Why are plants in the alpine biome typically low growing?

The reason why plants in the Alpine biome typically grow slowly s because: They have limited access to nutrients.

Explanation:

To understand this answer we need to analyze all of the options:

a. They have limited access to nutrients. Thanks to the difficulty of life in the alpine zones environment, it doesn't provide enough nutrients for alpine biome to grow faster. That's the reason there is a small number of animals and plants that can survive there.

b. They have limited access to sunlight. This is incorrect because the alpine biome is a type of biome with a high altitude that is better positioned to receive sunlight. Remember that with more altitude the sunlight is stronger.

c. They have too much access to water. This is also wrong because even though alpine biome is really close to snowy mountains. Snow is cold water but cold water freezes instead of providing the fundamental liquid. Also, it is very difficult that rain happens in alpine zones. Thus, this is incorrect.

d. They have access to nutrient-rich soil. This is incorrect because rich soil would make them grow faster, however, is the opposite. They grow slowly because they have limited access to nutrients because life is harsh in those zones.
