FAQs on Functions of an Ecosystem Video Lecture - Famous Books for UPSC Exam (Summary & Tests)

1. What is an ecosystem?
Ans. An ecosystem refers to a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their non-living environment. It includes both the biological and physical components of a specific area, such as a forest, desert, or ocean.
2. How do ecosystems function?
Ans. Ecosystems function through various processes, including energy flow and nutrient cycling. Energy flows through the ecosystem as it is transferred from one organism to another through food chains and food webs. Nutrient cycling involves the recycling of essential elements, such as carbon, nitrogen, and phosphorus, within the ecosystem through processes like decomposition and nutrient absorption by plants.
3. What are the primary producers in an ecosystem?
Ans. Primary producers, also known as autotrophs, are organisms that convert sunlight energy into chemical energy through photosynthesis. They are typically plants, algae, and some bacteria. These producers form the base of the food chain by providing energy-rich organic compounds that are consumed by other organisms.
4. How do ecosystems support biodiversity?
Ans. Ecosystems support biodiversity by providing various habitats and niches for a wide range of species. Each ecosystem has unique conditions and resources that allow different organisms to thrive. The interactions between different species within an ecosystem, such as predator-prey relationships and symbiotic associations, contribute to the overall diversity of life forms.
5. What are the key services provided by ecosystems?
Ans. Ecosystems provide a wide range of services, including the provision of food, clean water, air purification, climate regulation, and cultural and recreational values. They also play a crucial role in maintaining the overall health and stability of the planet by regulating natural processes, such as the carbon cycle and water cycle.
