Natural resources are classified into two types 1. Renewable resources 2.Non- renewable resources Renewable resources: These resources are capable of being regenerated by ecological processes within a reasonable time period. They have the potential to renew themselves. Examples : Soil,water,air.

Examples : House, Road, School etc. Components of environment: The environment consist of the following three components. i) Abiotic or Non-living components ii) Biotic or living components iii) Energy components Abiotic or Non-living components: The Non-living components of the environment are called abiotic components Examples: Air, water, soil, and minerals Biotic or living components : The living components of the environment are called biotic components. Examples : Animals , plants etc.
Energy components : The components of energy flows across biotic and abiotic components which play an important role to maintain the life of living organisms. Examples: Solar Energy, Nuclear Energy, Geochemical Energy etc. Conclusion The environment that is keeping us alive .Without the blanket of environment,we won’t be able to survive. moreover the environments’ contribution to life cannot be repaid.
