They can in many ways including:
- just breathing(CO2 into the atmosphere)
- decomposing after they have died
- burning fossil fuels
livestock like cows can also put carbon back into the atmosphere as they excrete methane gas.
Several processes release carbon as gases (carbon dioxide, carbon monoxide, methane) into the atmosphere. Three important processes are fuel combustion, respiration, and methane release. -- Combustion of carbon-based fuels (wood, alcohol, biogas, or fossil fuels) remove oxygen and combine it to form carbon dioxide and other compounds. -- Plant and animal respiration release carbon dioxide. This is the reverse operation of photosynthesis. -- Methane is released from ruminant animals, from decomposition of organisms, and from ocean-bottom clathrate deposits.
Organisms that break down waste products and dead organisms and return raw material back to the environment are called microbes. Microbes are very important part of our ecosystem. Some fertilizers are unfortunately killing the microbes that actually help our environment. Steps should be taken to minimize use of such chemicals as much as possible.
It could be a good gift if the person that you're giving it to likes to study teeny tiny stuff e.g. micro-organisms. Or if they like collecting them. If they don't like it you should return it and give them the money instead.
If you mean decomposition of biological material, this is mostly done by bacteria which feed off the material.They are always around and will multiply when they find a source of food. Ultra violet rays in the sun's spectrum cause decomposition of many materials, like plastics, paints, rubber etc. Oxidation especially of ferrous metal is also a main cause if exposed to rain (ie rusting). Oxygen and moisture are present in the atmosphere.
Oxygen goes from the lungs through the pulmonary veins to the heart, then through the aorta to various arteries, arterioles, capillaries, and finally end up in the tissues. Oppositely, carbon dioxide moves from the tissues to capillaries, venules, veins, to the heart, then through the pulmonary arteries and to the lungs to be released.
Organisms return carbon dioxide to the atmosphere through the process of respiration. During respiration, organisms break down organic molecules to release energy, producing carbon dioxide as a byproduct that is then released into the air.
Well, honey, let me break it down for you. Ocean atmosphere and organisms are like a dysfunctional family sharing carbon compounds. Phytoplankton slurp up carbon dioxide during photosynthesis, releasing oxygen in return. When these tiny critters die, they sink to the ocean floor, taking carbon with them. It's a wild carbon cycle party down there, darling.
Decomposition.
Decomposition of dead organisms releases carbon back into the atmosphere and soil. Burning of fossil fuels releases stored carbon back into the atmosphere as carbon dioxide. Weathering of rocks can release carbon into the soil and ocean, where it can be stored for extended periods.
People return carbon stored in fossil fuels to the carbon-oxygen cycle by burning fossil fuels like coal, oil, and natural gas. This combustion process releases carbon dioxide (CO2) back into the atmosphere, where it can be taken up by plants through photosynthesis.
The processes that return carbon to the atmosphere include respiration by animals, decomposition of organic matter, and combustion of fossil fuels.
Decomposition breaks down dead organic matter into simple compounds, releasing carbon back into the environment. Respiration also returns carbon to the atmosphere as organisms breathe out carbon dioxide during the process of breaking down food for energy.
The carbon cycle is a process where carbon is removed and returned to the atmosphere. The ways of returning carbon to the atmosphere are- 1. Respiration 2. Decomposition 3. Combustion Ways of removing carbon- Photosynthesis. The CO2 in the air is taken in by green plants for photosynthesis. The green plants die eventually and is decomposed; decomposition return carbon to the atmosphere. Animals respire and return carbon dioxide to the atmosphere. Decomposers respire as well. Green plants can be used to make fuels, which combust to return carbon dioxide to the air.
Photosynthesis is the process that does not return carbon dioxide to the air. During photosynthesis, plants, algae, and some bacteria absorb carbon dioxide from the atmosphere and, using sunlight, convert it into glucose and oxygen. This process effectively reduces atmospheric carbon dioxide levels while producing oxygen, which is essential for the survival of aerobic organisms.
Human beings return carbon dioxide to the atmosphere primarily through the combustion of fossil fuels for energy production and transportation. Additionally, deforestation and land use changes also release stored carbon back into the atmosphere.
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.
Carbon in a producer, such as a plant, is primarily captured through the process of photosynthesis, where carbon dioxide from the atmosphere is converted into organic compounds. When herbivores consume these plants, the carbon is transferred into their bodies as they digest and assimilate the organic matter. This carbon can then move through the food chain as carnivores eat herbivores, and eventually, it can return to the atmosphere through respiration, decomposition, or combustion, completing the carbon cycle.
