Which two processes return the largest amount of carbon dioxide back to the atmosphere?
The two processes that return the largest amount of carbon dioxide to the atmosphere are deforestation, which releases carbon stored in trees through burning and decomposition, and the burning of fossil fuels for energy production, transportation, and industrial activities.
3 ways carbon atoms return to the nonliving part of the carbon cycle?
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.
What process is breathing carbon dioxide?
Respiration. We breathe in oxygen, and return carbon dioxide to the air.
What two processes return carbon from organisms to the nonliving environment?
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.
Explain how people are adding carbon dioxide to the atmosphere?
There is a natural cycle in which animals add carbon dioxide to the air and plants remove it, thus maintaining a stable concentration of carbon dioxide over a very long period of time. Humans are part of this natural cycle. Since the start of the Industrial Age, humans have been adding additional carbon dioxide to the atmosphere, increasing the proportion by around 35 per cent, from 260-280 parts per million (ppm) to the present 380 ppm. We do this by burning fossil fuels, manufacturing cement and by deforestation. We can reduce our impact on carbon dioxide concentrations by reducing and eventually eliminating our consumption of coal, oil and natural gas, by finding alternative processes for cement manufacture, including the capture and sequestration of gas produced, and by ceasing deforestation - even allowing some forests to return.
People return carbon stored in fossil fuels to the carbon-oxygen cycle by burning what?
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.

What process is breathing carbon dioxide?
Respiration. We breathe in oxygen, and return carbon dioxide to the air.
What is the source of the oxygen ?
trees. Trees produce oxygen and in return we give them Co2 (carbon dioxide).
Which process or processes return carbon to the atmosphere?
The processes that return carbon to the atmosphere include respiration by animals, decomposition of organic matter, and combustion of fossil fuels.
What is the source of free oxygen?
trees. Trees produce oxygen and in return we give them Co2 (carbon dioxide).
How does burning fossil fuels hurt the biosphere?
the release of carbon dioxide from fossil fuels and other sources adds to the greenhouse effect, increasing global warming. Fossil fuel pollution can return to earth in the form of acid rain, harmful to our forests and wild life. As well fossil fuels release volatile organic compounds, harmful to our health.

How does fossil fuels burning affect the climate?
The burning of oil, gas and coal has numerous environmental impacts. On a global scale, the release of carbon dioxide from fossil fuels and other sources adds to the greenhouse effect, increasing global warming, which is causing the present climate changes. Fossil fuel pollution can return to earth in the form of acid rain, harmful to our forests and wild life. As well fossil fuels release volatile organic compounds, harmful to our health.
Is the burning of a candle reversible or irreversible?
It's irreversible
