A biome is a large area with geographic and climatic similarities as well as similar flora, fauna, and microorganisms. Species living in each biome are adapted to its varying conditions of water, heat and soil. Biomes are classified according to their predominant vegetation. The conservation and preservation of biomes is a major concern to us all.
