The simplest part of the carbon cycle runs the same course as the rock cycle. Carbon is expelled into the atmosphere by volcanic eruptions. This carbon is mostly in the form of carbon dioxide (CO2) and methane (CH4). Carbon dioxide is absorbed by some kinds of rocks as they weather. Weathered rock fragments eventually wash into the sea and settle to the sea floor. These sediments can eventually be compacted and cemented into new rock on the ocean floor. Tectonic movements sometimes lead ocean floors to be pushed deeply under continental plates. When they get pushed deep enough under the earth's surface, heat and pressure eventually cause the rocks to metamorphose and even melt. The cycle completes with another volcanic eruption.
This is the simple form of the carbon cycle mainly because it does not take account of life. But you can see carbon being exchanged between the earth (lithosphere), the air (atmosphere) and the sea (hydrosphere). This part of the carbon cycle existed before the evolution of life (biosphere).
Before adding the complication of "life", we should note that there is also a direct exchange of carbon dioxide between the air and the oceans that actually goes in two directions. Depending on the temperatures the oceans can either absorb and dissolve CO2 or they can release CO2 into the atmosphere. Think about soda pop or other carbonated drinks.
The biosphere (life) adds many more complications to the cycle. Plants (from algae to trees) absorb CO2 from the air (atmosphere) in photosynthesis. Many forms of marine life absorb CO2 from the oceans (hydrosphere) to make their shells. All plants and animals release CO2 into their surrounding environment during respiration. Plants and animals also release their carbon when they die and decay. On land the carbon is released into the air and the soil. On land, burning (combustion) of plant material will also release carbon into the air and the soil. In the sea the carbonate much of the shells of dead animals settle onto the ocean floor and become part of the carbon/rock cycle.
Under certain conditions the sediments formed from dead organisms (mostly plants) can form special metamorphosed materials that we use as fossil fuels. This adds another of life's complications: humans.
Humans are affecting the carbon cycle in many ways. Obviously the burning (combustion) of fossil fuels releases carbon (as CO2) into the atmosphere. CO2 is also released into the atmosphere when limestone is burned to create lime or cement. Humans also affect the carbon cycle through the clearing (deforestation) of land. When trees or burnt or allowed to rot they release CO2 into the atmosphere. Certain types of farming can release even more CO2 into the atmosphere. Rice paddies form artificial swamps that generate methane (CH4), and methane is also produced by concentrated numbers of livestock and poultry.

What else can I help you with?
Is carbon dioxide the only product of the Krebs cycle that is not reused or used in other stages of cellular respiration?
Yes, carbon dioxide is the only product of the Krebs cycle that is not reused or used in other stages of cellular respiration. The other products of the Krebs cycle, such as ATP, NADH, and FADH2, are all used in the electron transport chain to produce more ATP.
What is the continuous movement of carbon from nonliving environment into living things and then back to nonliving?
The continuous movement of carbon from the nonliving environment into living things and back to the nonliving environment is called the carbon cycle. This process involves various stages, including photosynthesis, respiration, decomposition, and combustion, which help regulate the amount of carbon in the atmosphere and maintain the balance of carbon on Earth.
Which of three stages of cellular respiration is a cycle of carbon molecules?
The Krebs cycle, also known as the citric acid cycle, is the stage of cellular respiration that involves a cycle of carbon molecules. It takes place in the mitochondria and involves a series of chemical reactions that produce ATP, carbon dioxide, and high-energy electrons.
What cycle involves photosynthesis and respiration?
No cycle. Transpiration is part of the water cycle, and photosynthesis is what plants do to feed themselves.Carbon cycle involves both of them. Photosynthesis remove Carbon from atmosphere. Respiration release them back
What are the key stages in the pregnancy cycle of humans?
The key stages in the pregnancy cycle of humans are fertilization, implantation, embryonic development, fetal development, and childbirth.
How long does carbon remain in some stages of the cycle?
because

Carbon diocide is released during which stages of cellular respiration?
oxidation of pyruvate to acetyl CoA and the citric acid cycle
Does a chicken has 4 STAGES?
A chicken has 3-stages life cycle, not 4 -stages life cycle
The Calvin cycle includes?
The Calvin cycle includes three main stages: carbon fixation, reduction, and regeneration of RuBP (ribulose-1,5-biphosphate). During these stages, carbon dioxide is converted into sugars using ATP and NADPH generated from the light reactions of photosynthesis.
Which animal has 2 stages of life cycle?
There is no animal that has 2 stages of life cycle. Most animals have at least 3 stages of life cycle.
What are the three stages of cellular respiration and what are the end products?
The three stages of cellular respiration are glycolysis, the citric acid cycle, and oxidative phosphorylation. The end products are ATP, carbon dioxide, and water.
What are the major stages of the water cycle?
The the major stages of the water cycle are precipitation, evaporation, and condensation.
How many general stages in the family life cycle?
There are 5 general stages in the family cycle.
When you exhale what two stages of cellular respiration produce the carbon dioxide you are breathing out?
During cellular respiration, carbon dioxide is produced in both the Krebs cycle (also known as the citric acid cycle) and the electron transport chain. In the Krebs cycle, carbon dioxide is released as a byproduct of glucose metabolism, while in the electron transport chain, carbon dioxide is produced as a result of the breakdown of pyruvate to generate energy.
