FAQs on Audio Notes: एक पारिस्थितिकी तंत्र के कार्य Video Lecture - पर्यावरण (Environment) for UPSC CSE in Hindi
| 1. What are the primary functions of an ecosystem? |  |
Ans. The primary functions of an ecosystem include the production of food through photosynthesis, the cycling of nutrients, the regulation of the climate, the support of biodiversity, and the provision of habitat for various organisms. These functions are essential for maintaining the balance and stability of the environment.
| 2. How do ecosystems contribute to the carbon cycle? | |
Ans. Ecosystems play a crucial role in the carbon cycle by facilitating the absorption of carbon dioxide (CO₂) through photosynthesis in plants. This process converts CO₂ into organic matter, which is then utilized by animals and microorganisms. Additionally, ecosystems release CO₂ back into the atmosphere through respiration and decomposition, thus maintaining a balance in carbon levels.
| 3. What is the significance of biodiversity in ecosystems? | |
Ans. Biodiversity is vital for ecosystems as it enhances resilience, stability, and productivity. A diverse ecosystem can better withstand environmental changes and disturbances, such as climate change and disease outbreaks. Furthermore, a variety of species ensures the availability of different resources and services, contributing to overall ecological health.
| 4. How do human activities impact ecosystem functions? | |
Ans. Human activities, such as deforestation, pollution, and urbanization, significantly disrupt ecosystem functions. These actions can lead to habitat loss, reduced biodiversity, and altered nutrient cycles, which ultimately compromise the ability of ecosystems to provide essential services such as clean air and water, food production, and climate regulation.
| 5. What role do decomposers play in an ecosystem? | |
Ans. Decomposers, including bacteria and fungi, are essential for breaking down dead organic matter and recycling nutrients back into the ecosystem. They facilitate the decomposition process, which enriches the soil and supports plant growth. This function is crucial for nutrient cycling and maintaining the health of ecosystems.
