CBSE Class 10 Science Notes: Chapter 16 – Management of Natural Resources

Resource Conservation: Sustainable use of resources ensures that future generations can meet their needs. This involves reducing, reusing, and recycling materials.
Forest Resources: Forests play an essential role in maintaining ecological balance. Practices like afforestation, reforestation, and controlled grazing are key to conserving forests.
Water Resources: Efficient water management is vital due to the growing demand. Techniques like rainwater harvesting, watershed management, and water recycling can help conserve water.
Energy Conservation: Using renewable sources like solar, wind, and hydropower reduces dependence on non-renewable resources.
Biodiversity: Protecting endangered species and maintaining biodiversity is crucial for ecosystem health.

Understanding and preserving these resources is key to ensuring environmental sustainability.

Most Important Science Class 10 Questions Answers For Board Examination

Here are some of the most frequently asked questions from CBSE Class 10 Science Chapter 16 - Management of Natural Resources:

Define Sustainable Development.
- Sustainable development means using resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs.
What is the significance of water harvesting?
- Water harvesting helps conserve water by collecting rainwater, reducing dependence on groundwater and ensuring water availability during dry periods.
Explain the role of forests in maintaining ecological balance.
- Forests help maintain biodiversity, regulate the climate, control water cycles, and prevent soil erosion.
What are the methods to conserve biodiversity?
- Methods include establishing protected areas, wildlife sanctuaries, and zoos, as well as ensuring sustainable practices in agriculture and industry.
What are the different types of resources?
- Resources are broadly classified into biotic (living organisms) and abiotic (non-living things). They are also categorized as renewable and non-renewable resources.

These questions focus on critical concepts in natural resource management, often addressed in board exams.
