The Mighty Arctic >:D
The north pole is an ocean sized piece of ice, where the temperatures drop so low if you spit you can hear it crackle into ice before it reaches solid ground. When it becomes summer in the southern parts of the Arctic Circle the sun melts away snow and ice to reveal land that during the short summer season is composed of mosses, shrubs, and lichens. Of which the herbivores eat.
The Herbivores include hares, lemmings, and caribou, and in turn the carnivores, which include wolves, bears, and foxes, eat the herbivores.
The plankton in the oceans support a large diversity of the eco-system, this includes the Grey Whales (which are baleen whales) eating habits, these whales also eat crustaceans in the arctic seas.
Grey Whales have the longest migration of any animal, they go on a 14,000-mile journey that takes 2-3 months and begins in their breeding lagoons in Baha California, Mexico.
The largest carnivore on land would be the polar bear, they are also the largest of the bear species. A male grows up to 10 feet tall and can weigh 1700 pounds, a female weighs about half that. Scientists estimate there are about 25,000 left and 60% live in the Canadian arctic.
Polar bears have a special adaptation that allows them to survive the harsh conditions of the arctic, their hair is translucent and hallow which contains air that insulates the bear, its skin is dark and absorbs the suns energy, the bears small ears and tail reduce heat loss.
The bears also have a layer of blubber that gives them buoyancy in water and also helps them stay insulated to keep out the cold, these bears are so insulated that sometimes the only heat that shows up on heat radar is their noses. Their paws are especially adapted to the arctic,the front paws are large to better propel them in water and the back are used to help them steer,the pads are also rought to keep them from slipping on the ice and broad to use like a snow shoe in the snow. Most polar bears eat almost anything but their diet consists mainly of seals,the way they hunt them is they wait at their breathing holes in the ice and attack them when they come up for air.
Phytoplankton,usually microscopic,photosynthectic organisms mot algae and diotoms found in water.

I would have never known that in the summer, ice melts and exposes land, then small plant things grow!!
