参考答案: D
本题详细解析:
Process I is photosynthesis and shows the capture of energy by phytobpj-h9 i6s, myk- qxp,plankton from the Sun. Process II is respiration, whereby carbon dioxide is released into the atmosphere. Process III shows the movement of carbon when the organisms are eaten by members of the nextxs9 ,piy, kq-p6mh -bj trophic level, and process IV is death and further decomposition of dead organisms by bacteria and other decomposers which eventually causes the release of carbon dioxide (through respiration).
All other choices (Option A, Option B and Option C) do not identify the processes correctly.
