This nice site from NOAA starts with a bold statement: "Big fish eat little fish; that's how the food cycle works." It's a fitting introduction to this exploration of aquatic food webs. Offered as part of NOAA's main Education Resources site, this site offers a dozen well-produced videos, lesson plans, and data sets divided into areas that include Background Information and Multimedia. These items include "Tagging of Pacific Pelagics," "Census of Marine Life Biodiversity," and "Components of a Food Web." Visitors can also look over the Features area near the bottom of the site, whose offerings range from a profile of the Stellwagen Bank National Marine Sanctuary to a longitudinal study of sea trout in the food web. Finally, visitors can use the social media tabs to share resources from the site with colleagues and others.
