• The things directly obtained from nature and are useful to man are called natural resources. Our nature is endowed with innumerable resources such as air, sunlight, wind, trees, water, etc.

• The living resources are called biotic resources and non-living resources are called abiotic resources.

• Resources can be classified as renewable (available at all times) and non-renewable (exhaustible resources).
