FAQs on Audio Notes: परिस्थितिकी
| 1. What is the significance of biodiversity in ecology? |  |
Ans.Biodiversity refers to the variety of life forms on Earth, including the diversity of species, ecosystems, and genetic variations. It plays a crucial role in maintaining ecological balance, supporting ecosystem services such as pollination, nutrient cycling, and climate regulation. High biodiversity enhances resilience to environmental changes and provides resources for food, medicine, and economic activities.
| 2. How do human activities impact ecosystems? | |
Ans.Human activities, such as deforestation, pollution, urbanization, and climate change, significantly impact ecosystems. These actions can lead to habitat destruction, loss of biodiversity, and alteration of natural processes. For instance, pollution can contaminate water sources, affecting aquatic life, while deforestation can disrupt carbon storage and lead to increased greenhouse gas emissions.
| 3. What are the main types of ecosystems? | |
Ans.Ecosystems can be broadly classified into terrestrial and aquatic ecosystems. Terrestrial ecosystems include forests, grasslands, deserts, and tundras, each characterized by specific climate conditions and biological communities. Aquatic ecosystems encompass freshwater (lakes, rivers) and marine (oceans, coral reefs) environments, which are vital for supporting a diverse range of organisms and ecological processes.
| 4. What is the role of keystone species in an ecosystem? | |
Ans.A keystone species is one that has a disproportionately large impact on its environment relative to its abundance. These species play critical roles in maintaining the structure of an ecological community. Their removal can lead to significant changes in the ecosystem, often resulting in the decline of various species and disruption of ecological balance. Examples include sea otters in kelp forests and wolves in terrestrial ecosystems.
| 5. How can conservation efforts help restore ecological balance? | |
Ans.Conservation efforts aim to protect and restore ecosystems and biodiversity. Strategies include habitat restoration, protected areas, sustainable resource management, and community engagement in conservation practices. By mitigating the impacts of human activities and promoting biodiversity, these efforts can help restore ecological balance, enhance ecosystem resilience, and ensure the sustainability of natural resources for future generations.
