SubjectsAgriculture
सतत कृषि
In this Class 9 Agriculture topic from the chapter “Agriculture and Environment,” students learn how farming can meet food needs while protecting natural resources for the future. They explore soil health, water conservation, crop rotation, mixed farming, organic manures, biodiversity and integrated pest management. The topic helps students compare farming practices, understand the effects of excessive chemical use and resource depletion, and evaluate how farmers can maintain productivity while reducing environmental harm through responsible and locally suitable choices.
TOPIC PRACTICE
Up to 4 questions from this page. Select your focus, then start.
An environment-friendly product is designed or selected to reduce harm across relevant stages such as production, use, and disposal. It may use fewer resources, create less pollution or waste, last longer, or be easier to reuse or recycle. No product is automatically impact-free, but causing less environmental damage is the defining idea. The other options describe unsustainable effects.
Resources obtained near the place of use may require less long-distance transport. This can reduce fuel use, transport expense, delivery time, and related emissions, although the exact benefit depends on the resource and production method. The other options state effects opposite to the usual potential advantage.
Using less energy can reduce fuel consumption and associated greenhouse-gas emissions, especially when energy is saved through efficient practices. Growing trees can absorb carbon dioxide and support ecosystems, although planting should be done appropriately for the local environment. Burning waste, wasting fuel, and polluting water create environmental harm, so A is correct.
A sustainable lifestyle uses resources carefully, reduces unnecessary consumption, reuses materials where possible, and limits waste and pollution. These actions help protect ecosystems and preserve resources for future generations. Increased waste, pollution, and irresponsible consumption are opposite to sustainability. Therefore, the conservation and protection described in option A is the main benefit.
