Environment & Biodiversity MCQs

Notes:
The Adichunchanagiri Wildlife Sanctuary (AWLS) is located in Nagamangala Taluk of Mandya district of Karnataka and is spread over 0.88 square kilometres. This was created mainly for the conservation of peacocks. It also houses nearly 250 species of birds.

Notes:
The lion-tailed macaque or the wanderoo, is an Old World monkey endemic to the Western Ghats of South India. The lion-tailed macaque ranks among the rarest and most threatened primates. Their range has become increasingly isolated and fragmented by the spread of agriculture and tea, coffee, teak and cinchona, construction of water reservoirs for irrigation and power generation, and human settlements to support such activities.

Notes:
The Darrah National Park, which is now Mukundara Hills National Park, is located in within the Kathiawar-Gir dry deciduous forests’ ecoregion of Rajasthan and covers an area of 250 square kilometres. It is home to a number of species including the wild boar, deer, nilgai, cheetah and wolves. The park consists of three wildlife sanctuaries: Darrah Wildlife Sanctuary, Chambal Wildlife Sanctuary and Jawahar Sagar Wildlife Sanctuary. The River Chandrabhaga flows very close to the national park and there are a number of ancient temples, dating back to the 7th and 8th centuries that are situated along the banks of the river.

Notes:
The state of Madhya Pradesh has the maximum numbers of national parks. MP has six Tiger Reserves i.e. Kanha, Pench, Satpura, Bandhavgarh, Panna and Sanjay. Madhya Pradesh is followed by Kerala, Maharashtra and Uttarakhand and West Bengal. MP is planning to add 11 more protected areas.

Notes:
The Intergovernmental Panel which is an intergovernmental body of the United Nations, was founded in the year 1988 by Bert Bolin. Its head quarter is located in Geneva, Switzerland. Its objective is to provide scientific information that is relevant to understanding the scientific basis of the risk associated with climate change and its natural, political, economic impacts and possible remedies.

Notes:
The International Radon Project (IRP) is a research initiative that was launched in the 1980s by the World Health Organization (WHO) in order to study the health effects of radon exposure and to develop guidelines for the protection of human health from radon-induced radiation. Radon is a naturally occurring radioactive gas that is produced by the decay of uranium and radium, which are found in small amounts in soil, rock, and water. When radon is released into the air, it can be inhaled into the lungs, where it can expose the body to ionizing radiation and increase the risk of lung cancer.

Notes:
PM10 is particulate matter with 10 mm or less in diameter and PM2.5 is particulate matter with 2.5 micrometers or less in diameter. These particles are formed by burning fuel and chemical reactions that take place in the atmosphere which results environment pollution. A new study showed that PM2.5 is more harmful than PM10.

Notes:
Shale gas is natural gas that is found in shale formations. It has become a significant source of natural gas. It is becoming more and more popular in today’s Global Gas Exploration Market, because of its abundance.

Notes:
10 Biogeographic zones are Trans Himalayan zone, Himalayan zone, Desert zone, Semiarid zone, Western ghat zone, Deccan plateau zone, Gangetic plain zone, North east zone, Coastal zone and Islands present near the shore line

Notes:
In a Grassland, the number of producers i.e. plants and grasses is more than the herbivore and number of carnivores is more than the herbivores. The same is valid for Ponds. In Forests, the Pyramid of Number is a broad shaped. The producers are more, herbivores are less but carnivores are again more. In Parasitic food chain, the Pyramid of Numbers is always inverted
