FAQs on Terrestrial Ecosytems Video Lecture - Famous Books for UPSC Exam (Summary & Tests)

1. What are terrestrial ecosystems?
Ans. Terrestrial ecosystems refer to the ecosystems that exist on land, including forests, grasslands, deserts, and tundra. These ecosystems are characterized by the presence of a variety of plants, animals, and microorganisms that interact with each other and with the physical environment.
2. How do terrestrial ecosystems support life?
Ans. Terrestrial ecosystems support life by providing habitat and resources for a wide range of organisms. They play a crucial role in the carbon cycle by absorbing carbon dioxide through photosynthesis, which helps regulate the Earth's climate. Additionally, these ecosystems supply food, water, and shelter to both plant and animal species, contributing to biodiversity and ecosystem stability.
3. What are the major threats to terrestrial ecosystems?
Ans. Terrestrial ecosystems face several threats, including deforestation, habitat loss, pollution, climate change, and invasive species. Deforestation, for example, leads to the loss of forest ecosystems and their biodiversity. Pollution from industrial activities and agriculture can degrade soil and water quality, harming the organisms that rely on these resources. Climate change, caused by human activities, poses a significant threat to terrestrial ecosystems by altering temperature and precipitation patterns. Invasive species can outcompete native species, disrupting the balance of the ecosystem.
4. How can we conserve terrestrial ecosystems?
Ans. Conserving terrestrial ecosystems requires a combination of measures. One important step is protecting natural habitats through the establishment of national parks, reserves, and protected areas. Sustainable land management practices, such as reforestation, afforestation, and implementing sustainable agriculture techniques, can help restore and maintain ecosystem health. Additionally, reducing greenhouse gas emissions and adopting sustainable practices in various sectors, such as energy, transportation, and industry, can mitigate the impacts of climate change on terrestrial ecosystems.
5. What is the role of biodiversity in terrestrial ecosystems?
Ans. Biodiversity plays a crucial role in terrestrial ecosystems. It refers to the variety of life forms, including plants, animals, and microorganisms, and the ecological roles they play. Biodiversity contributes to the stability and resilience of ecosystems, as different species have unique functions and interactions within the ecosystem. A diverse range of species ensures that ecological processes, such as nutrient cycling and pollination, occur efficiently. Additionally, biodiversity can provide ecosystem services, such as water purification, soil formation, and pest control, which are vital for human well-being.
