Detailed explanation-1: -Biodiversity in the tundra is low and dominated by mosses, lichens, and low-growing perennial shrubs. The tundra biome contains only about 3% of the world’s flora.

Detailed explanation-2: -This is consistent with the Arctic tundra biomes worldwide. They have the least biodiversity of any of the world’s biomes. This is likely due to the cold temperatures and precipitation, which can inhibit the growth of many plants and trees.

Detailed explanation-3: -The terrestrial biome with the lowest biodiversity is the tundra. The tundra is located at the northern most and southern most poles of the Earth. This area is extremely cold with limited precipitation.

Detailed explanation-4: -Arctic tundra is relatively homogeneous and with low biodiversity due to its recent glacial history, while alpine tundra is much more diverse and with higher biodiversity mostly because of its fragmentation on isolated mountains.

Detailed explanation-5: -The growing season is short, with only 50 to 60 days per year when temperatures are high enough for plants to grow. Biodiversity is also low, compared to most other biomes, as not many species are able to adapt to survive in the tundra.
