Question

Features of high altitude trees

Answer 1

Fewer trees survives at high elevation and less energy is infused into soil through decaying matter.  

Fewer stretches of soil are open sources of nutrients for tree growth.  

Effect is wide spacing between patches of trees seen at lower altitudes.

Scientists hypothesized that once tree gets old and tall it becomes difficult for tree to pull water to the top because of downward pull of gravity.  

Gravity's pull reduces turgor and thats why trees stop growing.
