Trophic relationships in Arctic marine ecosystems

NOAA

Ocean Literacy Principles:

 OLP#4: The ocean makes Earth habitable.
OLP#5: The ocean supports a great diversity of life and ecosystems.

Overview

In this activity, students will be able to describe how ratios of stable nitrogen isotopes can be used to study trophic relationships between marine organisms, make inferences about trophic relationships between organisms and habitats, and compare and contrast organisms in sea ice, pelagic, and benthic communities in terms of feeding strategies and consequent stable nitrogen isotope ratios.
