| 1. What are some of the challenges faced by living in the desert? |  |
Ans. Some of the challenges faced by living in the desert include extreme temperatures, lack of water, limited food sources, and the threat of sandstorms. These conditions make survival and basic activities such as agriculture and infrastructure development difficult.
| 2. How do plants and animals adapt to survive in desert environments? | |
Ans. Plants and animals in desert environments have developed various adaptations to survive. For example, some plants have deep root systems to reach groundwater, while others have thick waxy coatings on their leaves to reduce water loss. Animals may have water-conserving behaviors, such as being active at night and seeking shelter during the day to avoid the intense heat.
| 3. Can people in the desert rely on groundwater as a source of freshwater? | |
Ans. Yes, people in the desert often rely on groundwater as a source of freshwater. However, it is important to manage and use this resource sustainably to prevent depletion. Over-extraction of groundwater can lead to the drying up of wells and the emergence of ecological and socio-economic issues.
| 4. What are some of the economic activities that take place in desert regions? | |
Ans. Some economic activities that take place in desert regions include tourism, mining, and agriculture. The unique landscapes and natural attractions of deserts often attract tourists, while mineral resources such as oil, gas, and minerals are extracted through mining operations. In certain desert regions, innovative agricultural techniques such as drip irrigation and greenhouse farming are used to cultivate crops.
| 5. How do desert ecosystems contribute to global biodiversity? | |
Ans. Desert ecosystems contribute to global biodiversity by supporting unique and specialized plant and animal species. These species have evolved specific adaptations to survive in the harsh desert conditions, making them valuable in terms of scientific research and conservation efforts. Additionally, desert ecosystems often act as migration corridors for wildlife, connecting different habitats and facilitating the movement of species across larger landscapes.
