Why are there no large trees in the tundra biome?
A
The permafrost prevents deep root growth needed for large trees.
B
High temperatures in the tundra cause rapid tree decay.
C
The tundra soil is too rich in nutrients for trees to survive.
D
The tundra receives excessive rainfall, which drowns tree roots.
Verified step by step guidance1
Understand the tundra biome: The tundra is characterized by extremely cold temperatures, short growing seasons, and a layer of permanently frozen soil called permafrost.
Examine the role of permafrost: Permafrost prevents water from draining and creates a barrier that roots cannot penetrate deeply, which is essential for the stability and growth of large trees.
Analyze the environmental conditions: The tundra has low temperatures and limited sunlight, which restrict plant growth and make it difficult for trees to thrive.
Evaluate the incorrect options: High temperatures do not occur in the tundra, so rapid tree decay is not a factor. Tundra soil is nutrient-poor, not overly rich, and excessive rainfall is not typical of this biome.
Conclude the correct answer: The permafrost is the primary reason why large trees cannot grow in the tundra biome, as it prevents the deep root systems required for their survival.
