The Arctic tundra ecosystem has a simple food web with polar bears, black wolves, arctic foxes, and brown bears at the top. Reindeer, arctic hares, lemmings, and caribou are primary consumers that feed on producers like moss, lichen, grasses, and other plants. Due to the harsh climate, organisms in the tundra have adaptations like thick fur to retain heat and short statures for plants to maximize sunlight absorption in the low light conditions.
