Detailed explanation-1: -There are two types of tundra: arctic and alpine. The tundra does not have much biodiversity and vegetation is simple, including shrubs, grasses, mosses, and lichens. This is partly due to a frozen layer under the soil surface, called permafrost.

Detailed explanation-2: -Low species diversity : The tundra biome has the least biodiversity, but the northern coniferous biome also has low species diversity. Generally speaking, desert biomes have low species diversity, but pockets of localized high biodiversity do exist.

Detailed explanation-3: -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-4: -San Marino Is The Least Biodiverse San Marino came in last in our study of biodiversity, with only 758 total plant and wildlife species, this tiny microstate certainly lacks a wide range of plants and animals. Why is this?

Detailed explanation-5: -The biodiversity of tundra is low: 1, 700 species of vascular plants and only 48 species of land mammals can be found, although millions of birds migrate there each year for the marshes. There are also a few fish species. There are few species with large populations.
