Mountains
Mountain habitats vary dramatically from the base to the peak of the mountains. On the mountain tops temperatures are colder, oxygen is scarcer, and the sun is harsher. As the climate changes, the plant and animal life between elevations also changes. On the highest mountain peaks the environmental conditions cannot support tree life. The part of a mountain where trees stop growing is called the tree line. Few, if any, trees will grow above this height.
Many animal species live in the lower altitudes, but only the hardiest species can live year round above the tree line, where the air is thinnest and there are no trees.
