  • Question 1
    1 / -0
    Which of the following is a result of habitat destruction, poaching, climate change and lack of resource management?
    Solution
    Habitat destruction, poaching, climate change and lack of resource management have resulted in a decline in biodiversity by leading to the extinction of species. Other factors such as large body size, small population, and position at a higher trophic level also favor extinction of species. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out.
    So, the correct answer is 'Decline in biodiversity'.
  • Question 2
    1 / -0
    Which of the following statements is correct?
    Solution
    In general, species diversity, in general, increases from poles to the equator. With very few exceptions, tropics (latitudinal range of 23.5° N to 23.5° S) harbor more species than temperate or polar areas. The reason is that tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to greater species diversity.
    So, the correct answer is 'Species diversity, in general, increases from poles to the equator'.
  • Question 3
    1 / -0
    Which statement is not true about biodiversity in India?
    Solution
    Indo-Burma is a biodiversity hotspot. Ecological hot spots are large areas of Earth's land surface which have high concentrations of plant endemism and also experience high rates of habitat loss. In India, 4 ecological hot spots are presently identified. The Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland constitute the 4 biodiversity hotspots in our country. One of the major features of these places is the presence of numerous endemic species.
    So, the correct answer is 'Indo-Burma is not a biodiversity hotspot'.
  • Question 4
    1 / -0
    Write the correct sequence of genetic diversity?
    Solution
    Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. The correct sequence is population, species, chromosomes, genes and then nucleotides from a higher to lower level. It becomes more specific from higher to lower level as the number of organisms keeps decreasing. It serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment.
    So, the correct answer is 'Population, Species, Chromosomes, Genes, Nucleotides'.
  • Question 5
    1 / -0
    Which one of the following is correct to measure 13-diversity?
  • Question 6
    1 / -0
    Which one of the following groups of species belongs to one family?
  • Question 7
    1 / -0
    Which one of the following was the objective of signing the ,Monyreal Protocal?
  • Question 8
    1 / -0
    Which of the following national parks is home to the famous deer Hangul?
    Solution
    Dachigam National Park is famous for Hangul and is located in Jammu and Kashmir. A park in use for conservation purposes is known as a National park. It is basically a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Flora and fauna are provided immense protection in such areas. Currently, in India, we have 166 national parks. 
    So, the correct answer is 'Dachigam National Park, J and K'.
  • Question 9
    1 / -0
    Which of the following is the most important cause of animals and plants being driven to extinction?
    Solution
    • When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. 

    • The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. 

    • Factors such as large body size, habitat loss, and fragmentation (a most important factor), small population and position at a higher trophic level favor extinction.

    So, the correct answer is 'Habitat loss and fragmentation'.
  • Question 10
    1 / -0
    Marine invertebrates are protected in 
    Solution
    Marine invertebrates include all animals with no backbone that live in the marine environment. There are six main groups of invertebrates: sponges, crustaceans, mollusks, echinoderms, tunicates, and coelenterates, among others. They are protected in the Gulf of Cambay. It is a bay on the Arabian Sea coast of India, bordering the state of Gujarat. It is about 200 km long, about 20 km wide in the north and up to 70 km wide in the south.
    So, the correct answer is 'Gulf of Cambay'.
