The Carbon Cycle is a major component of the Biogeochemistry of the planet. Across the Lithosphere and Biosphere, carbon plays a large role in the creation of biomass as well as decomposition. The carbon cycle in the hydrosphere, particularly in the oceans, is not as well known. We do know, however, that oceans play a critical role in the carbon cycle because it acts as a large sink of carbon as it is rapidly exchanged with the atmosphere. The carbon cycle in the oceans involves both organic compounds and inorganic compounds.
The acid is decarboxylated inside the bundle sheath cells and the CO2 is concentrated inside these cells. Rubisco is flooded with CO2and sugars are made in abundance using the Calvin cycle. Concentrating carbon dioxide in the bundle sheath cells minimizes photorespiration. The carbon cycle is important in ecosystems because it moves carbon, a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans. If the balance between these latter two reservoirs is upset, serious consequences, such as global warming and climate disruption, may result.
The Environmental Issues Raised by the Disturbance of the Natural Balance in the Level of Atmospheric Carbon Dioxide In this essay I will be discussing what the Natural Balance is and what affect this is having on the Carbon Cycle. The balance between Photosynthesis and Respiration. The three main problem affecting the level of atmospheric Carbon Dioxide; Deforestation, World Population and Burning Fossil Fuels. The Natural Balance is the Balance between photosynthesis and Respiration. Photosynthesis is when plants use the energy from the sun to produce food for all animals and then turn it into glucose.
The other three percent is divided amongst the two percent ice and one percent fresh water. Making earth’s waters composed mostly of salt water. Salt water covers most of our planet indicating climate change to have a giant impact on our oceans. Taking a closer look at the ocean and our water in general can reveal several clues to the greater effects of climate change and what other ways climate change can affect our planet. (2) When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced.
Cellular respiration takes glucose molecules and combines it with oxygen. This energy results in the form of adenosine triphosphate (ATP), with carbon dioxide and water that results in a waste product. Photosynthesis uses carbon dioxide and combines it with water,
Through the process of photosynthesis, green plants absorb light by use of chlorophyll which converts carbon dioxide to carbohydrates thereby absorbing carbon dioxide in the atmospheric region. Energy from the sunlight + 6CO2 (g) + H2O (l) → C6H12O6 + 6O2 (g). Animal undergoes respiration which is the process of breaking down of sugar to produce energy that is needed for growth and reproduction process. During the process of respiration carbon dioxide is produced as a byproduct. Also when animal and plants die they decompose to form fossils fuel which when burnt they release carbon dioxide into the atmosphere.
Cellular respiration is the chemical process that generates energy by breaking down food molecules when oxygen is present (Prentice Hall). The chemical equation of cellular respiration is 6O2 + C6H12O6 6CO2 + 6H2O + Energy, meaning the reactants of cellular respiration are oxygen and glucose while the products are carbon dioxide, water, and energy (Gregory). Cellular respiration is crucial to life because it provides all cellular processes with the energy needed in order to function. This process involves glycolysis, the Krebs Cycle, and the electron transport chain (Dr. Fankhauser). Glycolysis, which occurs in the cytosol of the cell, is the anaerobic catabolism of glucose that leads to the release of energy and the production of two molecules of pyruvic acid (Gregory).
The main points I am going to look at is how the ocean and plants affect the removal of carbon in our atmosphere through the process of photosynthesis, and how the carbon is added back to the atmosphere from the burning of fossil fuels. What is photosynthesis? Photosynthesis is the chemical process of plants, and some bacteria, both on land and in the ocean, that take carbon dioxide (CO²) from the air and using the light from the sun to create glucose, their source of food and oxygen, which we need to breathe. All green plants can photosynthesise because they have chloroplasts, which is the green pigment which attracts the Carbon Dioxide in the air. Photosynthesis happens in the plant leaves because it is there where the stomata’s are.
("Photosynthesis - Biology-Online Dictionary") This process can be simplified in this equation: 6CO2+12H2O+energy=C6H12O6+6O2+6H2O. It means photosynthesis is a process in which carbon dioxide (CO2), water (H2O) and light energy are utilized to synthesize an energy-rich carbohydrate like glucose (C6H12O6) and to produce oxygen (O2) as a by-product.

Processes such as photosynthesis, combustion and the compression of the earth play key roles in changing, containing and releasing carbon. All the chemical reactions and processes and forms carbon creates are part of the carbon cycle, which is one of the most important cycle on earth. The majority of carbon on earth is in the atmosphere the rest is stored in rocks, fossil fuels, oceans, plants and soil. Carbon is constantly being added to the atmosphere, the most common forms being carbon dioxide and methane gas. At the same time it’s being removed by plants on land and in the oceans.
