Question 8

8,”The concept of carbon credit originated from which one of the following?”,2009,”(a) Earth Summit, Rio de Janeiro (b) Kyoto Protocol (c) Montreal Protocol (d) G-8 Summit, Heiligendamm”

Answer 8

8,b,The Kyoto Protocol invented the concept of carbon emissions trading, whereby carbon credits were a “flexibility mechanism”. Under this flexibility mechanism Annex 1 (developed countries) could use the carbon credits to meet their emission reduction commitments. A carbon credit is a generic term for any tradable certificate or permit representing the right to emit one tonne of carbon dioxide or the mass of another greenhouse gas with a carbon dioxide (tCO2 e) equivalent to one tonne of carbon dioxide.

Question 9

9,”Due to their extensive rice cultivation, some regions may be contributing to global warming. To what possible reason/reasons is this attributable ? 1.

In a Wildlife Sanctuary, limited biotic interference is permitted. Which of the statements given above is / correct ?”,2010,”(a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3”

Answer 12

12,c,The fix boundary of national park is described in Wild Life Protection Act, 1972 and the actual area of the national park is notified by state government. A biosphere reserve conserves an ecosystem and not just few specific species of plants and animals.

Question 13

13,”A pesticide which is a chlorinated hydrocarbon is sprayed on a food crop. The food chain is : Food crop – Rat – Snake – Hawk. In this food chain, the highest concentration of the pesticide would accumulate in which one of the following ?”,2010,”(a) Food crop (b) Rat (c) Snake (d) Hawk”

Answer 13

13,d,Biomagnification is the phenomenon of increasing concentration of compound in the tissue of organism, as the compound passes up a food chain, usually as a result of food intake. In this case, the concentration of compound will increase with increasing the tropic level. Biomagnifying pollutants which increases in concentration from producers → Primary consumers → Secondary consumers → Tertiary consumers → Top consumer. Hawk is the top consumer, so the pesticide concentration will be highest in Hawk.

Answer 16

16,a,Global warming is the increase in the average temperature of Earth’s near-surface air and oceans by increasing concentrations of greenhouse gases, which result from human activity such as the burning of fossil fuel and deforestation. Climate change mitigation is action to decrease the potential effects of global warming. At a time rate of mitigation is less in India because appropriate technologies are limited and costly. Moreover India don’t have huge funds required for research and development in that area.

Question 17

17,”Consider the following which can be found in the ambient atmosphere : 1. Soot 2. Sulphur hexafluoride 3. Water vapour Which of the above contribute to the warming up of the atmosphere?”,2010,”(a) 1 and 2 only (b) 3 only (c) 2 and 3 only (d) 1, 2 and 3”

Answer 17

17,d,Ambient temperature simply means “the temperature of the surroundings” and will be the same as room temperature. Indoors the common range is 20°C (68°F) to 27°C (80 °F). Similarly, ambient pressure on an object is the pressure of the surrounding medium, such as a gas or liquid, which comes into contact with the object. The soot, sulfur hexafluoride, and water vapor all three can be found at ambient atmosphere which corresponds to ambient temperature and pressure, and subsequently warming up of atmosphere.

(d) Carbon credits are traded at a price fixed from time to time by the United Nations Environment Programme.”

Answer 19

19,d,Under the Kyoto Protocol, the ‘caps’ or quotas for Greenhouse gases for the developed Annex 1 countries are known as Assigned Amounts and are listed in Annex B. The quantity of the initial assigned amount is denominated in individual units, called Assigned amount units (AAUs), each of which represents an allowance to emit one metric tonne of carbon dioxide equivalent, and these are entered into the country’s national registry.

Question 20

20,”Human activities in the recent past have caused the increased concentration of carbon dioxide in the atmosphere, but a lot of it does not remain in the lower atmosphere because of 1. its escape into the outer stratosphere. 2. the photosynthesis by phytoplankton in the oceans. 3. the trapping of air in the polar ice caps. Which of the statements given above is/are correct?”,2011,”(a) 1 and 2 (b) 2 only (c) 2 and 3 (d) 3 only”

Adaption of flora and fauna to warm and humid conditions Which three of the above are correct criteria in this context?”,2011,”(a) 1, 2 and 6 (b) 2, 4 and 6 (c) 1, 3 and 5 (d) 3, 4 and 6”

Answer 24

24,c,To qualify as a hotspot, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (> 0.5 percent of the world’s total) as endemics, and it has to have lost at least 70 percent of its original habitat. So we choose Species richness as well as Endemism. Along with this Threat perception is necessary to take, because it makes the base of this concept. Adaptation of flora is an arbitrary option, Ethno-botanical importance does nothing with the Biodiversity Hotspot selection criteria, vegetation Density is also discarded.

Question 25

25,”The Himalayan range is very rich in species diversity. Which one among the following is the most appropriate reason for this phenomenon ?”,2011,”(a) It has a high rainfall that supports luxuriant vegetative growth (b) It is a confluence of different bio-geographical zones.

Question 26

26,”There is a concern over the increase in harmful algal blooms in the seawaters of India. What could be the causative factors for this phenomenon? 1. Discharge of nutrients from the estuaries. 2. Run-off from the land during the monsoon. 3. Upwelling in the seas. Select the correct answer from the codes given below:”,2011,”(a) 1 only (b) 1 and 2 only (c) 2 and 3 only (d) 1, 2 and 3”

Answer 26

26,d,Algae multiply rapidly when nutrients are present. So, discharge of nutrients favors algae and subsequently algal bloom growth from estuaries to sea. The run off from the land during the monsoon brings salts which favor the growth of algae. Upwelling of the sea water brings the nutrients to top level leading to rapid algae multiplication.

Question 27

27,”Consider the following : 1. Photosynthesis 2. Respiration. 3. Decay of organic matter 4. Volcanic action. Which of the above add carbon dioxide to the carbon cycle on earth ?”,2011,”(a) 1 and 4 only (b) 2 and 3 only (c) 2, 3 and 4 only (d) 1 and 4”

Answer 27

27,c,Photosynthesis by plants removes about 120 billion tons of carbon from the air per year, but plant decomposition returns about the same amount. When the organic matter is oxidized through respiration, the reverse of photosynthesis takes place. Respiration releases CO2 into the atmosphere. Respiration and photosynthesis occur at nearly equal rates over one year. Volcanic eruptions and metamorphism release gases into the atmosphere. Volcanic gases are primarily water vapor, carbon dioxide and sulfur dioxide.

Question 28

28,”A sandy and saline area is the natural habitat of an Indian animal species. The animal has no predators in that area but its existence is threatened due to the destruction of its habitat. Which one of the following could be that animal ?”,2011,”(a) Indian wild buffalo (b) Indian wild ass (c) Indian wild boar (d) Indian gazelle”

Answer 28

28,b,The Indian wild ass are also called as ghudkhur in local Gujarati language, is a subspecies of the onager native of South Asia. It is unknown how they disappeared though they have never been hunting target during any emperors in India. The history speaks that their number has been declining after due to diseases such as surra and horse sickness. The process related to salt activities have also been a reason behind it.

114,a,”These camels can swim up to three kilometers into the sea in search of mangroves - So, 1 and 2 are correct. Most families in Jatt and Rabari communities of Kachchh, are traditional rearers of Kharai camels. So, the third statement is also correct. Kharai camels found in the Kutch region are very unique. They can swim through deep sea waters and feed on mangroves and other saline plants. The breeders have meticulously followed the traditional grazing pattern in the coastal districts. They do not provide special housing or shelter to the camels. Given the breed’s ability to survive both on land and sea, the Kharai camel is one of the most preferred choices of graziers in the arid coastal region of Kachchh. People consume its milk, while male calves are sold for economic returns (females are not sold because they are considered sacred). A male calf fetches anywhere between Rs. 6,000 and Rs.14,000, says Ramesh Bhatti of Sahjeevan, an NGO working on livelihood issues of graziers in Kachchh. It can be domesticated also – so it’s not wild. They are reared in four blocks of Abdasa, Bundra, Lakhpat and Bachau of Gujarat. Ref: DOWN TO EARTH (An important source for Env) Rare Kharai camel species, found in Kutch district, is under threat due to the onslaught of industrialisation, post-2001 earthquake.”

Answer 124

124,c,”Statement 1 is right (by common knowledge), but for the sake of reference- NCERT Class 12 biology page 30! This eliminates ‘B’. The second statement should be wrong because of the extreme word ‘drastic’. This eliminates ‘D’. Besides, I’m unable to find any specific reference that mentions the linkage between butterfly population vs. fungus infection. Birds and spiders tend to prey on butterflies (by common knowledge), so statement 3 is a possible outcome. Hence, the answer is ‘C’: 1 and 3 only.”

Question 125

125,”Biological Oxygen Demand (BOD) is a standard criterion for”,2017-I,”(a) Measuring oxygen levels in blood (b) Computing oxygen levels in forest ecosystems (c) Pollution assay in aquatic ecosystems (d) Assessing oxygen levels in high altitude regions”

Answer 125

125,c,”NCERT Class 11 Chemistry: Ch. 14-Environmental Chemistry, page 407. The amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water is called Biochemical Oxygen Demand (BOD). The amount of BOD in the water is a measure of the amount of organic material in the water, in terms of how much oxygen will be required to break it down biologically. Clean water would have a BOD value of less than 5 ppm, whereas highly polluted water could have a BOD value of 17 ppm or more.”

Question 126

126,”In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique?”,2017-I,”1. It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature. 2. Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using micro-organisms. 3. Genetic engineering can be used to create microorganisms specifically designed for bioremediation. Select the correct answer using the code given below: (a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3”

Answer 126

126,c,”Biosparging is an in-situ Bioremediation technique in which we inject the air under pressure below the water table to enhance the rate of biological degradation of contaminants by naturally occurring bacteria. Hence statement 1 is right. In Google Scholar search engine, it is filled with academic papers on genetic engineering approaches to bioremediation. Hence 3 is also right. But not all compounds are susceptible to rapid and complete biodegradation, and bioremediation often takes a longer time than other treatment processes. So the second statement is unlikely to be correct. Hence, the answer is ‘C’ 1 and 3 only.”

Question 127

127,”In the context of mitigating the impending global warming due to anthropogenic emissions of carbon dioxide, which of the following can be the potential sites for carbon sequestration?”,2017-I,”1.

Answer 134

134,b,”Central Pollution Control Board (CPCB) is a statutory organization constituted in September 1974 under the Water (Prevention and Control of Pollution) Act, 1974. So #1 is wrong. Principal functions of the CPCB, as spelt out in the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, (i) to promote cleanliness of streams and wells in different areas. So the last part of sentence #2 is right. Environment: National Green Tribunal (NGT) was set up in 2010 under the NGT Act, 2010, for the purpose of effective and expeditious disposal of cases relating to environmental protection. The Tribunal shall not be bound by the procedure laid down under the Code of Civil Procedure, 1908, but shall be guided by principles of natural justice. The Tribunal is mandated to make an endeavor for disposal of applications or appeals finally within 6 months of filing. So the first part of sentence #2 is right.”
