Here's why:
* Harsh Conditions: The tundra is characterized by extremely cold temperatures, permafrost (permanently frozen ground), and low precipitation. These harsh conditions make it difficult for many plant and animal species to survive.
* Limited Plant Life: The limited plant life in the tundra is primarily composed of grasses, mosses, lichens, and dwarf shrubs. This lack of plant diversity restricts the number of animals that can thrive there.
* Short Growing Season: The tundra has a very short growing season, which limits the amount of food available for animals.
While the tundra may have a limited number of species, the species that do live there are uniquely adapted to the harsh conditions and play crucial roles in the ecosystem.
