Polar Bears and Global Warming

As we humans use fossil fuels, we are causing the earth's temperature to increase and thats what makes global warming occur.

Fossil Fuels are a natural fuel, such as coal or gas.

This global warming based cartoon gives a little hint about what could happen to animals in the arctic. It shows the hot sun which is melting all the ice (wood), the wood is the ice in this picture and then all of the "ice" melted so the arctic animals are surrounded by water.

Global Warming is an increase in the overall temperature of the earth

Ecosystem

A polar bear's ecosystem. The polar bear is the king of Arctic weghing up to 1500 pounds. The polar bear is perfectly adapted to a life on packed ice. Polar bears first decision of food are seals, Ringed and Harbour. However if they are unable o find seals of any kind they will feed on fish, berries, seabirds, plants and other scraps.

An ecosystem is a biological community of interacting organisms and their physical environment.

(Above)A food web is a system of interlocking and interdependent food chains.

A carnivore is an animal that feeds on flesh

Polar bears are the largest land carnivores in the world, rivaled only by the Kodiak brown bears of southwestern Alaska. Polar bears sit at the top of the food chain in the biologically rich Arctic. The most carnivorous of the bear species, polar bears feed primarily on the fat of ice-dependent seals. The remains of these seals provide food for many other Arctic wildlife species, giving polar bears a vital role in their ecosystem
