  • Using Na15NO3 and 15SNH4Cl as tracer, we studied the transfer of 15N along the food chain composed of organisms such as Platymonas subcordifwmis, Anemia saliva, Perwt;u perdcillatus and Liza carinatus.The abundance and atomic percentage of 15N in each organism, as well as the transfer of 15N among different biological phases were measured.Results show that, in the nutrient transfer from low level to high level along the food chain in the media of 15SNH4Cl, the transfer rate of Anemia salivaLiza casinatus exceeded 3% and was higher than that in Na Na15NO3;the accumulation of 15N in the bodies of Lira carinatvs with 15SNH,Cl as media was also higher than that with Na Na15NO3 as media.
