Answer:
sun is bigger than earth is 13.9 cm
Explanation:
given data
radius of sun = 700,000 km
radius of earth = 6500 km
to find out
how big is the sun
solution
we know here
scale 1 to 10 billion is
scale = 
so here
we know that scaled diameter = actual diameter × scale .................1
so for earth
scaled diameter of earth = 2 × 6500 ×
scaled diameter of earth = 1.3 × 
and
scaled diameter of sun = 2 × 700,000 ×
scaled diameter of sun = 1.4 × 
so
sun is bigger than earth is 1.4 × - 1.3 ×
sun is bigger than earth is 0.000139 = 13.9 cm

Answer and Explanation:
- the upper boundary of sub alpine ecosystem is known as tree line and lower boundary of sub alpine ecosystem is known is montane zone
- the tree line is the edge of habitat at which trees are capable of growing it is found at very high elevation beyond this there is no life of trees
- the upper montane zone is vegetarian type generally found above the mixed coniferous forest and bellow the sub alpine forest
HOW DOES IT VARIES ACROSS THE STATE :
- the marginal conditions make the sub alpine ecosystem sensitive to environment change
- the long lived nature of the sub alpine species make the zone a good study system
