6 Questions
What is the definition of biodiversity?
Biodiversity is defined as the variety of all animals, plants, microorganisms, and the ecological complexity they interact with, including non-living factors like soil, air, and light.
What are the main threats to biodiversity and causes of extinction?
Threats to biodiversity and cases of extinction are caused by habitat destruction, fragmentation, environmental pollution, soil erosion, agricultural expansion, urbanization, deforestation, and indiscriminate hunting.
How can the introduction of exotic species lead to the extinction of wild animals?
Exotic species introduction can lead to the extinction of wild animals by causing dominant species to eliminate existing species in the area.
How can disturbances in migratory routes lead to the extinction of animals?
Disturbances in migratory roots, such as building dams along fish migration routes, can block their path and lead to extinction.
How can lack of education about wildlife and its importance lead to the loss of biodiversity?
Lack of education about wildlife and its importance can lead to people not understanding the significance of conserving wildlife and ecosystems.
What are the two main approaches to the conservation of biodiversity?
Conservation of biodiversity can be done through Insitu conservation (protecting wildlife in their natural habitat) and Exsitu conservation (protecting wildlife in man-made environments).
Study Notes
- Biodiversity is defined as the variety of all animals, plants, microorganisms, and the ecological complexity they interact with, including non-living factors like soil, air, and light.
- Threats to biodiversity and cases of extinction are caused by habitat destruction, fragmentation, environmental pollution, soil erosion, agricultural expansion, urbanization, deforestation, and indiscriminate hunting.
- Exotic species introduction can lead to the extinction of wild animals by causing dominant species to eliminate existing species in the area.
- Disturbances in migratory roots, such as building dams along fish migration routes, can block their path and lead to extinction.
- Lack of education about wildlife and its importance can lead to people not understanding the significance of conserving wildlife and ecosystems.
- Conservation of biodiversity can be done through Insitu conservation (protecting wildlife in their natural habitat) and Exsitu conservation (protecting wildlife in man-made environments).
- Insitu conservation includes Sacred forests, Sacred lakes, Biosphere reserves, National parks, and Wildlife sanctuaries that protect wildlife based on specific activities allowed in different zones.
- India has 18 Biosphere reserves, 106 National parks, and 567 Wildlife sanctuaries.
- Biosphere reserves are specific areas divided into three zones: Core Zone (no human activities allowed), Buffer Zone (limited human activities allowed), and Manipulative Zone (multiple human activities allowed).
- Exsitu conservation involves activities like Botanical gardens, Zoos, Gene banks, Tissue culture, Pollen culture, DNA banks, Cryo-preservation to protect wildlife in man-made environments.
- Cryo-preservation involves storing DNA or tissue samples in liquid nitrogen at -196 degrees Celsius to prevent any fungal, viral, or bacterial activity.
Test your knowledge on biodiversity conservation, threats, and strategies to protect wildlife and ecosystems. Learn about the importance of biodiversity, habitat destruction, exotic species introduction, conservation methods such as Insitu and Exsitu conservation, and the role of Biosphere reserves, National parks, and Wildlife sanctuaries.
