Land, water and winds are the three natural systems of Ecospheres. They are of solid, liquid and gaseous forms. They may be called the non-living. Besides these, there is a fourth sphere consisting of the flora and fauna. This is called the biosphere. This may be alternatively called the living systems. Between the living and the non-living systems, there are various interactions. Several environmental changes occur on the earth in response to these interactions.

‘Place’ is an important concept in geography. ‘People’ are the most characteristic component of that place. Hence, of all ecosystems, human ecosystems have greater importance and value. It is for this reason this ecosystem is shown at the top of all the ecosystems.
