Arctic Food Web Arctic Tundra Learn how energy flows in the tundra ecosystem, from producers to decomposers, with examples of organisms and their adaptations. find out the differences between arctic, antarctic, and alpine tundra biomes and their food chains. Learn about the tundra food web, also known as the tundra food chain. discover the producers and consumers in the tundra ecosystem and how they survive in the cold and harsh conditions.
Food Web The Tundra Learn how energy flows through the arctic ecosystem as different organisms eat each other. find out how polar bears, walruses, and other animals fit into the food web and what happens when food is scarce. Food web shifts in our arctic tundra and boreal forest ecosystems were driven almost entirely by an increased use of fungal energy channels by above ground consumers. Legagneux, p. et al. disentangling trophic relationships in a high arctic tundra ecosystem through food web modeling. ecology 93, 1707–1716 (2012). This article reviews the evidence and mechanisms of population cycles in arctic tundra species, especially lemmings, and their role in the plant based food web. it also discusses how climate change may affect the dynamics and consequences of these cycles.
