This chapter begins with a brief summary of experimental studies that identify the importance of employing interaction webs as a format for further discussion of whales and ocean ecosystems. Next, it develops a crucial aspect of the argument that interaction webs provide a legitimate and useful framework, called “zero-sum ecology”. It invokes a mass balance equilibrium, implying that carbon is not being meaningfully sequestered from or released to global ecosystems over time spans appropriate to current whale ecology. The last section discusses a varied set of studies that collectively suggest that whales, including O. orca, at oceanic spatial scales could have played roles analogous to those demonstrated for consumers of secondary production in much smaller, experimentally tractable systems.

Keywords:   food webs, whales, ocean ecosystems, mass balance equilibrium, carbon, whale ecology, orca whale
