本题详细解析:
Explanation:
Process I is photosynthesis and shows the capture of energy by phytoplankton from the Sun. Process II is respiration where carbon dioxide is released into the atmosphere. Process III shows the movement of carbon when organisms are eaten by members of the next trophic level, and process IV is the decomposition of dead organisms by bacteria which eventually causes a release of carbon dioxide.
All other choices (Choice A, Choice B and Choice C) do not identify the processes correctly.
