Final answer:
All of the listed terrestrial biomes, including temperate deciduous forest, tundra, desert, and grassland/prairie, are found in the United States. Therefore, the premise of the question is incorrect as none of the options are exclusive outside the U.S.
Step-by-step explanation:
The terrestrial biome that cannot be found in the United States is the temperate deciduous forest. This is incorrect because temperate deciduous forests are indeed found in the United States, particularly in the eastern part. The United States is home to a variety of biomes, including tundra in Alaska, multiple desert biomes in the southwest such as the Mojave and Sonoran deserts, and extensive grassland/prairie regions in the Midwest.
In summary, all of the options listed, A: temperate deciduous forest, B: tundra, C: desert, and D: grassland/prairie, can be found in the United States. Hence, none of the given answers would be correct. The United States boasts an array of biomes due to its vast size and variety of climates.
