The resources which are available in nature in an unlimited amount are known as inexhaustible resources. These resources can be replenished again and again for use. The solar energy is obtained from the radiations of the sun is an example of an inexhaustible resource. The energy is a safe energy source and does not cause any type of pollution.

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. The forests can be replenished through afforestation. The programs like hugging the tree, tree plantation program, etc have been undertaken in order to increase the forests resources.

Biomass is organic material formed by the decomposition of dead plants and animals. The living forms such as plants and animals can be replenished by reproduction. Hence, biomass is a renewable and sustainable source of energy. It is used to generate electricity or other forms of energy. Thus the correct answer is option D.

They all are fuels because they release heat energy when they are burned. They are fossil fuels because  they were formed from the remains of living organisms millions of years ago.

Resources which get exhausted and are not available in nature in plenty and are known as exhaustible natural resources. They take longer to get replenished. For example coal, petroleum, forest, minerals, etc.

The resources which cannot be replenished again after consumption of resources are known as non-renewable resources. The minerals and metals are obtained from the ores through the process of mining. There are limited reserves of the ores in the Earth's crust.

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. The forests can be replenished again through the process of afforestation. In this method, new trees are planted to cover the area under forests.
