Biogeochemical Cycles and Human ActivitiesAmos Watentena
A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. In geography and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. The following presentation discusses the role of humans in the biogeochemical cycles.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. BIOGEOCHEMICAL CYCLES
Biogeochemical Cycles, or Nutrient cycles, is
how elements, chemical compounds, and other
forms of matter are passed from one organism to
another and from one part of the biosphere to
another.
Types of Biogeochemical Cycles:
Hydrologic- ex water cycle
Atmospheric- ex carbon cycle and nitrogen cycle
Sedimentary – ex phosphorus cycle
4. Biogeochemical Cycle
Biogeochemical cycle 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 change which comes back to the starting point and
which can be repeated.
The term "biogeochemical" tells us that biological, geological and chemical
factors are all involved. The circulation of chemical nutrients like carbon,
oxygen, nitrogen, phosphorus, calcium, and water etc. through the biological
and physical world are known as biogeochemical cycles.
In effect, the element is recycled, although in some cycles there may be
places (called reservoirs) where the element is accumulated or held for a
long period of time (such as an ocean or lake for water).
5. ‘Fundamentals’ of biogeochemical cycles
All matter cycles...it is neither created nor
destroyed...
As the Earth is essentially a closed system with
respect to matter, we can say that all matter on
Earth cycles .
Biogeochemical cycles: the movement (or cycling)
of matter through a system
6. by matter we mean: elements (carbon, nitrogen, oxygen) or
molecules (water)
so the movement of matter (for example carbon) between
these parts of the system is, practically speaking, a
biogeochemical cycle
The Cycling Elements:
macronutrients : required in relatively large amounts
"big six":
carbon , hydrogen , oxygen , nitrogen , phosphorous
sulfur

PRECIPITATION - water vapor
(gas) changing into a liquid or solid
such as rain, hail, sleet or snow
TRANSPIRATION - water loss from
plants when water vapor goes out through
stomates (little openings) in leaves
RUN-OFF - CONDENSATION - water vapor (gas)
changing to a tiny drops of water (liquid) that form
clouds or rain
water moving across the Earth’s surface (stream, river,
gully)
ACCUMULATION - water gathering into an
area (pond, lake, stream or ocean)
12. Water Cycle
Water cycle is the cycle of evaporation and
condensation that controls the distribution of the
earth's water as it evaporates from bodies of water,
condenses, precipitates, and returns to those bodies of
water.
13. Water Cycle
Water can be in the atmosphere, on the land, in the
ocean, and even underground. It is recycled over and
over through the water cycle. In the cycle, water
changes state between liquid, solid (ice), and gas
(water vapor).
Most water vapor gets into the atmosphere by a
process called evaporation. This process turns the
water that is at the top of the ocean, rivers, and lakes
into water vapor in the atmosphere using energy from
the Sun. Water vapor can also form from snow and ice
through the process of sublimation and can evaporate
from plants by a process called transpiration.

(salt water intrusion and groundwater depletion)
2Clear vegetation from land for agriculture, mining, road
and building construction. (nonpoint source runoff

3Degrade water quality by adding nutrients(NO2, NO3,
PO4) and destroying wetlands (natural filters).
4Degrade water clarity by clearing vegetation and
increasing soil erosion.
17. CARBON CYCLE
Use the next diagram to help you
define the relationship of the
following terms to the carbon cycle.
respiration
photosynthesis
decomposition
combustion
erosion
18. Carbon cycle:-
Carbon is another nutrient that all organisms need. In
fact, it is the basic building block of all living
things. Like water, carbon moves through an
ecosystem in a cycle. Here is how the cycle works.
Carbon is present in the atmosphere as carbon
dioxide. Water also contains carbon dioxide as it
can dissolve it. Producers (plants and algae) use it to
perform photosynthesis and make food. Now the
carbon is in the producers. Herbivores eat the plants
and carnivores eat the herbivores. Now the
carbon is in animals. Both plants and animals respire.
Their respiration returns carbon dioxide to the
19. Plants in water need carbon dioxide to perform photosynthesis and release
oxygen. Fish use the
oxygen to breathe and the plants for food. Thus, fish depend on the carbon
dioxide cycle.

22. NITROGEN CYCLE
Simplified
Use the diagram to help you define the
relationship of the following terms to the
nitrogen cycle.

denitrification
23. Nitrogen Cycle
Nitrogen cycle the continuous sequence of natural
processes by which nitrogen in the atmosphere
and nitrogenous compounds in the soil are
converted, as by nitrification and nitrogen fixation,
into substances that can be utilized by green
plants and then returned to the air and soil as a
result of denitrification and plant decay.
24. Nitrogen Cycle
Nitrogen fixation:
The conversion of atmospheric nitrogen into
nitrogenous compounds by bacteria (Rhizobia) found
in the root nodules of legumes and certain other
plants, and in the soil.
Assimilation:
Plants take nitrogen from the soil, by absorption
through their roots in the form of their nitrate ions or
ammonium ions. All nitrogen obtained by animals can
be traced back to the eating of plants.
25. Nitrogen Cycle
Nitrogen fixation:
The conversion of atmospheric nitrogen into
nitrogenous compounds by bacteria (Rhizobia) found
in the root nodules of legumes and certain other
plants, and in the soil.
Assimilation:
Plants take nitrogen from the soil, by absorption
through their roots in the form of their nitrate ions or
ammonium ions. All nitrogen obtained by animals can
be traced back to the eating of plants.
27. Mineralization or Ammonification
Decomposers: earthworms, termites, slugs,
snails, bacteria, and fungi
Uses extracellular enzymes initiate
degradation of plant polymers
Microorganisms uses:
Proteases, lysozymes, nucleases to degrade
nitrogen containing molecules
28. • Plants die or bacterial cells lyse release of
organic nitrogen
• Organic nitrogen is converted to inorganic
nitrogen (NH3)
• When pH<7.5, converted rapidly to NH4
• Example:
Urea NH3 + 2 CO2
29. Immobilization
The opposite of mineralization
Happens when nitrogen is limiting in the
environment
Nitrogen limitation is governed by C/N ratio
C/N typical for soil microbial biomass is 20
C/N < 20 Mineralization
C/N < 20 Immobilization

32. Phosphorus Cycle
The phosphorus cycle is the process in which phosphorus
travels from its main source of rocks through ecosystems
to living organisms.
Phosphate Mining
Phosphate rock is found from 15-50ft below the ground in a
phosphate matrix. The matrix is comprised of phosphate
pebbles, sand, and clay. The sandy layer is removed by
electrically operated drag lines. Then high pressure water
guns turn the sandy layer into a mixture called slurry. The
slurry is then sent to a processing facility. After the
phosphate is collected it is use for common human
products, such as fertilizer.
33. Phosphorus Cycle
Excretion
Animals are a key element in the phosphorous
cycle. They consume plants containing
phosphorous and then excrete. The excrement is
then turned into run-off in water and decomposed
in either the ground or nearby water bodies by
decomposers.
Decomposition
Organic material breaks down, returning organic
phosphorus to the soil as inorganic phosphorus.
The inorganic phosphorus then enters the oceans
through runoff and erosion of rocks containing
phosphorus.
34. IMPORTANCE OF PHOSPHOROUS
CYCLE
• 1.Phosphorous is an essential nutrient of both plants
and animals.
• 2. It is part of DNA molecules which carry genetic
information.
• 3. It is part of ATP and ADP) that store chemical
energy for use by organisms in cellular respiration.
• 4. Forms phospholipids in cell membranes of plants
and animal cells.
• 5. Forms bones, teeth, and shells of animals as
calcium phosphate compounds.
36. Sulfur Cycle
Sulfur cycle is the natural cycle which includes
the mineralization of organic sulfur to sulfide,
oxidation of this to sulfate, and reduction of this to
sulfide followed by microbial incorporation of this
into organic compounds.
37. Sulfur Cycle
The sulfur cycle includes both gases and solids.
Hydrogen sulfide gas (H2S) is released into the
atmosphere by volcanic eruptions, hot springs ,
and the anaerobic decay of sulfur-containing
biological material in swamps, bogs, and tidal flats.
Certain marine algae produce dimethyl sulfide,
(CH3)2S, a volatile compound that enters the
atmosphere as tiny droplets.
The burning of fossil fuels, such as coal and oil
releases sulfur dioxide into the atmosphere.
38.
39. HUMAN IMPACTS TO SULFUR
CYCLE
Approximately 1/3 of all sulfur emitted into
atmosphere comes from human activities.
1. Burning sulfur containing coal and oil to
produce electric power (SOx = acid deposition).
2. Refining petroleum – (SOx emissions)
3. Smelting to convert sulfur compounds of
metallic minerals into free metals (Cu, Pb, Zn)
4. Industrial processing.
40. 1Sulfur is a component of most proteins and some vitamins.
2Sulfate ions (SO4 2- ) dissolved in water are common in
plant tissue. They are part of sulfur-containing amino acids
that are the building blocks for proteins.
3Sulfur bonds give the three dimensional structure of amino
acids.
4Many animals, including humans, depend on plants for
sulfur-containing amino acids.
