Weekly Quiz Competition
  • Question 1
    1 / -0
    Which of the following is an ex situ method of conservation?
    Solution
    • The method of preservation of components of biological diversity outside their natural habitats is called ex situ conservation. 
    • Cryopreservation is the method of preservation of structurally intact living cells and tissues at very low temperature.
    • The agroforestry, sanctuary, and biosphere reserve are the methods of in situ conservation.
    Thus, the correct answer is option C. 
  • Question 2
    1 / -0
    Which one of the following is not used for ex situ plant conservation?
    Solution
    Shifting cultivation results into deforestation. Botanical gardens have a collection of living plants for reference. Seed banks store seeds as a source of germplasm, in case seed reserves elsewhere are destroyed. Field genebanks are a type of biorepository which preserves the genetic material.

    So, the correct answer is 'Shifting cultivation'.
  • Question 3
    1 / -0
    Given below are a few statements related to biodiversity. Pick those that correctly describe the concept of biodiversity.
    (i) Biodiversity refers to the different species of flora and fauna present in an area.
    (ii) Biodiversity refers to only the flora of a given area.
    (iii) Biodiversity is greater in a forest.
    (iv) Biodiversity refers to the total number of individuals of a particular species living in an area.
    Solution
    Biodiversity refers to the different species of flora and fauna present in an area. The forest has a wide variety of flora and fauna which flourishes widely in the given area and are a rich source of biodiversity. Biodiversity is not concerned with a particular species .
    So, the correct answer is option C.
  • Question 4
    1 / -0
    Number of wild life is continuously decreasing.What is the main reason of this : -
    Solution
    Wildlife refers to all living organisms (terrestrial, aquatic and aerial) living in all possible natural habitats of their own, other than the cultivated plants and domesticated animals. Thus 'wildlife' does not exist only in jungles and are hunted down but wildlife includes even the migrating birds, turtles, coral reefs, microorganisms, insects, fishes, etc. Several hundred organisms are endangered or on the verge of extinction. The reasons are deforestation, pollution, killing, overexploitation etc. The most important among them is deforestation or destruction of their natural habitat because it will affect the species (flora and fauna) of the complete area and not only a few organisms. The natural habitat may be destroyed by man for his settlements, grazing grounds, agriculture, mining, industries, dam building, etc. As a consequence of this, the species must adapt to the changes, move elsewhere or may succumb to predation, starvation or disease, and eventually dies.

    So, the correct answer is 'Destruction of habitat'.
  • Question 5
    1 / -0
    Which one of the following has maximum genetic diversity in India ?
    Solution
    answer:
    Correct Answer: C
    Explanation:
    • Out of the 12 megadiversity found and listed in the world, India is one of them.
    • It also has maximum number of genetic diversity in the world.
    • In India, Rice has the maximum varieties of strains which is around 50,000.
    • Second maximum variety is of Mango which is 1000.
    Hence, the maximum genetic diversity in India is of Mango.
  • Question 6
    1 / -0
    One of the most important functions of botanical gardens is that -
    Solution
    So the correct option is A.

  • Question 7
    1 / -0
    Sacred groves are specially useful in
    Solution
    • Sacred Groves are the ideal centre for biodiversity conservation. Various plants and animals that are threatened in the forest are well conserved within these patches. 
    • These areas also provide habitat, water and nest-sites for many species of wildlife and birds. 
    • Ayurvedic and general medicinal plants that are not to be found in the forest are often concentrated in sacred groves. 
    • Religious belief and taboos are the constructive tools for conserving the sacred groves. 
    • Rare, endangered, threatened and endemic species are abundant in sacred groves. 

    So, the correct answer is 'Conserving rare and threatened species'
  • Question 8
    1 / -0
    One of the ex-situ conservation methods for endangered species is -
  • Question 9
    1 / -0
    Which one of the following expanded forms of the following acronyms is correct?
    Solution
    IUCN, International Union for Conservation of Nature, helps the world find pragmatic solutions to our most pressing environment and development challenges. IUCN work focuses on valuing and conserving nature, ensuring effective and equitable governance of its use, and deploying nature-based solutions to global challenges in climate, food and development. Thus, option A is correct.
    IPCC stands for Intergovernmental Panel on Climate Change. Thus, option B is wrong.
    UNEP stands for United Nations Environment Programme. Thus, option C is wrong.
    EPA stands for Environmental Protection Agency. Thus, option D is wrong.
  • Question 10
    1 / -0
    The study of total number and types of organisms present on earth is _______.
    Solution
    • Biodiversity is the term used to describe the variety of life found on Earth and all of the natural processes. This can refer to genetic variation, ecosystem variation, or species variation within an area, biome, or planet. The biodiversity is more concentrated within tropical ecosystems than temperate ecosystems. 
    • Ecology is the study of the relationships between living organisms, including humans, and their physical environment.
    • Taxonomy is the science of naming, describing, and classifying organisms and includes all plants, animals, and microorganisms of the world.
    • The ordering of organisms into groups based on similarities and differences is called classification.
    So, the correct answer is option C.
