    Polar ecosystem, complex of living organisms in polar regions such as polar barrens and tundra.. Polar barrens and tundra are found at high latitudes on land surfaces not covered by perpetual ice and snow. These areas lying beyond the tree line comprise more than 10 percent of the Earth’s land surface. Most are in the Arctic and subarctic, as little land area in the Antarctic is ever free of. Dynamics of Ecosystems. Contents: Explain the process of natural selection and cite evidence for the process. Describe the ways in which evolution influences biodiversity. Discuss reasons for species extinction and mass extinctions events.

Polar marine ecosystems have long been recognized as being rich in top predators (seabirds, seals, and whales). In the Arctic, the important top predators are seabirds (especially alcids and gulls), Harp and Hooded seals, and the smaller toothed whales, although in the past baleen whales were also important.

The polar regions of the world are always cold because at these high latitudes, the sun never rises far above the horizon, and its rays only glance across the earth.

What little solar energy does manage to reach the surface is reflected back into space by the bright white ice. Crash Course Kidsviews.
