Define Resources and give some examples.
Things available in our environment become resources only when human beings find a way to transform them into a useful form. For a thing to become a resource:
Resources can be classified based on their origin, exhaustibility, ownership and status of development.
Resources can be living or non-living. Living things, like forests, land and sea animals, insects and human beings, are called biotic resources.
Resources in the form of non-living things, like rocks, minerals and metals, are called abiotic resources.
Resources can also be classified based on whether they can be regenerated or lost forever once used.
Resources like solar and wind energy, reversible chemical reactions and physical power, which can be regenerated once used, are called renewable resources.
