This question was picked from No:48 in WAEC 2015 and I chose D, but when I checked it up, found out the correct option was B. This is because as compost maure is added, the yield of fish as well as that of phytoplaktons increases, but this yield growth won't last due to the fact that it will be fed upon by the fish leading to a decrease in phytoplaktons. It was my tutor that explained this to me.
