The tundra is an ecosystem found in the coldest regions of the world, such as Alaska, northern Canada, and parts of Russia. It is primarily characterized by its extremely cold temperatures, permafrost (permanently frozen ground), and low-growing vegetation. Therefore, the tundra is considered to be biotic rather than abiotic.

To determine if the tundra is biotic or abiotic, we should understand the definitions of these terms. Biotic refers to the living components of an ecosystem, such as plants, animals, and microorganisms. Abiotic, on the other hand, refers to the non-living components, such as temperature, precipitation, soil, and sunlight.

In the tundra, there are various biotic components, including vegetation like grasses, mosses, lichens, and shrubs. Many animals also inhabit the tundra, such as reindeer, polar bears, arctic foxes, musk oxen, and migratory birds. These organisms interact with each other and with the abiotic factors of the ecosystem to form a unique and delicate balance within the tundra ecosystem.

Therefore, the tundra is classified as a biotic ecosystem due to the presence of living organisms and their interactions with the environment.
