The Tundra has many abiotic and biotic organisms including rock, ice, polar bears, and more.
Some biotic organisms are polar bears, seals, fish, and grass during the summer. Biotic things are living organisms. The tundra does not have as many biotic organisms like the rainforest does, but it does have a lot of abiotic organisms. Some of the abiotic organisms are rock, water, sleet, snow, ice, and air.
Biotic Factors: Abiotic Factors:
Polar Bears Rocks
Fish Sleet/Snow Grass (During the summer) Ice
10 Facts about the Tundra
- The Tundra Biome is the 2nd most deadliest environment.
- The Tundra Biome has only 6 weeks of summer.
- There is little to no precipitation.
- The soil has very little nutrients for plants.
- It the least inhabited by humans biome.
- The Tundra Biome is the biome most affected by human pollution.
- The sun is almost 24 hours up a summer day, meaning that there are mostly no nights.
- During the winter, this biome has few hours of sunlight.
- The Tundra Biome is covered permanently by a frozen layer of soil.
- The Tundra Biome is the most vital role in keeping global temperature at a stable place.
Life in The Tundra
The Arctic tundra, where the average temperature is 10 to 20 degrees Fahrenheit (-12 to -6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese and musk-oxen. The summer growing season is just 50 to 60 days, when the sun shines 24 hours a day.
The tundra climate is midway between sub-arctic and ice cap climates. Tundra conditions exist throughout much of Greenland, in parts of Alaska, northern Canada and in northern Russia. Typically, a tundra will only exist between latitudes of 60 and 75 degrees North. The proximity of a body of water also helps form the tundra climate, as it keeps temperatures from dropping even lower. Aside from the extreme temperatures found in the tundra, the precipitation is quite extreme; with only 6 to 10 inches of rain or snow per year, the tundra is as dry as the driest desert.
The Tundra has a lot of plant life within this biome. Some common plants include the bearberry, arctic moss, Caribou moss, Diamond leaf willow, Labrador Tea, Pasque Flower, and the Tufted Saxifrage. The animals in the tundra eat these plants to survive and gain energy to stay warm. Some plants are useful for humans. The plants adapt by growing short and close to the ground to avoid high winds. Hairy stems also keep plants warm in the tundra. The bearberry is a plant with red berries and green leaves. This plant survives in this biome by staying close to the ground to avoid high winds. Hairy stems to help keep safe from the extreme temperatures Owls and birds in the tundra eat the berries on the plant. The bearberry isn't found in any other biome. The bearberry is the most common plant in the tundra.
Animals that live in the tundra have special adaptations that allow them to survive the extreme temperatures and conditions that are present in a tundra. A good example of an animal with special adaptations is the Arctic Fox. The Arctic Fox has short earsand a short, round body with a thick coat to minimize the amount of skin exposed to the frigid air. There is a low amount of biodiversity in the tundra so fluctuations in one animal population will effect populations in another. An example of this would bethat if in a certain year there is a lower amount of Lemmings than usual, then the population of Snowy Owls, who feed mostly on Lemmings, will also decrease.
There are about 1,700 kinds of plants in the arctic and subarctic, and these include:
low shrubs, sedges, reindeer mosses, liverworts, and grasses
400 varieties of flowers
crustose and foliose lichen

How to get water in the tundra
The Arctic tundra is permafrost--ground that is permanently frozen. Because the permafrost has no cracks or pores, nothing can penetrate it--neither plant roots nor water. The surface layer above the permafrost thaws each summer. This layer is called the active layer. Thickness of the active layer depends on its location in the tundra. The more northerly the location, the thinner the active layer is.
How To Survive The Tundra
Think ClearlyIn any survival situation, and particularly one as challenging as a tundra-based one, it pays to stay calm and think clearly and logically. According to the U.S. Field Manual 21-76: "It is more difficult for you to satisfy your basic water, food and shelter needs in a cold environment than in a warm environment. Even if you have the basic requirements, you must also have adequate protectiveclothing and the will to survive. The will to survive is as important as the basic needs." Maintain the will to survive, and act according to a logical plan.ClothingBefore setting out into a tundra or other cold-weather environment, dress properly. You'll need a quality waterproof/breathable jacket and pants. When exercising, you'll constantly perspire regardless of temperature. This perspiration can saturate the wrong types of clothing, making you moist and cold. To prevent this issue, use good base-layer garments that wick your perspiration away and keep you dry. Garments should be made from wool, polyester, treated silk or other suitable materials. Be sure to wear a mid-layer between your base and outer layers to provide ample insulation for the weather. Do not overdress however, as this will increase perspiration and heat loss. Keep your clothes clean and dry.Also, keep your head and hands covered. Wear dark sunglasses (glacier glasses) that protect your eyes from the sunlight and glare off the snow.
