Question

poor, rocky soil limits the life forms found in the tundra. in this case, the biosphere is being limited by the

o atmosphere

o cryosphere

o geosphere

o hydrosphere

Explanation:

The geosphere encompasses the Earth's solid parts like soil and rocks. Since the problem mentions poor, rocky soil (part of the geosphere) limiting tundra life (biosphere), the geosphere is the limiting factor. The atmosphere is air - related, cryosphere is ice/snow, and hydrosphere is water - related, none of which are relevant here.

Answer:

geosphere
