The biotic and abiotic factors work together to form the alpine tundra and keep the ecosystem working. When one of the factors in an ecosystem or biome changes, it impacts all of the system. Arctic and alpine tundra are areas where trees grow lightly because of the short growing season, low precipitation (rain, snow or hail fall), strong winds, and high altitude. Tundra is often found near long-lasting ice sheets where, during summer, the ice and snow drawback to uncover the ground and allow vegetation to grow. This can happen anywhere on earth.
· Temperature (usually below freezing). If you go up a mountain every 1000 meters the temperature would drop by 10°, for example if you start on the mountain at sea level at 30°C and go up 1000 meters the temperature will be 20°C.
· Precipitation (rain, hail and snow fall). The average precipitation is around 100 inches per year. Most of this precipitation is in the form of snow.
· Seasons (very long winters and short summers). Summer usually lasts from June to September at about 10 to 15 degrees Celsius. In the winter it goes from October to May at below freezing temperatures.
· Altitude (depends on whether it is alpine tundra or arctic tundra). The alpine tundra is at the altitude of 10,000 feet is right below the snow line of the mountains. ．pH level is salinity in the soil
. Cloud attention.
· Angle of sunlight.
· Wind (strong in tundra). Strong winds usually blow at 100 miles per hour.
· Permafrost. Only the top layer of soil thaws during the summer, so trees cannot grow.
· A lot of rocks.
Abiotic factors of the alpine tundra contain low temperatures and high winds. Alpine tundra temperatures range more, but are often below freezing. Water drains more effectively in the alpine tundra than in the arctic tundra. Abiotic factors could affect biotic factors, which are living things, by affecting their ability to survive and reproduce.
· The biotic factors that contain the alpine tundra are living organisms that impact the growth, composition, and structure of the alpine (e.g., insects, herbivores, humans). Also vegatation and symbiotic relationships.
