  • Question 1
    1 / -0
    Which of the following shows the maximum diversity?
  • Question 2
    1 / -0
    World biodiversity day is
    Solution
    'World Biodiversity Day' also known as the 'International Day for Biological Diversity', was created in 1993 by the United Nations as an international day for the promotion of biodiversity issues.  
    For its first 7 years, it was celebrated on 29 December as the day that the 'Convention on Biological Diversity' (CBD) went into effect. In 2000, the date was changed to May 22$$^{nd}$$, to mark the day that the convention was adopted at the Rio 'Earth Summit' in 1992.
  • Question 3
    1 / -0
    Which one of the following is an example of in-situ conservation?
    Solution
    Sacred groves are the fine example of in-situ conservation. Sacred groves are forest fragments, size varying between 0.5 - 500 hectare, which are protected by religious communities and have a significant religious connotation for the protecting community. Sacred groves are the mini forests with rich diversity. Around 15,000 sacred groves have been reported from different parts of India. 
  • Question 4
    1 / -0
    Four species of birds have different egg colours: [1] white with no markings, [2] pale brown with no markings, [3] grey-brown with dark streaks and spots, [4] pale blue with dark blue-green spots. Based on egg colour, which species is most likely to nest in a deep tree hole?
    Solution
    White birds with no markings would likely to nest in a deep tree hole as they can't camouflage with the surroundings and can easily be prey for its predators. Others can hide themselves under the color of trees. 
    Therefore, the correct answer is option A.
  • Question 5
    1 / -0
    Gene bank is collection of
    Solution
    Gene bank is the repositories where biological material is collected, stored, and made available for the future purpose. The main role of plant gene banks is to preserve genetic diversity, in the form of seeds or cuttings in the case of plants reproduced vegetatively and subsequently make this material, together with associated information, available for future use in research and plant breeding. A seed bank preserves dried seeds by storing them at a very low temperature. Spores and pteridophytes are conserved in seed banks. In tissue bank, buds, protocorm and meristematic cells are conserved through particular light and temperature arrangements in a nutrient medium. This technique is used to preserve seedless plants and plants which reproduce asexually. Pollen bank is a method in which pollen grains are stored. Field gene bank is a method of planting plants for the conservation of genes.
    Therefore, the correct answer is option D.
  • Question 6
    1 / -0
    An in situ method of conservation is
    Solution
    In-situ conservation is on site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators. In India following types of natural habitats are being maintained: 
    1. National parks, 
    2. Wildlife sanctuaries, 
    3. Biosphere reserves.
    Therefore, the correct answer is option B.
  • Question 7
    1 / -0
    Kaziranga National Park is located in the state of
    Solution
    Kaziranga National Park is a national park in the Golaghat and Nagaon districts of the state of Assam, India. As a world heritage site, the park hosts two-thirds of the world's great one-horned rhinoceroses
    So, the correct answer is 'Assam'
  • Question 8
    1 / -0
    When plant diversity is maintained in natural habitat the conservation is called?
    Solution
    When animals are conserved in their natural habitats, it is called in situ conservation. When animals are preserved apart from their natural habitats, in other areas, like sanctuaries and natural parks, it is called ex-situ conservation. 
    In vitro studies are the ones that are done in test tubes outside human or animal bodies. In vivo means procedures performed in living organisms.
    So, the correct answer is option D. 
  • Question 9
    1 / -0
    Which one of the following is not a conservation category of wildlife?
    Solution
    Vulnerable species are those that have been categorized by the International Union for Conservation of Nature as likely to become endangered unless the conditions harming their survival and reproduction are improved.
    Endangered species are those that are at the risk of extinction.
    Endemic species are those that exist only in one particular geographic region.
    Thus the correct answer is option C.
  • Question 10
    1 / -0
    The Siberian crane from Russia is a regular visitor to the bird sanctuary in which place in India? 
    Solution
    The Keoladeo National Park formerly known as the Bharatpur Bird Sanctuary in Bharatpur, Rajasthan, India is a famous avifauna sanctuary that plays host to thousands of birds especially during the winter season. The rare Siberian cranes migrate during winter in this park.
    Therefore, the correct answer is option D.
