen cycle can be enhanced by supplying an ample amount of oxygen to the aquarium and or the filter directly.
