AP BIOLOGY

Detailed explanation-1: -For most of the year, the tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions.

Detailed explanation-2: -The arctic tundra is cold because higher latitudes receive less solar radiation, especially during winter when the sun can stay below the horizon for more than two months. The alpine tundra, found in higher altitudes such as mountaintops, are cold because the lower pressure allows air to expand and cool.

Detailed explanation-3: -Still, the tundra is usually a wet place because the low temperatures cause evaporation of water to be slow. Much of the arctic has rain and fog in the summers, and water gathers in bogs and ponds. Vegetation in the tundra has adapted to the cold and the short growing season.

Detailed explanation-4: -It’s dry-The tundra gets about as much precipitation as the average desert, around 10 inches per year. Most of this is snow. Permafrost-Below the top soil, the ground is permanently frozen year round. It’s barren-The tundra has few nutrients to support plant and animal life.
