The carbon cycle involves a variety of processes that move and convert carbon between Earth systems. The diagram summarizes the
main processes of the carbon cycle.
The carbon cycle is shown as a series of arrows that connect the atmosphere with plants and animals on the surface, as well as dissolved carbon dioxide in the water.
Which pair of events could best be represented by the same arrow in the carbon cycle diagram?
A. A plant performs photosynthesis, and an animal performs cellular respiration.
B. Termites consume a tree trunk, and a tree trunk burns in a forest fire.
C. Humans burn trees to release their energy, and humans burn fossil fuels to release their energy.
D. A plant performs photosynthesis, and carbon dioxide dissolves and acidifies ocean water.
