Question 1 of 5
1. Question
1 pointsConsider the following statements regarding Eco-sensitive zones.
1. Eco-Sensitive Zones (ESZs) are areas notified by the Ministry of Environment, Forests and Climate Change (MoEFCC) around Protected Areas, National Parks and Wildlife Sanctuaries.
2. They act as a transition zone from areas of high protection to areas involving lesser protection.
3. Eco-Sensitive Zones are defined and mentioned in Environment (Protection) Act, 1986.
Which of the above statements is/ are correct?Correct
Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the Ministry of Environment, Forests and Climate Change (MoEFCC), Government of India around Protected Areas, National Parks and Wildlife Sanctuaries. The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas. They also act as a transition zone from areas of high protection to areas involving lesser protection.
ESZ are regulated by central government through Min. of Environment, Forests and Climate change (MoEFCC).
Ministry came out with new guidelines for regulation of such areas in 2011. The Environment Protection Act, 1986 does not mention the word “Eco-sensitive Zones”.Incorrect

Question 3 of 5
3. Question
1 pointsConsider the following statements about Photosynthetically Active Radiation (PAR).
1. Photosynthetically Active Radiation (PAR) is the amount of light available for photosynthesis.
2. PAR changes seasonally and varies depending on the latitude and time of day.
3. Higher PAR leads to decrease in plant growth.
4. Air pollution does have an effect on PAR.
Which of the above statements is/are correct?Correct
Photosynthetically Active Radiation (PAR) is the amount of light available for photosynthesis, which is light in the 400 to 700 nanometer wavelength range. PAR changes seasonally and varies depending on the latitude and time of day.
Levels are greatest during the summer at mid-day. Air pollution also affects PAR by filtering out the amount of sunlight that can reach plants.
Photosynthetically Active Radiation is needed for photosynthesis and plant growth. Higher PAR promotes plant growth.Incorrect
