Answer:
A biome is an enormous ecosystem, spreading over a broad geographic range.
Explanation:
Biomes are classified here in such a form as to get into account their corresponding ranges and similar weather. All climate zones, though, come into one of three essential classifications: tropical and subtropical, temperate, and polar and subpolar.
The first of specific categories is a term covering the area along the equator, spreading north and south by approximately 30 degrees in either direction. In North U.S, this would involve southerly Florida, Texas, and Louisiana. Temperate areas spread from about 30 to 60 degrees on each side of the equator, thus leading in most of America. Ultimately, subpolar and polar regions lie among 60 degrees and the poles, which occur at 90 degrees.
