Suresh Reddy answered |
A relatively small amount of ammonia is produced by lightning. Some ammonia also is produced industrially by the Haber-Bosch process, using an iron-based catalyst, very high pressures and fairly high temperature. But the major conversion of N2 into ammonia, and thence into proteins, is achieved by microorganisms in the process called nitrogen fixation (or dinitrogen fixation).
The organisms utilize the enzyme nitrogenase to catalyze the conversion of atmospheric nitrogen (N2) to ammonia (NH3). Plants can readily assimilate NH3 to produce the aforementioned nitrogenous biomolecules. These prokaryotes include aquatic organisms, such as cyanobacteria, free-living soil bacteria, such as Azotobacter, bacteria that form associative relationships with plants, such as Azospirillum, and most importantly, bacteria, such as Rhizobium.

Sanvi Kapoor answered |
The term 'non-renewable' suggests the limited nature of a natural resource. Essentially, the term can be used for any resource that cannot be recovered from the earth readily, after once it has been exhausted. For example: Coal:- it takes thousands of years for coal to form in-between the rocky layers of earth from organic materials that have decomposed. Whereas wind is a renewable resource, it is not limited.

Sahana Patel answered |
Resource is the correct answer.
Explanation:
A resource is anything that can be used to satisfy human wants and has a value. In economics, resources refer to all the factors of production that are used in the production process to create goods and services. Resources can be broadly classified into three categories:
1. Natural resources: These are the resources that are found in nature and can be used in their natural form or after processing. Examples include land, water, air, minerals, and forests.
2. Human resources: These are the resources that are created by human beings through education, training, and experience. Examples include labor, knowledge, and skills.
3. Capital resources: These are the resources that are created by human beings to aid in the production process. Examples include machinery, equipment, and tools.
Resources play a critical role in the economy, as they are used to produce goods and services that satisfy human wants and needs. The availability and efficient use of resources are key determinants of economic growth and development.

Amit Sharma answered |
Due to increasing demand in this fast moving world and rapid industrialization, there is substantial increase in usage of natural biotic resources which are offcourse limited. With increasing the cost of these resources, people started to look after other renewable resources not just because of availability but also to reduce the hazards i.e. Air Pollution, Water Pollution etc. caused by resources like fossil fuels and petroleum. So more the renewable energy got into picture, people started to understand it's importance and as a result due to even low cost these are getting status of actual resources. Summarising in following points to the answer - 1. Limited Biotic Resources 2. Health and Environmental hazards by Nuclear Energy and Pollution 3. Wind Power, Bio Waste and Solar Energy are cheap and renewable. 4. Also these are unharmful to environment.

Ashutosh Iyer answered |
**Pastoral resources** refer to resources that are obtained from the rearing and management of livestock. These resources are derived from the practice of pastoralism, which involves the raising of animals for food, fiber, and other products. Some of the main products of pastoral resources include milk, meat, and wool. Let's discuss each of these products in detail:
**1. Milk:**
- One of the primary products of pastoral resources is milk, which is obtained from animals such as cows, goats, and sheep.
- Milk is a rich source of nutrients and is consumed by humans in various forms such as fresh milk, cheese, yogurt, and butter.
- It is an important source of protein, calcium, vitamins, and minerals, contributing to a balanced diet and overall health.
- Milk can also be processed to produce other dairy products like ice cream, condensed milk, and powdered milk, which have various culinary and industrial applications.
**2. Meat:**
- Another significant product of pastoral resources is meat, which is obtained from animals raised for slaughter.
- Meat is a valuable source of protein, essential amino acids, vitamins (such as B vitamins), and minerals (such as iron and zinc).
- Different types of meat are obtained from various animals, including beef (from cattle), mutton (from sheep), pork (from pigs), and poultry (from chickens, ducks, and turkeys).
- Meat is consumed in various forms, including fresh cuts, processed meats (such as sausages and bacon), and preserved meats (such as dried or smoked meats).
**3. Wool:**
- Wool is a natural fiber obtained from the fleece of sheep and certain other animals like goats and llamas.
- It is a versatile and valuable resource that is used for various purposes, including clothing, textiles, and upholstery.
- Wool fibers have unique properties, such as insulation, moisture-wicking, and flame resistance, making them suitable for a wide range of applications.
- Wool can be spun into yarn or thread, which is then used to create fabrics for garments, blankets, carpets, and other textiles.
**In conclusion,** all three options (milk, meat, and wool) are correct as they are all products derived from pastoral resources. These resources play a crucial role in meeting the nutritional, economic, and industrial needs of human societies, particularly in areas where pastoralism is practiced.
**1. Milk:**

Understanding Non-Renewable Resources
Non-renewable resources are natural resources that cannot be replenished within a human timescale. They are finite and will eventually be depleted as they are consumed.
Examples of Non-Renewable Resources
- Natural gas, which is primarily composed of methane, is extracted from underground reservoirs.
- It is a fossil fuel formed over millions of years from the remains of plants and animals.
- Once consumed, it cannot be replaced within a short period, making it a non-renewable resource.
Comparison with Renewable Resources
- Renewable resources, unlike non-renewable ones, can be naturally replenished.
- Wind energy: Harnessed from wind currents, it can be generated continuously as long as the wind blows.
- Solar energy: Captured from sunlight, it is abundant and available as long as the sun shines.
- Geothermal energy: Derived from the Earth's internal heat, it is sustainable and can be utilized indefinitely.
Conclusion
Natural gas (option 'B') is classified as a non-renewable resource because it takes millions of years to form and is consumed much faster than it can be replenished. In contrast, wind, solar, and geothermal energy are sustainable and can be utilized repeatedly without depleting their sources. Understanding the difference between these types of resources is crucial for sustainable development and energy management.

Niti Banerjee answered |
Explanation:
Unequal Distribution of Resources:
Resources are not equally distributed over the earth. Some regions are rich in resources, while others are devoid of them. This is mainly due to the different natural conditions prevailing in different regions of the world.
Natural Conditions:
The natural conditions, such as climate, topography, soil, and water availability, have a significant impact on the availability of resources. For example, regions with a warm and humid climate are suitable for agriculture, while dry and arid regions may be suitable for mining and oil extraction. Similarly, regions with abundant water resources may have a higher potential for hydroelectricity generation.
Level of Development:
The level of development of a country also affects the distribution of resources. Developed countries have a higher capacity to exploit and utilize resources compared to developing countries. They have advanced technologies and infrastructure to extract, process, and transport resources. This gives them an advantage over developing countries in terms of resource availability.
Technological Levels:
Technological advancements have also changed the distribution of resources. With the advent of new technologies, it has become easier to extract and process resources from remote and inaccessible regions. For example, deep-sea oil drilling technology has enabled the extraction of oil from deep ocean beds, which was not possible earlier. Similarly, advanced mining technologies have made it possible to extract minerals from deep underground mines.
Conclusion:
In summary, the unequal distribution of resources is mainly due to the different natural conditions prevailing in different regions of the world. The level of development and technological advancements also play a significant role in resource distribution. However, efforts can be made to ensure equitable distribution of resources through proper planning, management, and conservation of resources.

The history of colonization reveals that rich resources in colonies were the main attractions for the foreign invaders. It was primarily the higher level of technological development of the colonizing countries that helped them to exploit resources of other regions and establish their supremacy over the colonies.
For example: The teak plantation in South India had destroyed the habitat of several species during that time.
