Carbon atoms flow through an ecosystem in the carbon cycle, which of the following would result in carbon atoms, moving directly into the atmosphere one fossil fuels being burned to carbon dioxide dissolving in ocean water three carbon dioxide produced through photosynthesis, exiting a plant or for proteins being converted into glucose

Answer 1

The correct answer is option one: Fossil fuels being burned to carbon dioxide. When fossil fuels, such as coal, oil, and natural gas, are burned for energy, they release carbon dioxide into the atmosphere. This is a significant source of carbon that was previously stored underground and is now being introduced into the carbon cycle. The other options describe processes by which carbon moves between organisms and the environment but do not involve direct release of carbon into the atmosphere.
