(A) Kalpakkam (Tamil Nadu)
(B) Narora (Uttar Pradesh)
(C) Chernobyl (Ukraine)
(D) Trombay (Maharashtra)
Q.65. The term biodiversity was coined by
(A) R.F. Dasmann
(B) Arnies Naess
(C) FE. Clements
(D) Norman Myers
The term biological diversity was used first by Raymond F. Dasmann, a wildlife scientist and conservationist. He used the term in a book published in 1968 titled “A Different Kind of Country”
Later the term biodiversity short form of biological diversity, is coined by W.G. Rosen in 1985 while planning the 1986 National Forum on Biological Diversity organized by the National Research Council (NRC).
Q.66. The term Smog was coined by
(A) M.S. Swaminathan
(B) C.C. Park
(C) Dr. H.A. Des Veaux
(D) Norman Myers
Harold Des Veaux coined the word smog in 1905
Q.67. Green Muffler is
(A) A method of forestation
(B) A technology for reducing air pollution
(C) Plantation along roadside to reduce noise pollution
(D) A method of reducing soil pollution
Green Muffler is a technique of reducing noise pollution by planting 4-6 rows around the populated areas or noisy places like along roadsides, industrial areas, societies near highways, etc. so that dense trees reduce noise pollution as they filter out the noise and obstruct it reaching the citizens. A muffler (silencer in British English) is a device for decreasing the amount of noise emitted by the exhaust of an internal combustion engine.
Q.68. Bhopal Gas disaster occurred in the year
(A) 13 December, 1980
(B) 3 December, 1982
(C) 3 December, 1984
(D) 23 December 1986
The Bhopal disaster, also referred to as the Bhopal gas tragedy, was a gas leak incident on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. It is considered among the world’s worst industrial disasters. Over 500,000 people were exposed to methyl isocyanate (MIC) gas.
Q.69. In Delhi, maximum noise pollution in day time is due to
(B) Vehicular Traffic
(C) Radio and TV
(D) Kitchen Appliances

|A. Earth Summit/Rio Summit (1992)||1. For the protection and Maintenance of ozone layer|
|B. Montreal Protocol (Canada, 1987)||2. For the reduction in the Erosion of carbon dioxide|
|C. Kyoto Protocol (Japan, 1997)||3. Focus on Climate Change, Global Warming, Forest Protection Biodiversity and Agenda 21|
|D. Vienna Convention (Austria, 1985)||4. Protection of Atmospheric Ozone layer from C.F.Cs|
|E. Toronto Summit (Canada, 1998)||5. Reduction of the emission of CO, By the developed countries|
- Earth Summit/Rio Summit (1992) – Focus on Climate Change, Global Warming, Forest Protection Biodiversity and Agenda 21
- Montreal Protocol (Canada, 1987) – Protection of Atmospheric Ozone layer from C.F.Cs
- Kyoto Protocol (Japan, 1997) – For the reduction in the Erosion of carbon dioxide
- Vienna Convention (Austria, 1985) – For the protection and Maintenance of ozone layer
- Toronto Summit (Canada, 1998) – Reduction of the emission of CO, By the developed countries
Q.71. Which one of the following is the most important factor responsible for decline of biodiversity?
(A) Genetic Assimilation
(B) Destruction of Habitat
(C) Air Pollution
(D) Controlling Predator
Destruction of habitat is the most important factor responsible for decline in biodiversity. The disbalance in biodiversity taking place is just because of habitat fragmentation which results in loss of endangered animal and plant species.
Q.72. A plant adapted to a wet environment is called
- Hydrophytes – are aquatic plants that are especially suited for living in aquatic environments. Example: Lotus, Sea weeds, Pistia, Water lily etc.
- Xerophytes- are plant that has adaptations to survive in an environment with little liquid water, such as a hot or cold desert.
- Phreatophytes- is a deep-rooted plant that obtains water that it needs from the phreatic zone i.e zone of saturation or the capillary fringe above the phreatic zone.
- Mesophytes- a plant need only a moderate amount of water. as they are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments.
- Trophophytes -are the plants acts as mesophyte during rainy season and xerophyte during dry season.
Q.73. Plants that grow under high intensity of disturbance and low intensity of stress are called as –
(B) Stress Tolerators
(C) Coniferous Forests
A ruderal species is a plant species that is first to colonize disturbed lands. The disturbance may be natural – for example, wildfires or avalanches – or a consequence of human activity, such as construction or agriculture. The word ruderal comes from the Latin rudus, meaning “rubble”.
Q.74. Which of the following is consider to be the Global Carbon Sink
(A) Antarctic Ice Sheet
(B) Equatorial Rainforest
(C) Sahara Desert
(D) Arctic Ocean
Q.75. The Ecological Niche refers to
(A) Interaction between man and environment
(B) Interdependence of man and plant
(C) The functional role of an organism in the ecosystem
(D) Relationship of biotic and abiotic Components
The term ecological niche was developed by Charles Elton.
Ecological niche may be defined as ‘the functional role and position (micro-habitat) of species in its ecosystem, including what resources it uses, how and when it uses the resources, and how it interacts with other species.
