  • Question 1
    1 / -0
    Conservation of organisms in natural habitat is called as
    Solution
    When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected, for example we save the entire forest to save the tiger. 
    This approach is called as in-situ (on site) conservation. 
    However, when there are situations where an animal or plant is endangered or threatened and needs urgent measures to save it from extinction, ex-situ (off site) conservation is the desirable approach.
  • Question 2

    Flamingos reproduce in
    Solution

    Chilika lake is the largest wintering ground for migratory birds, on the Indian subcontinent. It is one of the hotspots of  biodiversity in the country. Some species listed in the IUCN red list of threatened animals inhabit the lake for at least part of their life cycle like white bellied sea eagles, greylag geese, purple moorhen, jacana, herons and flamingos. Large flocks of greater flamingos from Iran and the Rann of Kutch in Gujarat, feed in the shallow waters of the lake.

    Therefore, the correct answer is option A.

  • Question 3
    1 / -0
    The venue and year of the Earth summit on conservation of biodiversity was
    Solution
    First world Earth summit was held at Rio de Janeiro in 1992, in Brazil. It promoted 'Convention on Biological Diversity' (CBD), which was signed by 152 nations. The various commitments were - 
    (i) Adoption of ways and means to conserve biodiversity. 
    (ii) Managing biodiversity for sustainable use.
    (iii) Ensuring equitable sharing of benefits from biological diversity, including utilisation of genetic resources.
  • Question 4
    1 / -0
    Nowadays, rhino is present in
    Solution
    Rhinoceros often abbreviated as rhino, is a group of five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to Southern Asia. In India 'Project Rhino' for conservation of rhino was launched in the year 1987 and rhinos are protected in 'Kaziranga National Park' in Jorhat, Assam, Manas Sanctuary, Barpeta in Assam, and Jaldapara sanctuary in Modhirat, Bengal.
  • Question 5
    1 / -0
    Which of the following bird has gained importance as wild life in recent years?
    Solution
    The great Indian bustard (Ardeotis nigriceps) or Indian bustard is a bird found in India and the adjoining regions of Pakistan. 
    A large bird with a horizontal body and long bare legs giving it an ostrich like appearance, this bird is among the heaviest of the flying birds. This bird is endangered and is hence protected. It is state bird of Rajasthan. It has been protected in 'Desert National Park' near Jaisalmer. It is found in coastal grasslands of the Abdasa and Mandvi talukas of Kutch District of Gujarat. 
  • Question 6
    1 / -0
    At present, the lions (Panthera leo) are found only in
    Solution
    The lion (Panthera leo) is one of the five big cats in the genus Panthera and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia (where an endangered remnant population resides in 'Gir Forest National Park', Gujarat, India), while other types of lions have disappeared from North Africa and Southwest Asia in historic times. 
  • Question 7
    1 / -0
    Which of the following represents the biodiversity of an area?
    Solution
    In our biosphere immense diversity (or heterogeneity), exists not only at the species level but at all levels of biological organisation ranging from macromolecules within cells to biomes. Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organisation. The most important of them are- 
    (i) Genetic diversity.
    (ii) Species diversity.
    (iii) Ecological diversity.
  • Question 8
    1 / -0
    Species going to be extinct due to low reproductive rate is
    Solution
    The two reasons which can contribute to the extinction of the species are environmental changes and characteristics of the organism. The characteristics of the organism may involve the reproductive rate of the species. The giant panda has a low reproductive rate. When there is a low reproductive rate, less number of organisms are produced in one gestation phase. There are fewer members to mate and reproduce. This will result in the extinction of the species. 
    Thus, the correct answer is option C. 
  • Question 9
    1 / -0
    Hippopotamus is found in
    Solution

    Solution
    'The World Wide Fund for Nature' (WWF) is an international non governmental organization founded on April 29, 1961, and is working on issues regarding the conservation, research and restoration of the environment. 
    WWF's giant panda logo originated from a panda named 'Chi Chi', that had been transferred from Beijing zoo to London zoo in 1958, three years before WWF became established.
