State the different types of bio-geochemical cycles and explain the importance of those cycles.
Answers
the different types of biogeochemical cycles are nitrogen cycle, carbon cycle, oxygen cycle, water cycle. it is to ensure sustainable of life
Nutrients are chemical compounds.
These are natural path which are present in the living thing is constantly circulating.
Nutrients from an ecosystem are never lost.
These nutrients are recycled at all stages.
This nutrient recycle with the help of many components present in an ecosystem and it is called as the cycle of nutrients or the biogeochemical cycle.
Types of Biogeochemical cycles
These cycles can generally divided into two kinds such as the biogeochemical gaseous cycle and the biogeochemical sedimentary cycle. The classification is mainly based on the reservoir.
Each reservoir in a nutrient cycle consists of an abiotic part and an exchange pool where the biotic and abiotic aspects are rapidly exchanged.
Gaseous cycles:
Gaseous cycles exist through evaporation in the atmosphere or in oceans. The various cycles of gases are the cycle of nitrogen, carbon, oxygen, and the water.
Sedimentary cycles:
The sedimentary cycles have the crust of the earth as a reservoir. These cycles include the more earth-bound chemical components, such as iron, calcium, sulphur, etc.
The gaseous cycles move faster than the sedimentary cycles.
A large atmospheric reservoir could be one of the main reasons for this cycle.
Carbon cycle:
Every matter is referred to an organic when it contains carbon.
Carbon is essential for the production of nutrient molecules like carbohydrates, proteins, and fats. Plants use carbondioxide and prepare food.
Animals consume plants, in turn.
When plants and animals break down, carbon dioxide is released.
During the breathing process, animals release carbon dioxide.
When an organic matter is burnt, carbon is released and mixes in the atmosphere to form of Carbon dioxide.
This carbon dioxide is again used by plants and the cycle of biogeochemistry continues.
Water cycle:
Water is absorbed by plants from the soil.
The water is released from the perspiration in plants. In animals, water is present in atmost all the parts of the body and they also drink water.
Water is also released due to perspiration and evaporation in the atmosphere.
The water is transferred from one body of a organism to another when animals are eaten by other animals.
When animals and plants break down, water is released because of chemical processes.
This means that water is continually recycled through the various ecosystem components.
Nitrogen cycle:
Nitrogen is a most important essential element in the genetical materials like ""DNA"" and ""RNA"".
The nitrogen cycle is regarded as the most complex of all biogeochemical cycles and is found in many forms in nature.
Nitrification, denitrification, fixation of nitrogen, etc.
These are all processes linked to the nitrogen cycle.
In conclusion, all these various biogeochemical cycles are not isolated.
The most important link is water movement through the cycles of water.
For the release of ""phosphate"" and ""nitrogen"" into the various water bodies for water movement is most important, including the oceans.
