Smaller herbivores, such as snowshoe hares and voles, depend on the understory vegetation, forming a crucial link between the plants and the carnivores that follow them in the chain. Caribou and moose browse on woody shrubs during the winter, while salmon rely on marine-derived nutrients after spawning.

Similarly, salmon are not just a food source; their carcasses deliver oceanic nitrogen to forests, directly feeding the trees that provide oxygen and shade. Alaska’s food chain represents one of the most dynamic and fragile balances of predator and prey on the planet.
From the nutrient-rich waters of the Bering Sea to the vast tundra of the interior, every organism, from the smallest plankton to the largest brown bear, plays a specific role. These microscopic algae perform photosynthesis, converting sunlight into energy and forming the primary production that fuels the entire oceanic system.

The iconic brown bear, however, sits at a unique nexus, acting as both a formidable predator of fish and a scavenger that redistributes marine nutrients far inland after consuming salmon.
