FAQs on Ecosystem - Geography Video Lecture - UPSC
| 1. What is an ecosystem and why is it important? |  |
Ans. An ecosystem is a community of living organisms interacting with each other and their physical environment. It includes both biotic (living) and abiotic (non-living) factors. Ecosystems are important because they provide essential services such as air and water purification, nutrient cycling, and habitat for various species. They also contribute to climate regulation and provide resources for human use.
| 2. How are ecosystems classified based on their location? | |
Ans. Ecosystems can be classified into different types based on their location. Some common classifications include terrestrial ecosystems (found on land), aquatic ecosystems (found in water bodies), and marine ecosystems (found in the ocean). Terrestrial ecosystems can further be categorized into forests, grasslands, deserts, and tundra, while aquatic ecosystems can be classified as freshwater or marine ecosystems.
| 3. What are the components of an ecosystem? | |
Ans. An ecosystem consists of various components. The biotic components include plants, animals, and microorganisms, while the abiotic components include air, water, soil, sunlight, temperature, and nutrients. These components interact with each other and form complex relationships that sustain the functioning of the ecosystem.
| 4. How do human activities impact ecosystems? | |
Ans. Human activities have a significant impact on ecosystems. Deforestation, pollution, habitat destruction, overfishing, and climate change are some of the major activities contributing to ecosystem degradation. These activities disrupt the balance within ecosystems, leading to the loss of biodiversity, degradation of habitats, and disruption of ecological processes.
| 5. What are the measures to protect and conserve ecosystems? | |
Ans. To protect and conserve ecosystems, various measures can be taken. These include creating protected areas, implementing sustainable land-use practices, promoting biodiversity conservation, reducing pollution, practicing responsible fishing and forestry, and raising awareness about the importance of ecosystems. Collaboration between governments, organizations, and individuals is crucial in ensuring the long-term conservation of ecosystems.
