Schematic of the kelp forest food web analyzed. History. Producer  Consumer  -primary -secondary -tertiary Decomposers Kelp forests are characterized by extremely high rates of primary productivity, comprise the base of a complex food web, form a three-dimensional structure that provides physical shelter for many inhabitants, have large algal standing stocks within forests, and export substantial biomass as drift algae that support other coastal ecosystems (Graham et al., 2003; 3. We demonstrate this by linking natural variation in storms with measured changes in kelp forest food web structure in the Santa Barbara Channel using structural equation modeling (SEM). In California's Monterey Bay National Marine Sanctuary the sea otter is a keystone species in the kelp forest ecosystem.
