Science Unit 6: Vocabulary List One tundra desert coniferous forest deciduous forest rainforest grassland aquatic biome habitat environment ecosystem species The coldest of the biomes, located at the top of the world. The soil is frozen. Permafrost, or permanent ice, usually exists within a meter of the surface. Water is unavailable during most of the year.

A few trees may be found along streams, but not many due to the lack of rainfall. Covering nearly 75% of the Earth s surface. Can be broken down into two basic regions as freshwater or marine.
