The Carbon Cycle

Addition of carbon to the atmosphere
Respiration: Through respiration, carbon dioxide can be added to the atmosphere. Living organisms use respiration to turn food into usable energy. Aerobic respiration requires oxygen to take place, and produces carbon dioxide, releasing it into the air and atmosphere. The energy taken from the food molecules following digestion is used to fuel the organism, additionally when mixed with oxygen, releases carbon dioxide when exhaling.
Glucose + oxygen → carbon dioxide + water (+ ATP energy)

Chemical reaction: Carbon can be released into the atmosphere through chemical reaction. Carbon dioxide in the air dissolves in rainwater to form carbonic acid. Carbonic acid partly forms into hydrogen

This gas added to calcium hydroxide solution produced carbon dioxide. This experiment proved that carbon dioxide was present in seashells. When shells sink to the ocean floor they are eventually turned into sedimentary rocks and as the ocean gets more acidic and its PH drops, the carbon in the shells dissolves.

Short term storage
Forests: After photosynthesis turns carbon dioxide into organic material carbon gets stored in forests for a varying span of time. Trees can sore carbon in their wood and continue to add carbon as they grow. As the tree respires some of the carbon will be returned to the atmosphere, alternatively, some of the carbon could stay in the tree for hundreds of years until it eventually dies and decomposes.
Phytoplankton: Phytoplankton are at the bottom of the marine life food chain. They absorb dissolved carbon dioxide from the ocean and use it to help build their physical body structure. The carbon dioxide is absorbed into the phytoplankton shells. When they die, the carbon stored in their bodys is transported to the deep ocean to then be turned into sediments, or the phytoplankton are eaten by other creatures and their carbon is transported elsewhere in the

    Carbon moves through water and land systems. It is important in CO2 gas which helps regulate the Earth’s temperature. CO2 is also necessary in photosynthesis and aerobic respiration. Fossil fuels and other nonrenewable resources contain carbon. Carbon recycles through the oceans, which is a carbon sinkhole.…

    Shells and bones of marine organisms or any other solids that are drifting in oceans will slowly sink to the sea floor, taking carbon with them. These solids collect on the bottom of the ocean and become part of the long-term store of sediments in the ocean bed. The accumulations of carbon rich matter are physically and chemically changed as they are compressed and buried over a long period of time to form rock limestone. The carbon stored in these limestone sediments will stay locked up for millions of years. The carbon may be released if the sediments rise up to become dry land and expose the carbon rich rocks to…

    Deep-water formation can mix the soil and the deep ocean to create carbon flow4. Both terrestrial and atmospheric carbon cycles can be connected into the oceanic carbon cycle. The oceanic carbon cycle is similar to the terrestrial carbon cycle. Aquatic plants and different types of plankton absorb energy through photosynthesis from the sun and the remaining recycled carbon dioxide in the atmosphere. Carbon dioxide also dissolves into the surface of the ocean and the decaying aquatic organism, which take a short amount of time to breakdown…

    In photosynthesis, the plants use carbon dioxide and light energy and produces glucose and releases oxygen. Carbon dioxide is broken down in the Calvin cycle and is produced into a 3 carbon sugar organic molecule. In step 2, the process is cellular respiration. An animal would eat the organic molecule and break it down and take in oxygen and would produce carbon dioxide and water. The carbon dioxide is produced in the Krebs cycle and is released into the atmosphere in where it can be used for photosynthesis.…

    In atmosphere the concentration of carbon dioxide should be 0.03-0.04% in natural way but due to industries and other sources this percentage is increasing. During photosynthesis plants utilize carbon dioxide to form carbohydrate and release oxygen in presence of sun light. This oxygen in utilized by animals. Carbon serves a dual purpose for organisms, it is a structural component of organic molecules, and chemical bonds in carbon compounds provide metabolic energy. The carbon cycle begins with photosynthetic organisms taking up carbon dioxide (CO2).…

    Ocean productivity depends on the temperatures and nutrients brought to surface from the ocean current. Chlorophyll concentration can change due to temperatures in the ocean and the amount of zooplankton in that area. The global biosphere is an offset of excess carbon dioxide in the atmosphere. Global warming is caused by burning fossil fuels which releases carbon dioxide into the atmosphere. Boreal warming is a decline in greenness indices which is a result of drought, wildfires and insect outbreaks.…

    What Is The Carbon Cycle?

    Carbon can also be added by burning forests, once the timber is alight it will produce CO2. Finally, fossil fuels can also be derived from the sea from the decayed bodies of sea life which is yet another form of addition of carbon to our atmosphere. In terms of removal, plants carry out photosynthesis as part of their respiration process, this involves them taking in carbon dioxide (and water) in order to produce oxygen and glucose. The other method of carbon removal from our atmosphere is “carbon dioxide exchange”, this involves the oceans taking in the carbon dioxide which was in the atmosphere. The colder and rougher the seas are, the more carbon it is able to diffuse and according to the University of Waikato “at present, there is 60 times as much carbon in the ocean as there is in the…

    One of the causes of carbon dioxide released into the atmosphere is from solid waste. However, carbon can be removed from the atmosphere through carbon sequestering. Carbon sequestering is the long-term storage of carbon in ocean, soil, vegetation and geologic formations. Oceans store the most however soil holds 75% of carbon on land and therefore play a leading role in the balance of carbon global cycle (Carbon Sequestration in Soils, 2000). Organic carbon can be lost in soil from accelerated mineralization and erosion (Biala, J., 2011).…

    Co2+ solar radiation+ h2o= Oxogen + Carbon based sugar. Note that oxygen is freed from the Co2 covalent bond and is a direct byproduct of photosynthesis. This carbon based sugar will propagate through the ecosystem and provide latent stored solar energy to other organisms. These other organisms will consume the plant life and convert the simple sugars into complex carbon based…

    The geoengineering projects such as solar shields, ocean fertilization and engineered weathering will help reduce the amount of carbon dioxide released into the atmosphere. Launching solar shields into the orbit could reduce the solar radiation reaching the Earth’s surface by eight percent. Phytoplankton’s serve as a virtual carbon sink. Depositing iron filings in the oceans will encourage the growth of phytoplankton. Thus, reducing carbon.…
