With growing population consumption of natural resources is also increasing. With the increasing industrialisation and urbanisation, we need to conserve natural resources as their destruction will also upset the ecological balance. The wise use of the earth's resources by humanity is called Conservation of natural resources. It is the proper management of a natural resource to prevent its exploitation, destruction or degradation.

Option D is correct answer.  Ocean resources within 200 nautical miles are called as national maritime resources. Whereas, 200 nautical miles are called as international resources.

Resources can be conserved by following few mantras :

Reduced using: use only how much is essential and not waste the rest.

Reusing: it is nothing but using one product again and again till it loses purpose of existence.

Recycle: it is nothing but completely destroying the resource and converting into new materials and objects. 

Community property resources are natural resources owned and managed collectively by a community or society. Pastures or grazing lands is one of the example. Rivers, Lakes, oceans are the other examples.

Land, soil and water are the basic resources required for agricultural activities. Of the given options, only wind is not needed for agriculture.

The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as renewable or replenishable resources. For example, solar and wind energy, water, forests and wildlife, etc.

Non-renewable: These are the sources that cannot be renewed and are available in limited quantities. Examples include coal, nuclear, oil, and natural gas.

As thermal electricity cannot be renewed if used once, it is a non-renewable source of energy.

The process of transformation of things available in our environment involves an inter- dependent relationship between nature, technology and institutions. Human beings interact with nature through technology and create institutions to accelerate their economic development. 

All those things which are composed of non-living things are called abiotic resources. For example, rocks and metals.

 Resources that are found everywhere like the air we breathe, are ubiquitous. 

The major energy sources are fossil fuels such as coal, petroleum and natural gases. They are an important source of energy for the modern technology. Fossil fuels are used in industry, thermal plants, agricultural operations, automobiles etc.

Things become resources only when they have a value. “Its use or utility gives it a value. All resources have some value.” 

Among the given options iron and cotton have an economic value. Man, when educated, has value. But the grass has no such direct value.

1: Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. Examples of non renewable resources are coal, crude oil etc. Examples of renewable resources are air, water, natural gas, wind, solar energy, etc.
2:The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as renewable or replenishable resources. For example, solar and wind energy, water, forests and wildlife, etc. 

3: Non-renewable resources occur over a very long geological time. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some like fossil fuels cannot be recycled and get exhausted with their use

All those things which are composed of non-living things are called abiotic resources. Fish is a living being. Hence, it is a biotic resource.

Among the given options, buildings are made by human beings for their own use.

On the basis of ownership resources are classified as follows:

• Individual resources are owned by an individual. Example - land owned by a farmer.
  
• Community resources are owned by a community. Example - graveyard, parks, ponds etc
  
• National resources are owned by a nation's government. Examples - roads, railways etc.
  
• International resources like oceans and seas are regulated by international bodies.
  

• Environmental resources are those resources which are the elements of environment.
  

These are of different types like:

• Socio-economic resources which includes farms, parks, etc.
  
• Cultural resources like archaeological sites.
  
• Natural resources like plains, soil, vegetation and wildlife.
  

People can make the best use of nature to create more resources when they have the knowledge, skill and the technology to do so. Education helps in making human into a resource. For example scientists developed technology to harness solar energy. 

• On the basis of ownership resources are classified as follows:
  
• Individual: Resources owned by an individual. Example-land owned by a farmer.
  
• Community:  There are resources which are accessible to all the members of the community. 
  
• Pond can be owned by a community (villagers) and also by an individual.
