NEET BIOLOGY

Detailed explanation-1: -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: -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: -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: -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.
