Sažetak
This study presents the first attempt to classify organisms in the food web of the Adriatic Sea into trophic levels using a nitrogen (δ15N) isotope tracer. Three main trophic levels were identified with significantly different nitrogen values, ranging from primary producers to higher consumers. TL-1 represents plankton and POM samples, TL-2 mostly benthic organisms and TL-3 fishes. The results also indicate the influence of anthropogenic pollution, which significantly increases nitrogen values.
