The nitrogen cycle is a complex process that involves the transformation of nitrogen from one form to another. Nitrogen gas (N2) makes up about 78% of the Earth’s atmosphere, but it is not readily usable by most organisms. Therefore, it must undergo a series of transformations to become accessible to plants and animals.
Processes in the Nitrogen Cycle
Nitrogen Fixation: The first step in the nitrogen cycle is nitrogen fixation, where atmospheric nitrogen is converted into a usable form. This process can be carried out by certain bacteria, either free-living or in symbiotic relationships with plants. These bacteria convert nitrogen gas into ammonia (NH3) or ammonium (NH4+), which can be utilized by plants.
Nitrification: After nitrogen fixation, the next step is nitrification. This process involves the conversion of ammonium into nitrite (NO2-) and then into nitrate (NO3-). Nitrifying bacteria carry out these transformations, making nitrogen available for plant uptake.
Assimilation: Plants take up nitrate ions from the soil and incorporate them into their tissues. Animals obtain nitrogen by consuming plants or other animals. Nitrogen is then used to synthesize proteins and DNA, essential for growth and development.
Ammonification: When plants and animals die or produce waste, the organic nitrogen in their tissues is broken down by decomposers. This process, known as ammonification, converts organic nitrogen compounds into ammonium, which can be further utilized in the nitrogen cycle.
Denitrification: Denitrification is the final step in the nitrogen cycle. It is carried out by denitrifying bacteria, which convert nitrate back into nitrogen gas. This process returns nitrogen to the atmosphere, completing the cycle.
Human Impact on the Nitrogen Cycle
Human activities have significantly disrupted the nitrogen cycle, leading to environmental issues. One of the main contributors is excessive fertilizer use in agriculture.

Overview of the Phosphorus Cycle
The phosphorus cycle begins with the weathering of rocks, which releases phosphate ions into the soil. Plants then absorb these phosphate ions through their roots, incorporating them into their tissues. When animals consume plants, they acquire phosphorus, which becomes a part of their bodies.
When plants and animals die, their organic matter decomposes, releasing phosphorus back into the soil. This process is known as mineralization. Phosphorus can also be released from the soil into water bodies through erosion and runoff.
Movement of Phosphorus through Reservoirs
Phosphorus moves between different reservoirs in the environment, primarily soil, water, and organisms. In the soil, phosphorus is present in both organic and inorganic forms. Plants take up inorganic phosphate ions from the soil, utilizing them for growth and development. When animals consume plants, they assimilate phosphorus into their bodies.
Phosphorus can also enter water bodies through various pathways. Runoff from agricultural fields, where phosphorus-rich fertilizers are often used, can carry excess phosphorus into rivers, lakes, and oceans. Additionally, erosion of phosphorus-rich soil can contribute to the phosphorus load in water bodies.
Consequences of Human Activities on the Phosphorus Cycle
Human activities have significantly disrupted the phosphorus cycle, leading to water pollution and ecological imbalances. One major contributor to this disruption is mining. Phosphorus is extracted from rocks and used in the production of fertilizers, which are then applied to agricultural fields. However, excessive use of fertilizers can result in the accumulation of phosphorus in the soil, leading to runoff and water pollution.
Agricultural runoff is another significant source of phosphorus in water bodies. When fertilizers are applied to fields, rainwater can wash away the excess phosphorus, carrying it into rivers and lakes. This excessive phosphorus in water bodies can cause eutrophication, a process where excessive nutrients lead to the overgrowth of algae. The subsequent depletion of oxygen in the water can harm aquatic life.
Preserving the Phosphorus Cycle and Water Quality
