FAQs on Biodiversity And Conservation MCQs With Answers For Exam Preparation
1. What is biodiversity in biology?
Biodiversity is the variety and variability of living organisms at the genetic, species, and ecosystem levels. It includes all forms of life on Earth, from microorganisms to plants and animals.
- Genetic diversity: Variation of genes within a species.
- Species diversity: Variety of different species in a region.
- Ecosystem diversity: Variety of habitats, communities, and ecological processes.
2. What are the three levels of biodiversity?
The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity. These levels describe variation at different biological scales.
- Genetic diversity: Differences in DNA among individuals of the same species.
- Species diversity: Number and abundance of species in a community.
- Ecosystem diversity: Variety of ecosystems such as forests, deserts, and wetlands.
3. Why is biodiversity important for ecosystem stability?
Biodiversity is important for ecosystem stability because it increases resilience against environmental changes and disturbances. A diverse ecosystem can better withstand diseases, climate change, and natural disasters.
- Ensures stable food chains and food webs.
- Improves nutrient cycling and soil fertility.
- Enhances resistance to invasive species.
4. What are biodiversity hotspots?
Biodiversity hotspots are regions with exceptionally high species richness and a high level of endemic species that are under serious threat. These areas are priority zones for conservation efforts.
- Contain at least 1,500 endemic vascular plant species.
- Have lost at least 70% of original habitat.
- Examples include the Western Ghats and Madagascar.
5. What is conservation of biodiversity?
Conservation of biodiversity is the protection, preservation, and management of species, habitats, and ecosystems to prevent extinction. It aims to maintain ecological balance and ensure sustainable use of natural resources.
- Protects endangered and threatened species.
- Maintains genetic diversity.
- Prevents habitat destruction.
6. What is the difference between in situ and ex situ conservation?
The difference between in situ conservation and ex situ conservation lies in where species are protected. In situ conservation protects species in their natural habitats, while ex situ conservation protects them outside their natural habitats.
- In situ: National parks, wildlife sanctuaries, biosphere reserves.
- Ex situ: Zoos, botanical gardens, seed banks, gene banks.
7. What are the main causes of biodiversity loss?
The main causes of biodiversity loss are habitat destruction, overexploitation, invasive species, pollution, and climate change. These factors reduce species populations and disrupt ecosystems.
- Habitat loss: Deforestation and urbanization.
- Overexploitation: Overfishing and hunting.
- Invasive species: Non-native species outcompeting native species.
- Climate change: Altered temperature and rainfall patterns.
8. What is an endangered species?
An endangered species is a species that is at a very high risk of extinction in the near future. Its population size has declined significantly due to environmental or human-related factors.
- Small population size.
- Restricted geographic distribution.
- Rapid population decline.
9. What is the role of national parks in biodiversity conservation?
National parks play a crucial role in biodiversity conservation by protecting entire ecosystems in their natural state. They restrict human activities like hunting, logging, and industrial development.
- Preserve natural habitats.
- Protect endangered species.
- Maintain ecological processes.
10. What is the importance of genetic diversity in conservation?
Genetic diversity is important in conservation because it allows species to adapt to environmental changes and resist diseases. Low genetic variation increases the risk of extinction.
- Enhances adaptability to climate change.
- Improves disease resistance.
- Reduces effects of inbreeding.
