Explain why there are no tall trees in the tundra biome. what are some of the biotic and abiotic phenomena that exist in the tundra?

Tundra is the coldest biome on earth. Tundra got it's name by word "tunturia" which means treeless plains. Tundra biome is characterized by extremely low temperatures, dead organic matter in the nutrient pool and low light intensities. Trees in the tundra biomes are adapted to sweeping winds and nutrient deficiency of soil. These trees are short to resist cold temperatures and falling snow.  

Abiotic factors like temperature is extremely cold, the upper layer of the soil get freezed- permafrozed. Biotic factors like animals go for hybernation because they cannot sustain in cold temperatures.  

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
