Ecosystem Paper The south pole is the southernmost point on earth and is located on Antarctica. Because Antarctica is centered on the South Pole it receives very little sunlight, and is the coldest climate on Earth. Most of the life in Antarctica is marine life, such as krill, seals, whales, and penguins. The land is so barren and unforgiving that almost nothing can indefinitely live there. Most of the humans that come to the South Pole are scientists studying the area or tourists. Unlike the North Pole which is basically a frozen ocean, Antarctica is classified as a desert and has giant ice mountains. All of the animals that inhabit Antarctica depend on the ocean, and each other for food and shelter.

The habitat of the South Pole is far too harsh for most organisms to survive. Only in some of the milder areas are some plant life present such as lichen and moss. Penguins are mostly found in the southern hemisphere of the earth, mostly in …show more content…

A keystone species is a species which other species largely depend on. It plays a crucial role in how the ecosystem functions and whether or not the ecosystem will change or cease to exist. In the whole of the Southern Ocean ecosystem, especially in Antarctica, krill is the keystone species. Krill is one of the main food sources of most of the life in Antarctica including penguins, seals, squids, whales, fish, and other species of birds. Krill can live up to six years and is possibly the most abundant species on Earth. Krill’s main source of food is phytoplankton which floats near the surface of the water. Over the past few years krill numbers have decreased and penguins are already foraging for other sources of food. Krill is the main food source of most marine life and terrestrial life in the Southern hemisphere and would affect the ecosystem drastically if
