Carbon is eventually returned to the atmosphere through which of the following processes?
A
Polymerization
B
Respiration
C
Photosynthesis
D
Combustion
Verified step by step guidance1
Identify the processes listed: Polymerization, Respiration, Photosynthesis, and Combustion.
Understand that carbon is cycled through the environment in various forms, primarily as carbon dioxide (CO₂) in the atmosphere.
Recognize that Respiration is a biological process where organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct, thus returning carbon to the atmosphere.
Note that Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen, effectively removing carbon from the atmosphere.
Understand that Combustion is a chemical process where organic materials are burned in the presence of oxygen, releasing carbon dioxide and returning carbon to the atmosphere.
