In Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. A cycle is a series of cha…
What are the essential features of a biogeochemical cycle?
What are the essential features of a biogeochemical cycle? The cycling or circulation of essential elements of life from the environment to the organisms and back to organisms in a characteristic path in the biosphere is called the Biogeochemical cycle. Several inorganic salts are essential for life (protoplasm).

- Natural events or human activities can disturb Biogeochemical cycles.
- Human activities include: Overuse of fertilizers or herbicides. - runoff affects bodies of water causing algae blooms.
- Natural events include: Volcanic activity.
How do humans interfere with biogeochemical cycles?
The large numbers of land animals raised to feed the Earth’s growing population results in increased carbon dioxide levels in the atmosphere due to farming practices, respiration, and methane production. This is another example of how human activity indirectly affects biogeochemical cycles in a significant way.
Why is the cell cycle considered to be important?
The cell cycle is the replication and reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in different ways, but overall it allows them to survive. Plants require the cell cycle to grow and provide life for every other organism on earth.
Why are biogeochemical cycles important to humans and our environment?
Biogeochemical cycles help in the regulation of natural elements that are necessary for living beings, by channeling through physical and biological phenomena.
How do biogeochemical cycle affect the environment?
Human activities have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
What is the most important biogeochemical process and why?
Explanation: One of the most important cycle in biochemical cycles is carbon cycle. Photosynthesis and respiration are important partners. While consumers emit carbon dioxide, producers (green plants and other producers) process this carbon dioxide to form oxygen.
What biogeochemical cycles are key to life?
Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
Why are biogeochemical cycles sustainable?
Biogeochemical cycles are considered sustainable because the matter and the energy in these cycles are continuously consumed, rearranged, stored, used, and renewed. In addition, they have these characteristics that remain relatively constant over a long period of time.
How does the environment affect life cycles?
In some species, transitions between the stages in their life cycles can be triggered by changes in environmental conditions. For example, many plant species require seasonal exposure to cold temperatures for seeds to germinate.
How does biogeochemical cycles affect deforestation?
Deforestation primarily affects biogeochemical cycling by disrupting the water cycle, allowing the environment to lose water more easily and significant elements and nutrients with it. The greatest impact of deforestation on a given area's biogeochemical processes occurs by interruption of the water cycle.

Why is biogeochemical cycle important?
Importance of Biogeochemical Cycle. Biogeochemical cycles help in the regulation of natural elements that are necessary for living beings, by channelling through physical and biological phenomenon. It acts as a recycling procedure in nature.
What are the elements in the biogeochemical cycle?
Types of Biogeochemical Cycles. Reservoir in sedimentary bio-geo cycle is Earth’s crust and include earth-bound elements such as phosphorus, calcium, iron and sulphur among others. Reservoir in gaseous bio-geo cycle is air or ocean and include carbon, oxygen and nitrogen.
What is the natural pathway through which essential elements in living matter undergoes circulation?
The natural pathway through which essential elements in living matters undergoes circulation is known as a biogeochemical cycle . The natural elements in the biogeochemical cycles flow from abiotic (non-living) components to biotic (living) components. Biogeochemical, as a term, refers to three aspects in each cycle.
Which cycle does phosphorus pass through?
Phosphorus cycle. Phosphorus mainly passes through hydrosphere, lithosphere and biosphere. It is essential for both animal and plant growth. However, it gradually depletes in soil. In comparison to the carbon cycle, the phosphorus cycle does not pass through the atmosphere.
What is the role of water cycle?
Water cycle also plays a critical role in weather, pressure and temperature in environment. Carbon cycle. Carbon moves from atmosphere to living organisms and back again to the atmosphere. Plants are taken as the starting point of carbon cycle. The main stages in carbon cycle are – photosynthesis, respiration, combustion and decomposition.
Why is water important to life?
Water is indispensable for life’s existence, and ocean plays a vital role in the cycle. Atmospheric water vapour causes precipitation for which evaporation from water surface is critical. Water cycle also plays a critical role in weather, pressure and temperature in environment.
Why are biogeochemical cycles important?
First, living things require many chemical elements, and these must be available at the right time, in the right amounts, and in the right concentrations relative to each other. This is the essence of, and the importance of, biogeochemical cycles.
What is Biogeochemical Cycle?
The biogeochemical cycle may be defined as the more or less circular path which brings about the circulation of chemicals and elements, including all essential elements from the environment to the organisms and back to the environment.
What are the processes that sustain life on Earth?
Second, sustained life on Earth is a function of ecosystems, and a primary ecosystem process is the cycling of chemicals necessary for life. On a larger scale, chemicals, nutrients, and trace elements necessary for life are made available from Earth through various parts of biogeochemical cycles. For example, soil and rock release nutrients to plants through weathering and biochemical processes; water infiltrates rock and soil to emerge as springs and streams necessary for life. In the ocean, single-cell algae release a sulfide compound that oxidizes in the atmosphere, producing condensation nuclei that are necessary to form clouds that transport water and sulfur to the land.
What is the effect of burning fossil fuels?
Burning of fossil fuels by industries and thermal power plants add sulfur dioxide ( SO₂) in the atmosphere. With rainwater, it forms sulfurous acid ( H2SO3) which on entering the living systems, interferes with the metabolic activities of the organisms.
Why is phosphorus important?
Phosphorus is an important and necessary constituent of protoplast as it is an essential constituent of nucleic acids, phospholipids, and many phosphorylated compounds. The phosphorus tends to circulate as the organic compounds on being broken down produce phosphates which are again available to plants.

Why are biogeochemical cycles important in the environment Brainly?
Biogeochemical cycles are important because they regulate the elements necessary for life on Earth by cycling them through the biological and physical aspects of the world. Biogeochemical cycles are a form of natural recycling that allows the continuous survival of ecosystems.
Why are natural cycles important in the environment?
Plants absorb the carbon dioxide from the atmosphere, which is used by them to live. Together with water they get from the soil they make substances that are needed for growth.
