They transform material available in our environment into resources and use them. These resources can be classified in the following ways – (a) On the basis of origin – biotic and abiotic (b) On the basis of exhaustibility – renewable and non-renewable (c) On the basis of ownership – individual, community, national and international Fig. 1.1: Interdependent relationship between (d) On the basis of status of development – nature, technology and institutions potential, developed stock and reserves.

As we move inlands towards the river valleys, soil particles appear some what bigger in size. In the upper reaches of the river valley i.e. near the place of the break of slope, the soils are coarse. Such soils are more common in piedmont plains such as Duars, Chos and Terai.
