- Abiotic Factors: The tundra is distinguished by extremely cold temperatures, permafrost (permanently frozen subsoil), short growing seasons, low precipitation, strong winds, and long, dark winters with limited sunlight.
- Plants: Common plants in the tundra include mosses, lichens, grasses, sedges, dwarf shrubs, and small flowering plants like Arctic poppies and cottongrass.
- Plant Adaptations: Tundra plants grow close to the ground to avoid wind and retain heat, have shallow root systems due to permafrost, develop small leaves to reduce water loss, and often have dark pigments to absorb more solar radiation.
- Animals: Animals found in the tundra include caribou (reindeer), Arctic foxes, snowy owls, lemmings, musk oxen, polar bears, and Arctic hares.
- Animal Adaptations: Tundra animals have thick fur or feathers for insulation, compact bodies to minimize heat loss, seasonal camouflage (e.g., white winter coats), fat layers for energy storage, and behaviors such as migration or hibernation to survive harsh winters.
