• Question 1 of 5 1. Question Consider the following statements. Climate change and unprecedented floods can facilitate the introduction of aquatic invasive alien species into new habitats. Invasive alien species slowly begin to wipe out local diversity and the economy by altering the functions of the ecosystem. Which of the above statements is/are incorrect? a) 1 only b) 2 only c) Both 1 and 2 d) Neither 1 nor 2 Correct Solution: d) Climate change and unprecedented floods resulting from cloud bursts have facilitated the introduction of aquatic invasive alien species into new habitats in India. This phenomenon threatens ecosystems, habitats and native species. Researchers say that during heavy floods, invasive alien fishes which are illegally farmed in fragile systems, including domestic aquarium tanks, ponds, lakes and abandoned quarries, effortlessly escape from captivity and enter nearby wetlands. After a while, they slowly begin to wipe out local diversity and the economy by altering the functions of the ecosystem.

• Question 2 of 5 2. Question Which of the following statements is correct regarding ‘Bamboonomics’? a) Encourage bamboo plantation by farmers in private lands. b) Promoting Bamboo as an alternative in building construction. c) Bamboo plantation in urban areas in order to maintain a sustainable environment and pollution free clean air. d) A movement to combat desertification and climate change Correct Solution: d) Bamboonomics: It is a movement to combat desertification and climate change which will involve the tribal community of India since they have the expertise in this field.

• Question 3 of 5 3. Question Consider the following statements regarding Ocean deoxygenation. Ocean deoxygenation is the maximum reduction of oxygen minimum zones in the world’s oceans as a consequence of anthropogenic emissions of carbon dioxide. Oxygen is less soluble in warmer water. The areas of Sea water that is depleted of dissolved oxygen is called Anoxic waters. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 1 is incorrect. Ocean deoxygenation is the expansion of oxygen minimum zones in the world’s oceans as a consequence of anthropogenic emissions of carbon dioxide. The change has been fairly rapid and poses a threat to fish and other types of marine life, as well as to people who depend on marine life for nutrition or livelihood. Ocean deoxygenation poses implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitats. Most of the excess heat from CO2 and other greenhouse gas emissions is absorbed by the oceans. Warmer oceans cause deoxygenation both because oxygen is less soluble in warmer water, and through temperature driven stratification of the ocean which inhibits the production of oxygen from photosynthesis. Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen and are a more severe condition of hypoxia. Incorrect Solution: b) Statement 1 is incorrect.

• Question 4 of 5 4. Question During winter the vehicles with closed doors and windows remain warmer than the temperature outside. This may be due to a) High pollution outside the vehicle b) Heat Conduction by metallic frame of vehicle c) Ionizing radiation effect d) Greenhouse effect Correct Solution: d) A greenhouse is made up of glass. The glass which is transparent to incoming short wave solar radiation is opaque to outgoing long wave radiation. The glass, therefore, allows in more radiation and prevents the long wave radiation going outside the glass house, causing the temperature inside the glasshouse structure warmer than outside. When you enter a car or a bus, during summers, where windows are closed, you feel more heat than outside. Likewise during winter the vehicles with closed doors and windows remain warmer than the temperature outside. Incorrect Solution: d) A greenhouse is made up of glass. The glass which is transparent to incoming short wave solar radiation is opaque to outgoing long wave radiation. The glass, therefore, allows in more radiation and prevents the long wave radiation going outside the glass house, causing the temperature inside the glasshouse structure warmer than outside.
