• Resource- everything available in our environment which can be used to satisfy our needs, provided, it is technologically accessible, economically feasible and culturally acceptable can be termed as ‘Resource’.
• Process of transformation of things- interdependent relationship between nature, technology and institutions.
• Resource are a function of human activities.
• Human beings transform material available in our environment into resources and use them.
• Resource as can 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.

      (d) on the basis of status of development - potential, developed stock and reserves.

• On the basis of origin- 

                = biotic resources- obtained from biosphere and have life such as human beings, flora and fauna, Fisheries and livestock etc.

                = abiotic resources- composed of non- living things. Ex, rocks & metals.

• On the basics of exhaustibility -

                 Renewable resources- resources which can be renewed or reproduced by physical, chemical or mechanical process are known as renewable resources.

               = ex- solar & wind energy, water, forests and wildlife, etc.

               = may further be divided into continuous or flow.

                Non- renewable resources- occur over a very long geological time.

               = minerals and fossil fuels are examples.

               = some of the resources like metals are recyclable, fossil fuel cannot be recycled.
