Carbon and nitrogen stable isotope ratios in organisms are generally considered to be a useful tool as natural tracers to analyze organism' s food sourcesl), 2). Generally at each trophic transfer of food energy, carbon stable isotope ratios increase by 0 2 %o, whereas nitrogen stable isotope ratios increase by 3 5 %o 3>,4>. The food ingested by deposit feeder is consisted of deposit organic matters assemblaging many kinds of organic matters from different origin. It is very difficult to… CONTINUE READING
