AP BIOLOGY

Detailed explanation-1: -The correct response is desert. The desert environment is characterized by low rainfalls (less than 25 cm per year). They are one of the most dry biomes on the planet. The desert biome also has highly variable temperature swings, with high temperatures during the day and low temperatures at night.

Detailed explanation-2: -Deserts are the driest biome, receiving less than 25 cm of rain each year. The land is bare because the soil doesn’t have much organic matter.

Detailed explanation-3: -Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1).

Detailed explanation-4: -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.
