What place is most likely have low biodiversity?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.
Which one system has lowest biodiversity?
The tundra is the biome with the least biodiversity.
Which climate is tundra characterized by?
tundra climate, major climate type of the Köppen classification characterized by sub-freezing mean annual temperatures, large annual temperature ranges (but not as large as in the adjacent continental subarctic climate), and moderately low precipitation.
What terrestrial biome has the highest biodiversity The lowest?
Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.
Why is the tundra dominated by short shrubs and low lying plants?
This biome has plants with root systems that allow the prairie grasses to survive drought, very few trees survive here because of lack of rainfall. This biome has plants that are low lying, evergreen shrubs and small trees.

What is an example of an ecosystem that has low biodiversity?
Example of ecosystem with low biodiversity is definitely a desert. Then there are cold deserts in Antarctica and Gobi basin of central Asia, where biodiversity is minimum. Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America.
What is the most common natural disaster in the tundra?
Wildfires, which can be started by a lightning strike, are one of the most common natural disasters in the tundra. In 2007, a fire started in the North Slope of Alaska by a lightning strike and burned for three months, burning 400 square miles.

What makes the Arctic tundra fragile?
The special conditions that form the tundra make it a very delicate and sensitive biome. Its ecosystems’ structures are fragile, partly because of the low biodiversity and slow growth, and any change can cause long-term impacts.
