Biosphere is affected directly by the change in the hydrosphere in a natural way for example: the rain that falls from cloud and again the cloud forms by the evaporation of water from the ocean.
Explanation:
Rain (hydrosphere) falls into the atmosphere from clouds forming the river water and streams in the biosphere.
Plants and animals are dependent over this rain water for their survival in the form of drinking water for their growth.
Water then evaporates from the rivers and oceans forming clouds when water vapor condenses.
In this way living organism are highly affected by the natural process occurred in the hydrosphere.
