Carbon is essential for life and is continuously cycled through Earth's biosphere, lithosphere, hydrosphere and atmosphere. The carbon cycle involves the exchange of carbon reservoirs between the atmosphere, ocean, biomass and fossil fuels. Photosynthesis absorbs carbon from the atmosphere which enters the biosphere, and respiration and decomposition release it back into the atmosphere. Human activity such as burning fossil fuels has increased carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle balance.

More advanced treatise of the carbon and nitrogen cycles. Could be useful for teachers who have limited science background or for students in upper middle or high school.
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.
The diagram explains about carbon cycle that exists on land. Carbon Cycle is a biogeochemical cycle where various carbon compounds are interchanged among the various layers of the earth, namely, the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere. There are 4 main steps in this carbon cycle.

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”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

CARBON CYVLE - Ankita 8
9. What is the ‘Carbon Cycle’ ?
The carbon cycle is a series of events that involves the cyclic movement and transformation
of carbon between living organisms and the environment. Essentially, this is a natural way of
reusing carbon molecules in different geographic locations.
Basically, three major carbon-bearing reservoirs exist in the planet: the lithosphere(land),
the hydrosphere(water), and the atmosphere(air).
All of which are acted upon out by the biosphere (living organisms). Living organisms, in
general, play an important role in maintaining the balance between the other reservoirs.
By determining the interaction between these reservoirs and tracing the route through which
carbon are transported from the source to the sink, the interconnected carbon cycles on
Earth are described precisely.
CARBON CYVLE - Ankita 9
11. Carbon Cycle Steps
How It Is Used Biologically
• All biological and geological processes are important in
maintaining the carbon balance in the planet. The carbon cycle is
divided into the following steps
CARBON CYVLE - Ankita 11
13. 1. Entry of Carbon into the Atmosphere
The entry of carbon (in the form of
carbon dioxide) in the atmosphere
marks the start of the carbon cycle.
Before this, carbon dioxide goes
through the process of respiration
(process by which organisms
release energy from their food) and
combustion (process of burning).
Such both processes involve the
releasing carbon dioxide into the
atmosphere.
CARBON CYVLE - Ankita 13
14. 2 Carbon Dioxide Absorption By Producers
The next step is the entry of the
carbon dioxide in the
photosynthetic process.
Photosynthetic organisms
like plantsand algae(called as
producers) transform carbon
dioxide into sugars for energy use
and for their own reproduction.
CARBON CYVLE - Ankita 14
15. 3 Passing of the Carbon Compounds in the Food Chain
Following the above step is the entry
of the carbon compounds from the
plants (producers) themselves to the
food chain. When animals consume
(hence consume) these plants, the
carbon compounds are received by
them.
CARBON CYVLE - Ankita 15
16. 4 Return of the Carbon To the Atmosphere
. The next step is the return of the carbon to the atmosphere due to the decomposers
(bacteria and fungi) eating the dead bodies of animals. This is because the process
of decomposition gives off carbon dioxide as a by-product.

divided into the following major reservoirs of carbon interconnected
by pathways of exchange
on the land
in the sea
CARBON CYVLE - Ankita 17
18. This type of carbon cycling involves the
annual changes that occur within the
atmosphere, terrestrial ecosystems, and
the marine ecosystem.
This type of cycling is named as such
because the movement of carbon across
reservoirs only takes relatively short time
(minutes, hours, days, months, or years )
CARBON CYVLE - Ankita 18
19. This type of carbon cycling is the
slower form since it takes thousands
to millions of years to occur.
The excess carbons from the short
term cycling are stored into the “long
term” reservoir until they are
removed after a long time.
CARBON CYVLE - Ankita 19
20. The major source of carbon in the atmosphere comes
from carbon dioxide. Carbon dioxide enters the
atmosphere through respiration and combustion process.
The process of photosynthesis involves the absorption of
CO2 by plants to produce carbohydrates and the equation
is as follows.
Carbon compounds are passed along the food chain from
the producers to consumers. The majority of the carbon
exists in the body in the form of carbon dioxide
through respiration. The role of decomposers is to eat the
dead organism and return the carbon from their body
back into the atmosphere and the equation goes like
these:
CARBON CYVLE - Ankita 20
21. • Marine animals convert carbon
which is present in their diet to
produce calcium carbonate . They
use the carbonates to make their
shells. As time passes the dead
organisms get collected in the sea to
form limestone and the formed
limestone rocks formed gets
exposed to air. Due to this exposure,
they get weathered and hence the
carbon is released back into the
atmosphere as carbon dioxide.
CARBON CYVLE - Ankita 21
22. • Exchanges of carbon take place in several ways-
including respiration, transpiration, combustion, and decomposition. The carbon
balance, or carbon budget, is the balance of exchange between the four reservoirs.
• Debate about 're-balancing the carbon cycle' arises from a concern that use of fossil
fuels, which has accelerated since the start of the industrial revolution, has caused
carbon to accumulate in the atmosphere. Levels of CO2 in the atmosphere are
estimated to have risen from 280 ppm to almost 400 ppm since 1800 and this is
linked to global warming.
• It is therefore argued that the carbon cycle should be re-balanced by reducing the
amount of CO2 in the atmosphere.
CARBON CYVLE - Ankita 22
23. • Like any other natural cycles, the carbon cycle is essential for living
organisms and biological systems in general. Discussed below are some of
them:
1. Essential For Life
2. Important For the Maintenance of the Balance in Ecosystems
3. Critical To Food Chain
4. Important For Climate Regulation
CARBON CYVLE - Ankita 23
24. • As alluded to earlier, all living organisms are
made up of carbon or one way or another;
hence, the mere fact of it is very essential
for life itself. When the process fails, life
may begin to disrupt, and may even cause
the cessation of it.
CARBON CYVLE - Ankita 24
25. • The process of carbon cycle is very
important in the maintenance of
balance in ecosystems due to the
movement of carbon in various
reservoirs. If ever imbalance happens,
serious environmental disasters like
global warming may occur.
• At present, scientists and researchers
alike are still searching for novel
methods of using other non-carbon
sources for energy resource.
CARBON CYVLE - Ankita 25
26. • The close relationship between carbon
cycle and food chain boils down to the
fact that all living organisms are made
up of carbon.
• Through food chains (and food
webs), the carbon present in the
producers migrate to the consumers
that eat them. Consumers that eat
other consumers as well receive the
carbon from their food as well.
CARBON CYVLE - Ankita 26
27. Carbon dioxide and methane are the two
carbon-based gases that significantly
contribute to global warming. Since they are
made up of carbon, the process of carbon
cycle obviously determine the amount of
these gases in the atmosphere.
When there is a huge amount of carbon
released into the atmosphere, the level
of greenhouse gases increases, and therefore
trapping more heat in the Earth. Hence, the
understanding of how carbon cycle occurs in
the environment paves the way for the
development of the understanding for world
climate.
CARBON CYVLE - Ankita 27
28. Humans, in general, have already disturbed the natural process of carbon
cycle since the start of the industrial revolution. Look around you. It is
already becoming apparent how the atmospheric carbon dioxide
concentrations (as well as other greenhouse gases) are increasing as results of
domestic and other anthropogenic activities.
The disadvantages of such activities still remains uncertain; but in the long
run, we know for sure that it would sooner cause major drawbacks to life.
