FAQs on Audio Notes: स्थलीय पारिस्थितिक तंत्र Video Lecture - पर्यावरण (Environment) for UPSC CSE in Hindi
| 1. What are the main types of terrestrial ecosystems and their characteristics? |  |
Ans. Terrestrial ecosystems primarily include forests, grasslands, deserts, and tundras. Forests are characterized by dense tree cover and high biodiversity. Grasslands are open areas dominated by grasses, with few trees, and support a variety of herbivores. Deserts have low precipitation, extreme temperatures, and specialized flora and fauna adapted to arid conditions. Tundras are cold, treeless regions with short growing seasons, where the ground is often frozen.
| 2. How do human activities impact terrestrial ecosystems? | |
Ans. Human activities such as deforestation, urbanization, agriculture, and pollution significantly impact terrestrial ecosystems. Deforestation leads to habitat loss and reduced biodiversity. Urbanization disrupts natural habitats and increases pollution. Agricultural practices can cause soil degradation and loss of native species. Additionally, climate change, driven by human activities, alters ecosystems, affecting species distribution and interactions.
| 3. What role do terrestrial ecosystems play in the Earth's carbon cycle? | |
Ans. Terrestrial ecosystems play a crucial role in the Earth's carbon cycle by acting as carbon sinks. Plants absorb carbon dioxide (CO₂) during photosynthesis and store carbon in their biomass. Forests, in particular, sequester large amounts of carbon. When trees are cut down or burned, the stored carbon is released back into the atmosphere, contributing to greenhouse gas emissions. Maintaining healthy terrestrial ecosystems is vital for regulating atmospheric CO₂ levels.
| 4. What are some conservation strategies for protecting terrestrial ecosystems? | |
Ans. Conservation strategies for protecting terrestrial ecosystems include establishing protected areas, promoting sustainable land-use practices, restoring degraded habitats, and implementing biodiversity conservation programs. Community involvement and education are also essential for successful conservation efforts. Policies aimed at reducing deforestation, promoting reforestation, and mitigating climate change can further enhance the resilience of terrestrial ecosystems.
| 5. How do terrestrial ecosystems contribute to human well-being? | |
Ans. Terrestrial ecosystems contribute to human well-being by providing essential services such as clean air and water, soil fertility, and resources like food, medicine, and raw materials. They also offer recreational opportunities and cultural benefits. Healthy ecosystems support biodiversity, which is vital for ecosystem resilience and adaptability. Thus, the preservation of terrestrial ecosystems is crucial for sustaining human life and promoting a balanced environment.
