B Correct answer
Explanation

CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals.

So, the correct option is 'CITES = Convention in International Trade in Elite Species.'

Select the correct term for the following definitions (i, ii, iii, iv).
(i) The taxon is liable to become extinct if not allowed to realise its full biotic potential by providing protection from exotic species/human exploitation/ habitat deterioration/ depletion of food.
(ii) The taxon has been completely eliminated or died out from earth, e.g., Dodo.
(iii) The taxon is facing a high risk of extinction in the wild in the near future due to decrease in its habitat, excessive predation or poaching.
(iv) They are species with naturally small populations, either localised or thinly scattered, which are always at risk from pests/pathogens/predators/exotic species.

  1. (i) - Threatened; (ii) - Extinct; (iii) - Endangered; (iv) - Rare

  2. (i) - Endangered; (ii) - Extinct; (iii) - Threatened; (iv) - Rare

  3. (i) - Extinct; (ii) - Rare; (iii) - Threatened; (iv) - Endangered

  4. (i) - Threatened; (ii) - Extinct; (iii) - Rare; (iv) - Endangered
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

(i) A threatened species is a plant, animal, or other living organism that is becoming rare and that may become in danger of extinction if current trends continue. The international Union for the Conservation of Nature (IUCN) divides threatened species into three categories: vulnerable species, endangered species and critically endangered species. The US National Wildlife federation on the other hand, distinguishes between threatened and endangered species.

(ii) Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world - the species has died out. This is a natural part of evolution. But sometimes extinctions happen at a much faster rate than usual.
(iii) An endangered species is a species which has been categorized as very likely to become extinct. Endangered (EN), as categorized by the International Union for Conservation of Nature (IUCN) Red List, is the second most severe conservation status for wild populations in the IUCN's schema after Critically Endangered (CR). Many nations have laws that protect conservation-reliant species: for example, forbidding hunting, restricting land development or creating preserves. Population numbers, trends and species' conservation status can be found at the lists of organisms by population.
(iv) A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term endangered or threatened. Designation of a rare species may be made by an official body, such as a national government, state, or province. The term more commonly appears without reference to specific criteria. The IUCN does not normally make such designations, but may use the term in scientific discussion. Rarity rests on a specific species being represented by a small number of organisms worldwide, usually fewer than 10,000. However, a species having a very narrow endemic range or fragmented habitat also influences the concept. Almost 75% of known species can be classified as "rare'.
So the correct option is '(i)- threatened, (ii)- extinct, (iii)- endangered, (iv)- rare'.

  4. (i) - Rajasthan; (ii) - Meghalaya; (iii) - Karanataka and Maharashtra
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

(i) In Meghalaya sacred groves represent a long tradition of environmental conservation based on indigenous knowledge by the tribal communities. They are among the few least disturbed forest patches which are serving as the natural treasure house of biodiversity and a refuge for a large number of endemic, endangered and rare taxa. The general term for sacred groves in the Khasi Hills is 'Khlaw Kyntang' or 'Law Kyntang' or 'Law Lyngdoh' while in the Jaintia Hills it is called 'Khloo Blai'. The sacred groves in the Khasi Hills and Jaintia Hills District are fundamentally based on the traditional religious belief of the tribals i.e., Khasis and Pnars, which is called Seng Khasi and Niam Tre respectively.

(ii) Sacred Groves are found from the western part of Rajasthan to the east of the Aravalli range. These groves are known under various names in Rajasthan as sacred groves (deora, malvan, deorai, rakhat bani, oran, etc.), sacred corridors (deo ghats), temple forests (mandir van) and sacred gardens (baugh). Brandis, as early as 1887, gave initial information on sacred groves of Aravallis. He wrote, 'though very few papers have been published on sacred groves, this does not mean that such areas do not abound in India'. 
(iii) Western Ghats also known as Sahyadri (Benevolent Mountains) is a mountain range that runs parallel to the western coast of the Indian peninsula. Forest clearance was inevitable for farming and yet, there was an overwhelming belief in the sacredness of the woods.  They were important tracts of pre-colonial forest conservation in the Western Ghats. Myriad relics of such groves, exist even today all over the Western Ghats. They may be called Devrai in Maharashtra, Devarkadu in Kodagu and Kavu in Kerala and Tamil Nadu, these forests in pre-colonial landscape, served many functions like the conservation of biodiversity and watershed, moderation of climate and promoted varied wildlife.
So the correct option is ' (i) Meghalaya, (ii) Rajasthan (iii) Karnataka and Maharashtra'.

  3. Quarterly event

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The correct answer is 'annual event'

Migration done by birds is usually dome during winters in search of a warmer environment and food. Since winters are only one of the 4 seasons of a year, migration only occurs during winters and thus only once a year.
