AP BIOLOGY

Detailed explanation-1: -A biome is a large area characterized by its vegetation, soil, climate, and wildlife.

Detailed explanation-2: -Mountains are found throughout the world and do not fit the definition of a biome because their climate characteristics and plant and animal life vary depending on elevation. Polar regions also are not considered true biomes because they are ice masses and not true land areas with soil.

Detailed explanation-3: -Biomes can be classified into three types, namely terrestrial, freshwater biomes and marine biomes. Terrestrial biomes include grasslands, deserts, tropical forests. Freshwater biomes include polar freshwaters, large lakes, tropical and sub-tropical coastal rivers, temperate coastal rivers and much more.
