The carbon cycle describes the movement of carbon through Earth's atmosphere, oceans, soil, and living things. Carbon is absorbed by plants through photosynthesis and enters the biosphere, and is released back into the atmosphere through respiration and decomposition. Burning fossil fuels has increased the amount of carbon dioxide in the atmosphere, contributing to global climate change. The carbon cycle is essential for life and affects Earth's climate.

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 .
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
a ppt on the biology chapter natural resources that covers all the major points on the Carbon Cycle. For class 9 students. Hope you like it and it helps you!!
Carbon is an essential element for all life forms on Earth. Whether these life forms
take in carbon to help manufacture food or release carbon as part of respiration, the
intake and output of carbon is a component of all plant and animal life.
The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced,
meaning that the amount of carbon naturally released from reservoirs is equal to the
amount that is naturally absorbed by reservoirs. Maintaining this carbon balance
allows the planet to remain hospitable for life. Scientists believe that humans have
upset this balance by burning fossil fuels, which has added more carbon to
the atmosphere than usual and led to climate change and global warming.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. WHAT ISTHE CARBON CYCLE
• All life is based on the element carbon that has the symbol ‘C’ and the atomic number 6.
• Carbon is the major chemical constituent of most living matter including human-beings.
Yet by weight, carbon is not one of the most abundant elements on the Earth‘s crust.
• Carbon moves in complex chemical and physical transfers from sources, or reservoirs,
where carbon is released, to sinks, where carbon is taken up.
• This movement is the global carbon cycle.
3. WHAT ISTHE CARBON CYCLE
• Earth's atmosphere, ocean, land, and living things can be both sources and sinks
of carbon.
• The processes of photosynthesis, respiration, death, and decomposition move
carbon through the carbon cycle partly as carbon dioxide.
• In Earth's atmosphere, CO2 is only about 0.03% by volume, but it is an important
"greenhouse" gas. It traps in the lower atmosphere much of the heat radiated
from the Earth's surface.
4. WHAT ISTHE CARBON CYCLE
The carbon cycle is therefore the circulation of carbon atoms in the biosphere as a
result of photosynthetic conversion of carbon dioxide into complex organic
compounds by plants which are consumed by other organisms: the carbon returns
to the atmosphere in the form of carbon dioxide as a result of respiration, decay by
fungi, bacteria and combustion of fossil fuels
5. SOURCES OF CARBON
• Carbon is stored on the planet in the following major reservoirs:
• (1) as organic compounds (e.g. sugar, starch) in living and dead organisms in the biosphere;
• (2) as the gas carbon dioxide (CO2 ) and methane (CH4 ) in the atmosphere;
• (3) as organic matter in soil;
• (4) in the lithosphere as fossil fuel and sedimentary rocks such as limestone (including chalk)
and dolomite;
• (5) in the oceans as dissolved hydrocarbons and as calcium carbonate in the shells of marine
creatures (e.g. coral).
6. HOW DOESTHE CARBON CYCLEWORK
• When it’s in the atmosphere, carbon is combined with two oxygen atoms making a
molecule called carbon dioxide (CO2).
• Plants absorb carbon dioxide and sunlight to make their own food.This process is
called photosynthesis. In this process, carbon becomes part of the plant, and the
plant releases oxygen.
• When the plants die and are buried under layers of earth for millions of years, they
may become fossil fuels like coal, oil and natural gas.
7. HOW DOESTHE CARBON CYCLEWORK
• When these fuels are burned, the carbon is released back to the atmosphere.
• Some of it is as carbon monoxide (where carbon is combined with only one oxygen
atom), and this is a poisonous gas.
• The rest combines with two oxygen atoms to again form CO2. Animals do just the
opposite as plants.They inhale air from the atmosphere, use the oxygen, and
exhale CO2.
9. WHY ISTHE CARBON CYCLE
IMPORTANT
• The carbon cycle is essentially nature's way of reusing carbon atoms in different
ways and in varying places.
• The carbon cycle is vitally important to life on earth
• Through photosynthesis and respiration, it is the way the earth produces food and
other renewal resources
10. WHY ISTHE CARBON CYCLE
IMPORTANT
• Through decomposition it serves as the earth’s waste disposal system
• Carbon containing gases in the atmosphere affect the earth’s climate. Increased carbon dioxide in the
atmosphere has been responsible for half of the climate warming observed in recent decades
• Carbon dioxide (CO2) plays a key role in trapping heat in the atmosphere—one of the basic mechanisms
behind the greenhouse effect, which raises temperatures near the earth’s surface.
• Another factor that makes the cycling of carbon important is that carbon plays a central role in
combustion—burning—and in the last 200 years we have dramatically changed the carbon cycle through
burning fossil fuels, which has released large volumes of CO2 into the atmosphere.
11. HUMAN EFFECTS ONTHE CARBON
CYCLE
• The carbon cycle has major effects on global climate
• The burning of fossil fuels at the presently alarming rate increases global
warming. This is due to the increasing amount of greenhouse gases, specifically
CO2, which capture heat easily thus increasing global temperature.
• At present, there is a fear of the greenhouse effect increasing global warming to
an almost dangerous high. The excess carbon dioxide from the burning of fossil
fuels is responsible for the gradual yet constant rise in temperature over the past
few decades.
12. HUMAN EFFECTS ONTHE CARBON
CYCLE
• Also, substantial areas of forest have been cut down, removing a pathway for
CO2 absorption. Consequently, recent times have seen the amount of CO2 in the air
increase and the amount of oxygen decrease.
• Because there is so much oxygen in the air, the oxygen drop is hardly noticeable, but as
there is very little CO2 (0.038% of the atmosphere) the extra CO2 from burning and
deforestation has caused a dramatic rise.
• This has contributed to an enhanced greenhouse effect in recent decades.
• Given the potentially serious consequences for the earth’s climate of this enhanced
greenhouse effect, great importance is now placed on ways of reducing CO2emissions and
on reducing the CO2 already in the air.
