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.

Sulfur is a chemical element with symbol S and atomic number 16 with atomic mass 32.065.
It is abundant, multivalent, brittle, yellow, tasteless, odourless and non-metallic element.
Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth.
In the Bible, sulfur is called brimstone .
Today, almost all elemental sulfur is produced as a by product of removing sulfur-containing contaminants from natural gas and petroleum.
Most soil sources of S are in the organic matter and therefore concentrated in the top soil or low layer.
Under normal conditions, sulfur atom forms cyclic octatomic molecules with a chemical formula S8.
Sulphur is the most abundent and widely distributed element in the nature and found both in free as well as combined states.

What is The Meaning Of Biodegradation?
A biodegradable product can dissolve easily in the environment without destroying nature. It’s the opposite of plastic and Styrofoam, which harm the environment.
The meaning of biodegradation is breaking down of organic substances by the help of other living organisms such as bacteria and microbes.
History:
The first known use of the word in biological text was in 1961 when employed to describe the breakdown of material into the base components of carbon, hydrogen, and oxygen by microorganisms .

2. What is sulfur? Sulfur is the 10th most abundant element in the environment, with atomic number 16. It is a bright yellow crystalline solid in its normal state, with most of it stored underground in rocks and minerals and in ocean floor deposits. Sulfur is used for fertilizers, gunpowder, matches, and in insecticides and fungicides. It is a part of vitamins, proteins and hormones that are considered critical to climate and health of various ecosystems.
4. Steps of Sulfur Cycle The cycle begins with the weathering of rocks, which releases stored sulfur. Sulfur comes into contact with the air, converting it to sulfate (SO4). Sulfate is taken up by plants and microorganisms and is changed to organic form. Sulfur moves up the food chain. When organisms die, some of the sulfur is released back to sulfate and enter microorganisms.
5. Steps of Sulfur Cycle Natural sources emit sulfur into the air. Sulfur eventually settles back to the Earth or comes through rainfall, with some also going to the ocean. Sulfur is also drained to rivers and lakes, eventually to the oceans. Some of the sulfur from oceans go back to the atmosphere through the sea spray. Remaining sulfur go to ocean floor and form ferrous sulfide, which is responsible for the black color of most marine sediments.
6. Effects of Sulfur Cycle on Nature Sulfur is one of the processes that allow natural weathering and other natural processes. Sulfur Cycle does not allow acid rains because it regulates the amount of sulfur present in the atmosphere, hydrosphere, and lithosphere. Sulfuric acid forms sulfuric acid smog when it mixes with water vapor.
7. Effects of Human Progress on the Sulfur Cycle Human activities since the start of the Industrial Revolution contributed to most of the sulfur that enters the atmosphere. One-third of all sulfur that reaches the atmosphere comes from human activities. Emissions from human activities react to produce sulfate salts that create acid rain. Sulfur dioxide aerosols absorb ultraviolet rays, which cools areas and offsets global warming caused by greenhouse effect.
