Under Environmental Studies (EVS) teaching, with reference to the methods of 'Biodiversity Conservation', consider the following differences between 'In-situ' and 'Ex-situ' conservation:
- 1. Under 'In-situ' conservation, endangered plant and animal species are conserved within their natural habitats, major examples of which include National Parks, Wildlife Sanctuaries, Biosphere Reserves, and Sacred Groves.
- 2. Under 'Ex-situ' conservation, organisms and flora are brought out of their natural habitats and kept in specially conserved artificial environments, which include Botanical Gardens, Zoos, Gene Banks, Cryopreservation, and Seed Banks.
- 3. 'Safari Parks' and 'Arboretums' are considered the best examples of 'In-situ' conservation because in these, wildlife is left completely free in their original natural forests without any human interference.
Which of the statement(s) given above is/are correct?
✓ Correct! Well done.
✗ Not quite — the correct answer is highlighted above.
Detailed Explanation
Statement 1 is correct because 'In-situ' conservation is the method in which species are conserved within their natural habitats (such as national parks, sanctuaries, biosphere reserves, etc.). Statement 2 is correct because in 'Ex-situ' conservation, organisms and plants are removed from their natural habitats and conserved in artificial or controlled environments such as zoos, botanical gardens, gene banks, or cryopreservation techniques. Statement 3 is incorrect because 'Safari Parks' and 'Arboretums' are examples of 'Ex-situ' conservation, not in-situ, because here organisms are kept outside their natural habitat in a man-made or managed enclosure. Thus, only statements 1 and 2 are correct.

With reference to EVS teaching and biodiversity conservation, consider the following statements regarding 'In-situ' and 'Ex-situ' conservation strategies: 1. Under 'In-situ' conservation, flora and fauna are conserved within their natural habitats, prominent examples of which are National Parks, Wildlife Sanctuaries, Biosphere Reserves, and Sacred Groves. 2. Under 'Ex-situ' conservation, endangered species are conserved outside their natural habitats in artificial or human-made special environments, prominent examples of which are Zoos, Botanical Gardens, Seed Banks, and Cryopreservation. 3. 'Corbett National Park' and 'Kaziranga National Park' established by the Government of India are considered the best and primary examples of Ex-situ conservation because wild animals are removed from their natural environment and kept in secure enclosures here.

With reference to various genetic disorders and infectious diseases occurring in the human body, consider the following statements: 1. 'Down Syndrome' is a chromosomal disorder caused by Trisomy of the 21st chromosome (Trisomy 21), which causes mental retardation, hindered physical growth, and specific physical features in the affected person. 2. 'Phenylketonuria' is an autosomal recessive genetic disorder in which phenylalanine cannot be converted into tyrosine due to a deficiency of the 'phenylalanine hydroxylase' enzyme in the body, causing mental disability. 3. With reference to anemia, 'Sickle Cell Anemia' is a sex-linked dominant genetic disease in which red blood cells become sickle-shaped due to the substitution of valine for glutamic acid in the beta-globin chain of hemoglobin.

Consider the following statements regarding 'Biodiversity and Conservation' in the teaching-learning of Environmental Studies (EVS): 1. Under 'In-situ Conservation', flora and fauna are conserved within their natural habitats, with prominent examples being National Parks, Wildlife Sanctuaries, and Biosphere Reserves. 2. Under 'Ex-situ Conservation', endangered species are brought out of their natural habitats and kept in specially protected environments, such as Botanical Gardens, Zoos, and Gene Banks. 3. The concept of 'Biodiversity Hotspots' was propounded by Norman Myers, and the minimum criteria for declaring an area a hotspot are that the region must contain at least 1,500 species of endemic plants and must have lost at least 75% of its primary native vegetation.
