The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into various chemical forms as it circulates among the atmosphere and 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 pool 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.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Toxoplasma gondii is an intracellular zoonotic protozoan parasite, infect both humans and animals population worldwide. It can also cause abortion and inborn disease in humans and livestock population. In the present study total of 313 domestic animals were screened for Toxoplasma gondii infection. Of which 45 cows, 55 buffalos, 68 goats, 60 sheep and 85 shaver chicken were tested. Among these 40 (88.88%) cows were negative and 05 (11.12%) were positive. Similarly 55 (92.72%) buffalos were negative and 04 (07.28%) were positive. In goats 68 (98.52%) were negative and 01 (01.48%) was recorded positive. In sheep and shaver chicken the infection were not recorded.

Nitrogen Cycle
3. What is Nitrogen Cycle ?
The series of processes by which nitrogen and its
compounds are interconverted in the environment.
The nitrogen cycle is the process by which nitrogen
is converted between its various chemical forms.
This transformation can be carried out through both
biological and physical processes.
Nitrogen Cycle
4. Forms of Nitrogen
1. organic nitrogen as-
ammonium (NH4+),
nitrite (NO2-),
nitrate (NO3-),
nitrous oxide (N2O),
nitric oxide (NO)
2. inorganic nitrogen as nitrogen gas (N2).
Nitrogen Cycle
5. Steps of Nitrogen Cycle
Nitrogen cycle consists of the following steps-
1. Nitrogen Fixation
2. Nitrogen assimilation
3. Ammonification
4. Nitrification
5. Denitrification and
6. Sedimentation
Nitrogen Cycle
6. Elaboration of different steps
1. Nitrogen Fixation
The conversion of free nitrogen of atmosphere into the biologically
acceptable form or nitrogenous compounds.
N2 + 8 H+ + 8 e− → 2 NH3 + H2
There are following ways to convert N2 into more chemically reactive
forms:
a) Biological Nitrogen fixation
b) Physicochemical nitrogen fixation
c) Industrial nitrogen fixation
Nitrogen Cycle
7. a) Biological Nitrogen fixation
some symbiotic bacteria , blue-
green algae and some free-living
bacteria are able to fix nitrogen as
organic nitrogen.
Example:
symbiotic bacteria: Rhizobium
b) Physicochemical nitrogen fixation
In this process, atmospheric nitrogen
combines with oxygen (as ozone) during
lightning or electrical discharges in the
clouds and produces different nitrogen
oxides:
N2 + 2(O) = 2NO
2NO + 2(O) = 2NO2
2NO2 + O = N2O5
c) Industrial nitrogen fixation
Under great pressure, at a temperature of 600 C and with the use
of an iron catalyst, hydrogen and atmospheric nitrogen can be
combined to form ammonia (NH3) in the Haber-Bosch process.
Nitrogen Cycle
8. 2. Nitrogen assimilation :
In this process , Inorganic nitrogen in the form of
nitrates , nitrites , and ammonia is absorbed by the
green plants via their roots and then it is converted into
nitrogenous organic compounds.
Nitrogen Cycle
9. 3. Ammonification
It is the process of releasing ammonia by certain microorganisms
utilizing organic compounds derived from the dead organic
remains of plants and animals and excreta of animals.
The microorganisms especially involved are actinomycetes and
bacilli.
( Bacillus ramosus , B. vulgaris, B. mesenterilus )
Nitrogen Cycle
10. 4. Nitrification
Nitrification is a process of biological oxidation of ammonia to
nitrate by certain microorganisms in soil and ocean.
• Nitrosomonas ammonia to nitrites (NO2-)
• Nitrobacter oxidation of the nitrites into nitrates (NO3-).
Nitrogen Cycle
11. 5. Denitrification
Denitrification is the reduction of nitrates back into the largely
inert nitrogen gas (N2).
Some denitrifying bacteria are-
• Thiobacillus denitrificants
• Micrococcus denitrificants
• Pseudomonas aeruginosa
2NO3- > 2NO2- > 2NO > N2O > N2
Nitrogen Cycle
12. 6. Sedimentation
Sometimes , nitrates of soil are locked up in the rocks while they
are washed down to the sea or leached deeply into the earth
along with percolating water.
This phenomena is known as sedimentation.
Nitrogen Cycle

14. Conclusion
Nitrogen is the most abundant element in our
planet’s atmosphere. Approximately 78% of the atmosphere is
made up of nitrogen gas (N2).
Nitrogen is a crucially important component for all life. It is an
important part of many cells and processes such as amino acids,
proteins and even our DNA. It is also needed to
make chlorophyll in plants, which is used in photosynthesis to
make their food.
