Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.
Types of Biogeochemical Cycles. Biogeochemical cycles are basically divided into two types: Gaseous cycles – Includes Carbon, Oxygen, Nitrogen, and the Water cycle. Sedimentary cycles – Includes Sulphur, Phosphorus, Rock cycle, etc. Let us have a look at each of these biogeochemical cycles in brief: Water Cycle
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
Jan 15, 2021 · The nitrogen cycle refers to the cycle of nitrogen atoms through the living and non-living systems of Earth. The nitrogen cycle is vital for life on Earth. Through the cycle, atmospheric nitrogen is converted to a form which plants can incorporate into new proteins.
Key Points. Bacteria, such as cyanobacteria, convert nitrogen into nitrogen gas via nitrogen fixation. Nitrogen fixation occurs in three steps: ammonification, nitrification, and denitrification. Human activity can release nitrogen into the environment by the combustion of fossil fuels and by the use of artificial fertilizers in agriculture.
Feb 25, 2020 · The series of processes by which nitrogen and its different forms are circulated and interconverted in nature with the help of living organisms is called the nitrogen cycle. It shows the path that nitrogen follows through the biogeochemical cycle using its storage reservoirs, such as the atmosphere, living organisms, and soil.
Aug 5, 2023 · The nitrogen cycle is a biogeochemical cycle that converts nitrogen into various forms throughout the ecosystem. Nitrogen is an essential element for life that organisms use in the synthesis of amino acids, proteins, and nucleic acids.
Jul 27, 2024 · The biogeochemical cycles of four elements—carbon, nitrogen, phosphorus, and sulfur—are discussed below. The cycling of these elements is interconnected with the water cycle . For example, the movement of water is critical for the leaching of sulfur and phosphorus into rivers, lakes, and oceans.
This article explores how nitrogen becomes available to organisms and what changes in nitrogen levels as a result of human activity means to local and global ecosystems.
Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur; Explain how human activities have impacted these cycles and the potential consequences for Earth
