Important Questions for Class 10 Science Chapter 16 – Management of Natural Resources
Below are some important questions for class 10 science chapter 16 – Management of Natural Resources students must study thoroughly.In order to maintain the sustainability of our natural resources, such as forests, wildlife, water, coal, and petroleum, they must be managed in a sustainable manner. With Important Questions for Class 10 Science Chapter 16 – Management of Natural Resources, students learn how we can reduce our impact on the environment by applying the maxim ‘Reduce, Reuse, and Recycle.’ A wide range of stakeholders must be taken into account when managing forest resources. The construction of dams to harness water resources has significant social, economic, and environmental consequences.
Some of the important questions topics for class 10 science chapter 16 – Management of Natural Resources are:
- What is the purpose of managing our resources?
- Harvesting water
- Petroleum and coal
- Management of natural resources
- Forest conservation approaches.
Below are some of the important questions for class 10 science chapter 16 – Management of Natural Resources from an examination point of view.
Class 10 Science Important Questions Chapter 16 – Management of Natural Resources
Q1. What are the reasons for the conservation of forests and wildlife?
Forest and wildlife are very important natural resources. They form a biodiversity hotspot or a location with the greatest amount of biodiversity. They are a significant source of lumber, fuel, leaves, medicinal fruits, and a variety of other things. The preservation of the ecosystem relies heavily on wild species. They play a crucial part in the preservation of the food chain and web.
Q2. Why has it become necessary to look for inexhaustible energy sources?
We should seek endless resources in order to
(a) reduce the strain on finite natural resources.
(b) To lower pollutant levels.
Q3. Name four alternatives to megaprojects like dams.
The four alternatives of the mega projects of damn are:
a)Small holes and lakes are dug.
b)Construction of dykes (a low wall or bank used to keep water out of low-lying areas).
c)Sand and limestone reservoirs are being built.
d)Assembly of water collection units.
Q4. What is GAP? Explain.
The Ganga Action Plan (GAP) was established in 1985 to restore the river Ganga’s quality. To reduce the domestic load on the Ganga under the Ganga action plan.
(a)Interception and diversion are two of the schemes.
(b)Treatment of wastewater
Q5. What are the effects of deforestation?
Effects of deforestation are as follow:-
(a) Extinction of plants, animals, and microbial species.
(b) Endangering indigenous peoples whose culture and physical life are reliant on the forests.
(c) Regional and global climate change, as rainfall declines and drought, becomes more widespread in deforested areas.
(d) Global warming is caused by the release of stored carbon into the atmosphere as carbon dioxide, a greenhouse gas.
(e) A rise in soil erosion and a reduction in soil fertility.
(f) An increase in the number of floods.
Q6. How do advantages of exploiting natural resources with short term gains in mind differ from the advantages of managing our resources with a long-term perspective?
The advantages of exploiting resources with short term aim is to meet the immediate basic human needs. Short term exploitation of natural resources meets the current demand. It is beneficial for the present generation only whereas management of resources with long term perspective is aimed to fulfil the needs of future generations. Long term use of resources can be achieved through their sustainable use.
Q7. Why is sustainable management of natural resources necessary? Out of the two-reuse and recycle-which, in your opinion is better to practise? Give reason.
Sustainable management of natural resources is necessary because:
(i) The resources of the earth are limited and because of the rapid increase in human population, the demand for resources is increasing day by day. Proper management can ensure that the natural resources are used judiciously so that they fulfill the needs of present generation and also last for the generations to come.
(ii) It also takes into consideration long-term perspective and prevents exploitation of natural resources for short-term gains.
The process of ‘reuse’ is better than that of ‘recycling’ because some energy is used to recycle old objects but no energy is required during reuse.
Q8. What is meant by wildlife? How is it important for us?
Life in any form (plants or animals), which exists in its natural habitat is called wildlife. Wildlife is very important for us, as it provides ecological stability by maintaining the food chain. Wildlife is important to us in following ways:
Wildlife is a renewable source of large variety of commercial products like food, fur, lac, musk, leather, feather, ivory, timber, fibre, fodder, fuel, medicines, etc., which can be used from time to time.
Wildlife is considered as gene bank, which can be used for producing high yielding plants and animals through the process of selection and hybridisation.
The wildlife can be used commercially to earn money through tourism (jungle safari, etc.) as it provides best means of sports and recreation.
Q9. Management of forest and wild life resources is a very challenging task. Why? Give any two reasons.
Management of the forest and wildlife resources is considered as a challenging task as there are many stakeholders of forest. These stakeholders are directly or indirectly involved in forest and wildlife resources. These stakeholders are :
- The people who live in or around forests and are dependent on forest products for various aspects of their lives.
- The industrialists who use various forest products and the wildlife enthusiasts who want to conserve the forest and wildlife.
- The Forest Department of the Government which owns the land and controls the resources from forests.
Maintaining the interest of all the stakeholders is a challenging task as:
- Due to industrialisation and urbanisation forest resources are depleting.
- There are profit makers who want to make money from this resource.
Q10. Forests are “biodiversity hotspots”. Justify this statement.
Forests are reservoirs of diversity. They contain different species of plants, animals and all sorts of living organisms. Forests are also under severe threat due to ‘habitat loss, climate change and extensive species loss. Hence, they are considered as biodiversity hotspots.
