Which of the following processes releases carbon dioxide to the atmosphere?
A
Dissolution of carbon dioxide in water
B
Combustion of fossil fuels
C
Photosynthesis in plants
D
Nitrogen fixation by bacteria
Verified step by step guidance1
Identify the processes listed in the problem: dissolution of carbon dioxide in water, combustion of fossil fuels, photosynthesis in plants, and nitrogen fixation by bacteria.
Understand the role of each process in the carbon cycle. Dissolution of carbon dioxide in water involves CO₂ being absorbed by water, not released. Photosynthesis in plants uses CO₂ to produce glucose and oxygen, thus removing CO₂ from the atmosphere. Nitrogen fixation by bacteria involves converting nitrogen gas into ammonia, which does not directly involve CO₂.
Focus on combustion of fossil fuels. This process involves burning carbon-based materials, such as coal, oil, or natural gas, which releases carbon dioxide (CO₂) into the atmosphere.
Recognize that combustion of fossil fuels is a major source of CO₂ emissions, contributing significantly to the greenhouse effect and global warming.
Conclude that among the given options, combustion of fossil fuels is the process that releases carbon dioxide to the atmosphere.
