A variety of different mechanisms in nature help create diversity in organism populations. The tundra found in the northernmost parts of the planet is the world’s youngest biome. The tundra is home to a variety of plants and animals. Organisms that can be found in the tundra include shrubs, mosses, caribou, polar bears, and wolves. Which mechanism do the different organism populations found across the tundra exemplify?

The correct answer is species diversity.

Explanation:

Tundra refers to the ecosystem, which is found on the top of the mountain and in Arctic regions. It is the treeless region, where the rainfall is scant or negligible and climate is windy and cold throughout the year. However, despite the harsh conditions, the number of species found in the tundra ecosystem is quite high.  

One can witness various kinds of organisms of distinct species in the region, thus, making it one of the diverse regions on the surface of the Earth. The mechanism, which is accountable for such species richness in the tundra region is the species diversity, which is illustrated as the entire sum of species found within a given community.
