  • Question 1
    1 / -0
    Ten species (i) to (x) sampled in four areas  $$A-D$$ having $$11-13$$ habitats (given in brackets) possess populations (in thousands) given in the table. Which one has the maximum species diversity
    (i)(ii)(iii)(iv)(v)(vi)(vii)(viii)(ix)(x)
    A(11)2.31.20.526.0-3.11.19.0-10.3

    D(12)3.210.211.14.80.43.30.87.311.32.1
    Solution
    A) The given region does not have much species richness. 
    B) The given region has the least species richness. 
    C) The region has the second largest (sum total) of species richness. 
    D) The region has the most species richness (by adding up the columns). 
    So the correct answer is 'D'. 
  • Question 2
    1 / -0
    Which one of the following is an example of ex situ conversation
    Solution
    Ex situ conservation is the conservation of selected rare plants or animals in places outside the natural forms.
    Ex-situ conservation includes off-site collection and gene banks. Ex situ conservation is conserving the animals and plant outside the natural habitat. 
    Ex situ conservation includes offsite collection and gene banks.
    Offsite collections are the live collection of file and domesticated species in the botanical garden.
    Gene bank is an institution where available plant material is preserved in a viable condition.
    Seed Bank stores seed in the viable state
    Zoos or zoological parks are places where animals are kept in captivity and bred.
    So, the correct option is 'Seed bank'
  • Question 3

    • They are nocturnal animals and have hairy feet that protect the fox from the hot desert sand.
  • Question 4
    1 / -0

  • Question 5
    1 / -0
    Which of the following is not an ex-situ conservation?
    Solution
    In situ conservation is the production and management of important components of biological diversity through a network of protected areas. This can be wildlife sanctuaries, national parks, biosphere reserves etc.

    Ex situ conservation is the conservation of selected rare plants or animals in places outside the natural forms.
    Ex-situ conservation includes off-site collection and gene banks. Ex situ conservation is conserving the animals and plant outside the natural habitat. 
    Ex situ conservation includes offsite collection and gene banks.
    Offsite collections are the live collection of file and domesticated species in the botanical garden.
    Gene bank is an institution where available plant material is preserved in a viable condition.
    Seed Bank stores seed in the viable state
    Zoos or zoological parks are places where animals are kept in captivity and bred.
    So, the correct option is 'Biosphere reserve'
