Hello

Resource can be defined as-

Anything which is present in our environment that we can use for our own benefits or gain is considered to be a resource. Keeping in mind that it should be easy to extract, cost efficient and easy to use. There are 2 types of resources- renewable and non- renewable resources.

Resources which can be replenished over time are considered as renewable resource as we can understand from it's name. For eg- wind, water, solar energy

Whereas, resources which cannot be replenished over time and once over cannot be renewed are known as Non renewable resources. Eg- fossil fuels, gas, petroleum.

I hope this answer helps you.

All the best
