  • Question 1
    1 / -0

    In ex-situ conservation, the animals or plants are conserved in everything except?

    Solution

    Biosphere reserves are the part of in-situ conservation i.e. conservation of genetic resources through their maintenance in natural or man-made ecosystems in which they occur.

  • Question 2
    1 / -0

    What is common between Khasi hills, Jaintia hills and Aravalli hills?

    a. They are biodiversity hotspots.
    b. They are sacred groves.
    c. They are areas of ex-situ conservation.

    Solution

    Khasi, Jaintia and Aravali hills are biodiversity hotspots as well as sacred groves.
    Bio-diversity hotspots are used for in-situ conservation. As Khasi, Jaintia and Aravali hills are biodiversity hotspots, they are areas of in-situ conservation, and not ex-situ conservation.

  • Question 3
    1 / -0

    Exploring molecular genetics and species level diversity for products of economic importance is termed as?

    Solution

    Bioprospecting is exploring molecular genetics and species level diversity for products of economic importance. It is the systematic search for and development of new sources of chemical compounds, genes, micro-organisms and other valuable products from nature.

  • Question 4
    1 / -0

    Which is the most probable reason for the extinction of the passenger pigeon?

    Solution

    Passenger pigeons became extinct due to overexploitation. The passenger pigeons' migration and nesting behavior made them easy to hunt in large numbers, thus overhunting made them extinct.

  • Question 5
    1 / -0

    The 'evil quartet' does not include?

    Solution

    Evil quartet does not mention climatic change and global warming as a cause of extinction.
    The devil or evil quartet is a sobriquet used to describe the four major causes that have led to the accelerated rate of extinction of species.

  • Question 6
    1 / -0

    Which of the following features may a genetically diversified plant possess?

    a. Different concentration of the active chemical.
    b. Same concentration of the active chemical.
    c. Different active compounds.
    d. Different potency of the same active chemical.

    Solution

    Genetically diversified plants might show the difference in terms of concentration and potency of the active chemical.

  • Question 7
    1 / -0

    In which group of vertebrates is maximum global biodiversity found?

    Solution

    Maximum global biodiversity is found in fishes. There are about 30,000 species of fishes discovered so far.
    Birds with 9,956 species rank second in biodiversity.
    Reptiles with 8,240 ranks 3rd in global biodiversity.
    Amphibians with 6,199 species ranks 4th in global biodiversity.

  • Question 8
    1 / -0

    Which characteristics should a stable community possess?

    a. No variability in productivity from year to year.
    b. Resistance to occasional disturbance.
    c. High adaptability to alien species.

    Solution

    A stable community should not show much variation in productivity from year to year. It should also be resistant to occasional disturbances which are either natural or man-made.

  • Question 9
    1 / -0

    What happens to species diversity as we move from equator to pole?

    Solution

    Species diversity decreases as we move away from the equator towards the poles because temperature decreases and conditions become harsh.

  • Question 10
    1 / -0

    Which of the following animals is an odd one out?

    Solution

    Giant Panda is an endangered species.If not taken care of, it can become extinct in a few years. All others are extinct species.
