Natural Resources
Resources that are drawn from nature and used without much modification, such as air, water, soil, and minerals.
Biotic and Abiotic Resources
Biotic resources are obtained from the biosphere and have life (e.g., plants, animals), while abiotic resources are composed of non-living things (e.g., land, rocks, minerals).
Renewable and Non-renewable Resources
Renewable resources get renewed or replenished quickly (e.g., solar and wind energy), whereas non-renewable resources have limited stocks and take thousands of years to form (e.g., coal, petroleum).
Sustainable Development
Using resources carefully and judiciously so that they meet the needs of the present without compromising the ability of future generations to meet their own needs.
Resource Conservation
The practice of using natural resources responsibly and efficiently to prevent waste, degradation, and exhaustion.

Frequently Asked Questions
What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally in a short period of time (like solar energy), whereas non-renewable resources exist in fixed quantities and take millions of years to form (like coal and petroleum).
Why is resource conservation important?
Resource conservation is essential because many natural resources are limited in supply. Overuse can lead to their exhaustion, threatening human survival and causing severe ecological imbalances.
How can students contribute to resource conservation in daily life?
Students can conserve resources by saving electricity, turning off taps when not in use, reducing plastic usage, recycling paper, and using public transport or walking.
