The biome characterized by low temperatures and low amounts of rainfall is the tundra.

Here's why:

* Low Temperatures: Tundra biomes are found in the Arctic and on high mountaintops, where temperatures remain below freezing for most of the year.

* Low Rainfall: Precipitation in tundra biomes is very low, usually less than 10 inches per year. This is due to the cold air being unable to hold much moisture.
