Natural resources are useful raw materials that we get from the Earth. They occur naturally, which means that humans cannot make natural resources. Instead, we use and modify natural resources in ways that are beneficial to us. There are different ways to classify natural resources, including where they come from and if they are renewable or not
Biotic and Abiotic Natural Resources

If natural resources come from living things or organic materials, then they are considered biotic resources. Biotic resources include plants, animals, and fossil fuels. The three fossil fuels are coal, oil, and natural gas. Fossil fuels are classified as biotic resources because they were formed from the decay of organic matter over millions of years.

On the other hand, abiotic resources originate from nonliving and inorganic materials. For example, air, sunlight, and water are abiotic natural resources. Minerals (gold, copper, iron, diamonds) are also considered abiotic.

Hello everyone,

I am here to give a brief talk on natural resources. Natural resources are naturally existing materials in our environment naturally, particularly without human interference. Natural resources include a region's minerals, energy, land, water, forests, wildlife and biodiversity. They can be classified into renewable and non-renewable resources.A non renewable resource is such that cannot be renewed by itself or replenished as it gets used. An important example of this is carbon based organically derived fuel. Renewable resources are those which can be replenished as it gets consumed or used up. Water is a great example for this. We can easily understand this by thinking about the water cycle that replenishes the water on earth and that fossil fuel is becoming scarce and scientists are experimenting with other forms of energies to run motor vehicles. The natural resources can be again classified into biotic and abiotic resources, on the basis of origin. Minerals, metals and other such  non-living materials  fall in the category of abiotic natural resources.The biotic resources can be obtained in the raw form, or by means of cultivation through agriculture. Petroleum is a resource included in this category; the organic origin or petroleum is the reason behind its inclusion in biotic resources. Crops obtained through farming are also  important natural resources. we need to take care of not wasting our resources and must learn to make use of them in an effective manner so that they last longer and be useful for our future generations also. Thank you
