What Is Hydro Spheric Ecosystem?

Hydro spheric ecosystem is a system in water where living and non living components exchange material and transfer of energy also takes place within water. Salt Water Ocean and sea are the largest ecosystem on the earth about 71% of its surface. Fresh water ecosystem in contrast, covers less than 1%.
Common Features
The unique property of the water lends some common features of aquatic eco system.
Temperature
Water changes its temperature slower than air, so temperature in aquatic ecosystem is more moderate.
Absorption of energy
Although water may appear quit transparent, it absorbs a considerable amount of the light energy that sustain life.
Nutrients
The nutrients in aquatic ecosystem tend to be concentrated near the bottom sediments supporting life where light level often cannot support the photosynthesis.
Abundant water with appropriate temperature
Water is an essential requirement for life; it is available abundantly in the aquatic ecosystem to support life. Appropriate temperature is present in aquatic ecosystem to carry out metabolic processes.
