FAQs on Crops variety improvement; why? - Improvement in Food Resources, Force & Laws of Motion, Science, Class 9 Video Lecture

1. Why is crop variety improvement important for food resources?
Ans. Crop variety improvement is important for food resources because it helps in increasing the yield and productivity of crops. By developing new and improved crop varieties, scientists can introduce traits such as disease resistance, drought tolerance, and higher nutritional value. This leads to better crop yields, increased food production, and improved food security for the growing global population.
2. How does crop variety improvement contribute to the Force & Laws of Motion?
Ans. Crop variety improvement does not directly contribute to the Force & Laws of Motion. The Force & Laws of Motion are principles of physics that describe the behavior of objects in motion. However, crop variety improvement can indirectly impact the Force & Laws of Motion by influencing agricultural practices. For example, the development of crop varieties with higher yield potential may require the use of machinery, which relies on the principles of force and motion for its operation.
3. How does science play a role in crop variety improvement?
Ans. Science plays a crucial role in crop variety improvement. Scientists use various scientific techniques and approaches, such as selective breeding, genetic engineering, and biotechnology, to develop new and improved crop varieties. They utilize knowledge from fields like genetics, molecular biology, and agronomy to understand the genetic makeup of crops and identify desirable traits. Through scientific research and experimentation, scientists can enhance crop traits, increase yield, and improve the overall quality of crops.
4. How can crop variety improvement help in addressing the challenges of climate change?
Ans. Crop variety improvement can help in addressing the challenges of climate change by developing climate-resilient crop varieties. Climate change poses threats like increased temperatures, droughts, floods, and pests. By breeding or genetically engineering crops with traits such as heat tolerance, drought tolerance, and resistance to pests and diseases, scientists can help farmers adapt to changing climatic conditions. These improved varieties can withstand extreme weather events, maintain productivity, and ensure food security in the face of climate change.
5. What are the potential benefits of crop variety improvement for farmers and consumers?
Ans. Crop variety improvement offers several benefits for farmers and consumers. For farmers, improved crop varieties can result in higher yields, increased profitability, and reduced vulnerability to pests, diseases, and environmental stresses. They can also reduce the need for chemical inputs such as pesticides and fertilizers. For consumers, crop variety improvement can lead to better-quality and more nutritious food. It can also contribute to lower food prices and increased availability of diverse food options in the market.
