AP BIOLOGY

Detailed explanation-1: -The desert and the nonforest biome (tundra) are the two biomes that receive the least amount of rainfall during the year. The tundra receives very little precipitation about 6-10 inches annually, mostly in the form of snow, and the desert receives less than 9.9 inches per year.

Detailed explanation-2: -Deserts get about 250 millimeters (10 inches) of rain per year-the least amount of rain of all of the biomes.

Detailed explanation-3: -The Tundra and Desert receive the least amount of precipitation. The Taiga is the world’s largest biome and has evergreen conifer trees such as spruce and fir. The Taiga has cold winters and short cool summers and coniferous needle like trees such as spruce and douglas fir.

Detailed explanation-4: -Deserts are arid ecosystems that receive fewer than 25 centimeters (10 inches) of precipitation a year.

Detailed explanation-5: -Precipitation in the tundra totals 150 to 250 mm a year, including melted snow. That’s less than most of the world’s greatest deserts! Still, the tundra is usually a wet place because the low temperatures cause evaporation of water to be slow.
