Which of the following statements best describes biodiversity in the Arctic Tundra?

The statement that describes biodiversity in the Arctic Tundra as low biotic diversity is accurate because this biome has relatively harsh environmental conditions that limit the number of species able to thrive there. The Arctic Tundra experiences extreme temperatures, short growing seasons, and permafrost, which impede the growth of many plant species and restrict the range of fauna.

As a result, the number of species—both flora and fauna—present in this ecosystem is lower compared to more temperate or tropical regions. Species that do exist tend to be highly adapted to survive in these conditions, which further emphasizes the limited diversity. Overall, the unique climatic and geographical characteristics of the Arctic Tundra lead to its classification as low in biotic diversity.
