FAQs on Functions of An Ecosystem Video Lecture - Environment for UPSC CSE

1. What is an ecosystem?
An ecosystem refers to a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their physical environment. It includes both the biological and physical components of a particular area, such as forests, deserts, or oceans.
2. How do ecosystems function?
Ecosystems function through a complex web of interactions between different organisms and their environment. Producers, such as plants, capture energy from the sun through photosynthesis and convert it into food. Consumers, including animals, obtain energy by consuming the producers or other consumers. Decomposers break down dead organic matter and recycle nutrients back into the ecosystem. Additionally, nutrient cycling, energy flow, and various ecological processes contribute to the overall functioning of an ecosystem.
3. What are the benefits of ecosystems?
Ecosystems provide numerous benefits to both humans and the environment. They regulate climate by absorbing and storing carbon dioxide, produce oxygen, and help mitigate natural disasters like floods and erosion. Ecosystems also support biodiversity, which is crucial for maintaining healthy ecosystems and providing essential resources, such as food, medicine, and raw materials. They offer recreational opportunities, cultural values, and contribute to the overall well-being of societies.
4. How are human activities impacting ecosystems?
Human activities have a significant impact on ecosystems. Deforestation, pollution, overfishing, urbanization, and climate change are some of the major threats. These activities lead to habitat destruction, loss of biodiversity, disruption of ecological processes, and degradation of ecosystem services. It is essential to adopt sustainable practices, conservation efforts, and raise awareness to minimize the negative impacts on ecosystems.
5. Can ecosystems recover from disturbances?
Ecosystems have the potential to recover from disturbances, depending on the severity and duration of the disturbance. Some ecosystems have natural resilience mechanisms that allow them to bounce back after disturbances, such as wildfires or hurricanes. However, certain disturbances, like extensive deforestation or pollution, can cause long-term or irreversible damage to ecosystems. Active restoration efforts, such as reforestation, habitat rehabilitation, and conservation measures, play a crucial role in helping ecosystems recover and regain their functionality.
