Climate, more than any other single
factor, determines the distribution of life on earth. Climatic boundaries
establish the limits which organisms can survive. Plants, even more than
animals, must be well adapted to climate in order to survive. They cannot move
about or take shelter but must be equipped to endure whatever weather conditions
are likely to occur. In the harsh conditions of the tundra, for example, low
growing mosses, lichens, and a few flowering plants all hug the ground for
shelter from icy winds. Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution. Others, such as bears are flexible enough to adapt to a broad range of climates.
