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

1. What are the primary functions of an ecosystem?
Ans. The primary functions of an ecosystem include energy flow, nutrient cycling, habitat provision, and biological regulation. Energy flow refers to the transfer of energy through food chains, while nutrient cycling involves the movement of nutrients through biotic and abiotic components. Ecosystems also provide habitats for various organisms and regulate populations through predation, competition, and symbiotic relationships.
2. How do ecosystems maintain biodiversity?
Ans. Ecosystems maintain biodiversity through complex interactions among species, including predator-prey relationships, mutualism, and competition. These interactions create various niches, allowing different species to coexist and adapt to their environments. Biodiversity contributes to ecosystem resilience, enabling it to withstand environmental changes.
3. What role do producers play in an ecosystem?
Ans. Producers, primarily plants and phytoplankton, play a crucial role in ecosystems by converting solar energy into chemical energy through photosynthesis. They form the base of the food chain, providing energy and nutrients to herbivores (primary consumers) and, subsequently, to carnivores (secondary consumers). This energy transfer is essential for the functioning of the entire ecosystem.
4. How do human activities impact ecosystem functions?
Ans. Human activities such as deforestation, pollution, and urbanization significantly impact ecosystem functions by disrupting natural processes. These activities can lead to habitat loss, decreased biodiversity, and altered nutrient cycles. The consequences often include reduced ecosystem services, such as air and water purification, climate regulation, and food production.
5. What are ecosystem services, and why are they important?
Ans. Ecosystem services are the benefits that humans derive from ecosystems, including provisioning services (food, water), regulating services (climate regulation, flood control), cultural services (recreational, aesthetic), and supporting services (nutrient cycling, soil formation). They are important because they contribute to human well-being and economic stability, highlighting the need for conservation and sustainable management of ecosystems.
