What process produces carbon dioxide in the atmosphere?
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
What is the biggest contributor to CO2 in the atmosphere?
Global Emissions by Gas Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils.
Where does most co2 come from?
Consumption of fossil fuels accounts for most of the CO2 emissions of the major energy consuming sectors: commercial, industrial, residential, transportation, and electric power.
What is the main source of carbon dioxide?
Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.
Where does most CO2 come from?
How do you produce CO2?
Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread, beer and wine making. It is produced by combustion of wood, peat and other organic materials and fossil fuels such as coal, petroleum and natural gas.
Which process is responsible for removing most of the CO2 from the atmosphere?
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance.
Who produces most CO2 emissions?
China
