choose the correct answer from the choices for each question:

1. why cant trees grow above the timberline?

a) the soil is too rich
b) there isnt enough sunlight
c) the conditions are not right for their survival

Explanation:

Above the timberline, environmental factors like extreme cold, strong winds, thin soil, and low moisture create an environment that cannot support tree survival. Options a, b, and d are incorrect: soil is typically poor, sunlight is abundant, and animal populations do not prevent tree growth here.

c) The conditions are not right for their survival
