  • Question 1
    1 / -0
    Migratory birds fly to far away areas during a particular time of the year. Which of the following conditions present in their habitat during that time are responsible for this behaviour?
    (i) Unavailability of food
    (ii) Extreme weather conditions
    (iii) Over-crowding
    (iv) Lack of nesting areas
    Solution
    • The dwelling of a species in a particular area depends on the physical, biological, and climatic conditions. 
    • The adverse conditions, because of any climatic variations or scarcity of food forces the birds to migrate to faraway areas in search of better living conditions. 
    • The migration of the species may lead to a decrease in the biodiversity of that region.

    So, the correct answer is option D.
  • Question 2
    1 / -0
    Plants which are restricted to a particular area in their distribution are referred to as
    Solution
    • Endemic species are likely to develop on biologically isolated areas such as islands, because of their geographical isolation. 
    • Endemic plants are special because they are found exclusively in a particular area. They are not naturally found anywhere else.
    • This makes them both incredibly special and more vulnerable to extinction. 
    • As we only found them in certain locations, they require special conservation efforts.

    So the correct answer is option D.
  • Question 3
    1 / -0
    Which of the following records are maintained by the 'Red Data Book'? 
    (i) Endemic species
    (ii) Flowering plants
    (iii) Endangered plants
    (iv) Endangered animals
    Solution
    • Red Data Book is a catalogue (a complete list) that is published by the International Union for Conservation of Nature (IUCN). 
    • The Red Data Book keeps a record of all the endangered plants and endangered animals.
    • So, the correct answer is option 'C'. 
  • Question 4
    1 / -0
    Extensive plating of trees to increase forest cover is called :
    Solution
    Extensive plating of trees to increase forest cover is called afforestation.
    Option "A" is correct.
  • Question 5
    1 / -0
    Students were taken to a museum on an educational trip. Which one of the following documents will provide the information on endangered animals and plants?
    Solution
    A red data book contains lists of species whose continued existence is threatened. Species are classified into different categories of perceived risk. Each red data book usually deals with a specific group of animals or plants. They are now being published in many different countries and provide useful information on the threat status of the species
    So, the correct answer is 'Red data book'
  • Question 6
    1 / -0

    The endemic fauna includes chinkara, nilgai, barking deer, cheetah, leopards, wild dogs, the Indian wolf, Bison, Indian giant squirrels and flying squirrels.
    Thus, the correct answer is option A.
  • Question 7
    1 / -0
    Biodiversity can be conserved by developing:
    Solution
    Biodiversity can be conserved by developing biosphere reserves and national park.
    A biosphere reserve can be defined as a protected land or area to conserve the biological and cultural diversity of a region while promoting sustainable economic development. 
    A national park is an area reserved for wildlife where they can freely use the habitat and natural resources. 
    Thus, the correct answer is option D.
  • Question 8
    1 / -0
