What are the parts of the tundra ecosystems?
The details will depend on which tundra ecosystem one is referring to, but tundra ecosystems are characterized by cold temperatures, little precipitation, and no trees.
Tundras are found in the Arctic and above the treeline on very high mountains. There are three general categories of tundras: alpine, Arctic, and Antarctic.
Areas classified as tundra are purple in the image below.
Tundras are characterized by cold temperatures, little precipitation, a short growing season, and no trees. Tundras also experience freeze and thaw cycles, as opposed to polar regions which are always frozen.
Plants found in this ecosystem include shrubs, mosses, grasses, and lichen. Animals include mountain goats, pikas, voles, caribou, arctic foxes, elk, and others.
Arctic tundra is characterized by permafrost, permanently frozen subsoil. In contrast, alpine tundra does not have permafrost and has well-drained soil. The tundra in Antarctica has more available water and thus slightly higher primary production than the Arctic tundra but no terrestrial mammals.

The tundra ecosystem consists of several distinct parts:
-
Permafrost: A layer of permanently frozen subsoil that underlies much of the tundra.
-
Tundra vegetation: Low-growing plants such as mosses, lichens, grasses, and shrubs that are adapted to the cold and harsh conditions of the tundra.
-
Animal life: Includes a variety of species adapted to the cold climate, such as caribou, musk oxen, arctic foxes, polar bears, migratory birds, and insects.
-
Bodies of water: Tundra ecosystems may contain lakes, rivers, and ponds, which support aquatic life such as fish, amphibians, and aquatic invertebrates.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
