Abstract
This extension activity challenges students to answer hypothetical questions about a marine food web they have created. They are asked to hypothesize what might happen if a top predator like the killer whale became extinct, or if fish from the middle levels of the web were overfished, or if a primary producer such as algae were removed from the web.
