• Question 1 of 5 1. Question Consider the following statements regarding ex-situ conservation methods: Cryopreservation of gametes involves storing them at very high temperatures in an inert medium. Botanical gardens serve as a repository for rare and threatened plant species, conserving them outside their natural habitat. The establishment of seed banks is a method of in-situ conservation. Captive breeding programs in zoos often aim to reintroduce the offspring of endangered animals back into the wild. How many of the above statements are correct? a) Only one b) Only two (c) Only three (d) All four Correct Solution: B Statement 1 is incorrect. Cryopreservation is a technique used to preserve viable gametes (sperms and eggs), tissues, or embryos for long periods by storing them at very low temperatures (typically -196°C in liquid nitrogen), not high temperatures. This process halts all biological activity, allowing the genetic material to be preserved for future use in artificial insemination or IVF. Statement 2 is correct. Botanical gardens are a classic example of ex-situ conservation for plants. They cultivate and maintain collections of living plants, including many rare, threatened, and endemic species, outside their natural habitats. They play a crucial role in conservation, research, and public education. Statement 3 is incorrect. The establishment of seed banks, where seeds of different plant species are stored under controlled conditions (low temperature and humidity), is a method of ex-situ conservation, not in-situ. It preserves the genetic diversity of plants away from their natural environment, safeguarding them from threats like habitat loss and climate change. Statement 4 is correct. Modern zoos increasingly function as conservation centers. Captive breeding programs for endangered species are a key component of their work. The ultimate goal of many of these programs is not just to maintain a captive population but to breed individuals for reintroduction into their natural habitats, helping to augment or re-establish wild populations.

• Question 2 of 5 2. Question Consider the following statements regarding bioremediation: It is a universally applicable technique that can effectively treat all types of contaminants, including heavy metals like lead and mercury, by completely degrading them. Bioremediation processes are consistently faster and less expensive than conventional physical and chemical treatment methods for all polluted sites. In-situ bioremediation techniques function entirely on their own without the need for external amendments like oxygen or nutrients to enhance microbial activity. Which of the statements given above is/are correct? (a) 1 and 2 only (b) 3 only (c) 1, 2 and 3 (d) None Correct Solution: D Statement 1 is incorrect. Bioremediation is not universally applicable. While highly effective for organic contaminants (like petroleum hydrocarbons), its effectiveness with heavy metals is different. Microorganisms cannot “degrade” or destroy elemental heavy metals like lead and mercury. Instead, they can be used to immobilize or transform them into less toxic or less mobile forms through processes like biosorption or biotransformation, but the metals themselves persist in the environment. Statement 2 is incorrect. While bioremediation can be more cost-effective in the long run for certain types of contamination, it is often a much slower process than physical or chemical methods like incineration or chemical oxidation. The speed and cost-effectiveness are highly site-specific and contaminant-specific. For sites requiring rapid cleanup, chemical or physical methods are often preferred despite higher costs. Statement 3 is incorrect. While some natural attenuation occurs, most practical applications of in-situ bioremediation involve biostimulation, which is the process of adding amendments to the subsurface to stimulate the existing microorganisms. These amendments often include oxygen (through air sparging), electron acceptors, or nutrients (like nitrogen and phosphorus) that are limiting factors for microbial growth.

• Question 3 of 5 3. Question Consider the following statements regarding the Protected Area Network in India: The Wildlife Protection Act, 1972, prohibits any person from residing within the limits of a notified Sanctuary. The National Tiger Conservation Authority (NTCA) has the mandate to ensure that areas linking one tiger reserve with another are not diverted for ecologically unsustainable uses. A Community Reserve Management Committee is constituted by the local Gram Sabha without any representation from the State Forest Department. How many of the above statements are correct? a) Only one b) Only two c) All three d) None Correct Solution: A Statement 1 is incorrect. The Wildlife Protection Act, 1972, does not impose a blanket ban on residence within a Sanctuary. It allows certain persons to reside, including public servants on duty, persons who own immovable property within the sanctuary’s limits (whose rights have not been acquired by the government), and their dependents. The Chief Wildlife Warden can also grant permits for temporary residence for specific purposes like research or tourism. Statement 2 is correct. This is a specific and crucial mandate of the NTCA under Section 38-O(g) of the Wildlife (Protection) Act, 1972. The authority is tasked with ensuring that tiger reserves and critical corridor areas that link one protected area or tiger reserve with another are not diverted for ecologically unsustainable uses, except in the public interest and with the approval of the National Board for Wild Life. This provision is vital for maintaining landscape-level connectivity for tigers and other wildlife. Statement 3 is incorrect. The management of a Community Reserve is participatory, but it is not exclusive to the Gram Sabha. The Community Reserve Management Committee is constituted by the State Government and, as per the rules, includes representatives from the village Panchayat or Gram Sabha as well as representatives from the State Forest Department. This ensures a collaborative management approach, combining local knowledge with technical expertise from the forest department. Incorrect Solution: A Statement 1 is incorrect.

• Question 4 of 5 4. Question With reference to India’s legal framework, consider the following statements: The Biological Diversity Act, 2002, provides for the designation of ‘Biodiversity Heritage Sites’ for conservation purposes. The Environment (Protection) Act, 1986, is an ‘umbrella’ legislation that provides a framework for coordinating the activities of various central and state authorities. The Wildlife (Protection) Act, 1972, provides for the creation of National Parks and Wildlife Sanctuaries only. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Statement 1 is correct. Section 37 of the Biological Diversity Act, 2002, empowers state governments, in consultation with local bodies, to notify areas of biodiversity importance as Biodiversity Heritage Sites (BHS). These sites are unique, fragile ecosystems that can be terrestrial, coastal, inland water, or marine. Statement 2 is correct. The Environment (Protection) Act, 1986, was enacted in the wake of the Bhopal Gas Tragedy. It is often referred to as an ‘umbrella’ legislation because it fills gaps in earlier laws and provides the Central Government with broad powers to protect and improve the environment. It enables the establishment of authorities and the framing of rules (like the Rules of 1989 under which GEAC was formed) to coordinate environmental protection efforts across the country. Statement 3 is incorrect. The Wildlife (Protection) Act, 1972, provides for the creation of a network of Protected Areas. While National Parks and Wildlife Sanctuaries are the most well-known categories, the Act was later amended to include two other types of Protected Areas: Conservation Reserves and Community Reserves. These were added to provide flexible mechanisms for conservation in areas adjacent to existing protected areas or on private and community lands. Incorrect Solution: B Statement 1 is correct.
