46. Which of the following agricultural practices have been primarily responsible for pollution of our water resources?
A. Use of live-stock manure
B. Use of chemical fertilisers
C. Excessive use of chemical pesticides
D. Deforestation
[A] B and C
[B] A, C and D
[C] A and B
[D] A, B and D
Show Answer
Correct Answer: A [B and C]
Notes:
Use of chemical fertilisers and excessive use of chemical pesticides are primarily responsible for pollution of our water and land resources. Manure and pesticides contains nutrients, such as phosphorus and nitrogen, and pathogens, including bacteria, viruses and parasites. These pollutants contaminate water resources and reduce recreational potential of lakes and rivers, destroy wildlife habitat, and eliminate drinking water supplies for people and livestock.
47. Environmental pollution can be controlled by _____:
[A] Sewage treatment
[B] Manufacturing electric vehicles
[C] Checking atomic blasts
[D] All of the above
Show Answer
Correct Answer: D [All of the above ]
Notes:
Checking atomic blasts will reduce radioactive pollution. Sewage pollution can be prevented by treating sewage before passing into water course, in sewage treatment plant or effluent treatment plant (ETP). Electrically operated vehicles will control automobile exhaust and improve the air quality in cities. Environmental pollution can be controlled by treating factory wastes before disposing of them. So, if we treat wastewater before disposing of in a river, it will surely decrease the amount of dumped pollutants. For example- Steel industries have a high concentration of cyanide in it, and it led to harmful effect. So, treatment is really necessary.
48. Green House Effect means _____:
[A] Cultivation of crops in green house to conserve heat
[B] Trapping of solar energy due to carbon dioxide gases
[C] Trapping of solar energy by earth upper surface
[D] Increase of heat due to atmospheric pollution
Show Answer
Correct Answer: B [Trapping of solar energy due to carbon dioxide gases]
Notes:
Green House Effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric green house gases and is re-radiated in all directions. It results an increase in average temp of the planet.
49. Solar energy is converted into chemical energy during ____:
[A] Photosynthesis
[B] Combustion
[C] Transition
[D] Fusion
Show Answer
Correct Answer: A [Photosynthesis]
Notes:
Photosynthesis in plants converts radiant energy from the sun into chemical energy in the form of glucose (sugar) using electrons and protons from water. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Water (6H2O) + Carbon Dioxide (6CO2) + Sunlight (Radiant Energy) = Glucose (C6H12O6) + Oxygen (6O2).
