Solutions:

Ans 1 (d):

The Ministry of Environment, Forest & Climate Change has notified the revised standards for coal-based Thermal Power Plants in the country, with the primary aim of minimising pollution. These standards are proposed to be implemented in a phased manner. Thermal power plants are categorised into 3 categories, namely those:- (i) Installed before 31st December, 2003 (ii) Installed after 2003 upto 31st December, 2016 and (iii) Installed after 31st December, 2016. The new standards are aimed at reducing emission of PM10(0.98 kg/MWh), sulphur dioxide(7.3 Kg/MWh) and Oxide of nitrogen (4.8 kg/MWh), which will in turn help in bringing about an improvement in the Ambient Air Quality (AAQ) in and around thermal power plants. The technology employed for the control of the proposed limit of Sulfur Dioxide – SO2 & Nitrogen Oxide – NOx will also help in control of mercury emission (at about 70-90%) as a co-benefit.

Ans 2 (c):

In Ex situ Conservation approach, threatened animals and plants are taken out from their natural habitat and placed in special setting where they can be protected and given special care. Zoological parks, botanical gardens and wildlife safari parks serve this purpose.

Ans 3 (a):

Ground level ozone is formed through a complex reaction between involving hydrocarbons, nitrogen oxides, and sunlight.

Ans 4 (c):

Ans 5 (a):

Ans 6 (b):

Under Section 37 of Biological Diversity Act, 2002 (BDA) the State Government in consultation with local bodies may notify in the official gazette, areas of biodiversity importance as Biodiversity Heritage Sites (BHS). Under sub section (2) of Section 37, the State Government in consultation with the Central Government may frame rules for the management and conservation of BHS. Under sub section (3) of Section 37, the State Governments shall frame schemes for compensating or rehabilitating any person or section of people economically affected by such notification.
