Describe the path from biosphere to biome to ecosystem. Define biome as a large region characterized by a specific type of climate and certain types of plants and animals. Plant life which grows in a specific region are characteristic of that region and have adapted to life there. They must adapt to a climate which is hot or cold, wet or dry, high altitude or low altitude , high latitude or low latitude. The adaptions include linear size and plant size, shape and color. Outline how the biome can change as the altitude increases, from grasses and shrubs, to deciduous trees, to conifers, and eventually snow caps.
