Resources MCQs for Class 8 Exam

Renewable resources are those which get renewed or replenished quickly. for ex- wind energy, solar energy etc.

Natural resources are materials or substances that occur in nature and are utilized by humans for various purposes. They are essentially derived from the environment and can be classified into renewable and nonrenewable resources. Examples of natural resources include air, water, soil, minerals, and sunlight.

Among the given options, option 'C' - Sunlight can be considered as an example of a natural resource. Let's delve into the reasons why sunlight fits the definition of a natural resource:

1. Importance in sustaining life: Sunlight is essential for various biological processes and is a fundamental requirement for the survival of all living organisms, including human beings. It plays a crucial role in photosynthesis, which is the process through which plants convert sunlight into energy to grow and produce oxygen.

2. Energy source: Sunlight is a significant source of renewable energy. Through technologies such as solar panels and solar cells, sunlight can be harnessed and converted into electricity to power homes, industries, and even vehicles. This renewable energy source helps reduce reliance on nonrenewable resources like fossil fuels.

3. Environmental benefits: Sunlight is a clean and sustainable energy source, unlike fossil fuels that release harmful pollutants when burned. By utilizing sunlight as an energy resource, we can reduce air pollution, greenhouse gas emissions, and mitigate the impacts of climate change.

4. Economic value: Sunlight has significant economic value as it can be utilized for various purposes. Besides generating electricity, sunlight is used in industries such as agriculture (for crop growth), manufacturing (solar-powered devices), and tourism (solar-powered attractions). It also supports the solar energy industry, creating job opportunities and contributing to economic growth.

5. Recreation and well-being: Sunlight plays a vital role in human well-being by providing vitamin D, improving mood, and supporting overall health. It also offers recreational opportunities, as people engage in outdoor activities and enjoy the warmth and beauty of the sun.

In conclusion, sunlight is an example of a natural resource due to its importance in sustaining life, its role as an energy source, its environmental benefits, economic value, and its positive impact on human well-being. Utilizing sunlight efficiently and harnessing its potential can contribute to a more sustainable and environmentally friendly future.

The living components of an ecosystem are known as biotic resources. These include human beings, flora, and fauna, fisheries, and livestock. Flora means the plants and fauna mean the animals of the particular area. The ecosystem components interact with each other and are interdependent on each other for their need for survival. Human activities like deforestation and pollution are a significant threat to biotic resources.

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.

Energy generated by using wind, tides, solar, geothermal heat, and nuclear energy are renewable and inexhaustible sources of energy.

Things become resources when they have value. A resource gains its value by how it used or its utility.

Iron is a non-renewable resource that can be recycled. For example, iron chairs, tables, etc. can be recycled after their end utility. But coal and wood, once used, are reduced to ash and smoke, which cannot be recycled further for any use. Water is a renewable resource.

Potential resources are resources whose quantity is not known and are not used in the present.e.g. uranium in Ladakh. They are remaining unused even in the deposits which are found in the region of Ladakh. This resource is known as the potential resource.

Anything that can be used to satisfy human needs is a resource or All the objects in the environment, which are useful to man and have a value, are called "Resources".
