Environment & Biodiversity MCQs

Notes:
The Wildlife Institute of India is an autonomous institution under the Ministry of Environment Forest and Climate change, Government of India. It was established in 1982. It has a research facility that includes Remote Sensing and GIS, Laboratory, Forensics, etc.

Notes:
A seismograph which is also called as a seismometer, is an instrument which is used to detect and record the earthquake waves. The first seismograph was invented in 132 A.D.

Notes:
The Screening Criteria under Environment Impact Assessment are based upon the following:
1. Scales of investment
2. Type of development
3. Location of development

Notes:
Micro-organisms that can live within the pore interstices of sedimentary and even igneous rocks to depths of several kilometers are referred to as Lithophiles. Some of these mico-organisms are known to live on surface rocks, and make use of photosynthesis for energy.

Notes:
Montane Wet Temperate Forests is found in upper
reaches of North Bengal hills with an
altitude between 1650 m-3000 m. The main sites of these forests are Selimbong, Kankibong, Little Rangit,
Lopchu, Mahaldiram, Paglajhora, etc
in the districts of Darjeeling and
Kalimpong. The species commonly found in these forests are oak, maple,
pine, fir, deodar and spruce.

Notes:
Around the world, there is an increasing trend in areas of land, surface waters and groundwater affected by contamination because of one reason or other. However in the last three decades a special interest in the world has aroused by the potential of using the biological methods in the waste water treatment. Water hyacinth (Eichhornia crassipes) constitutes an important part of an aquatic ecosystem. Water hyacinth as a very promising plant with tremendous application in wastewater treatment is already proved. Water hyacinth is used to treat waste water from dairies, tanneries, sugar factories, pulp and paper industries, palm oil mills, distilleries, etc.

Notes:
Absence of fish along a river indicates zone of degradation. This zone is found for a certain length just below the point where sewage is discharged into the river-stream. This zone is characterised by water becoming dark and turbine with formation of sludge deposits at the bottom. D.O is reduced to about 40% of the saturated value.

Notes:
The Mudumalai National Park and Wildlife Sanctuary, now also declared a Tiger Reserve, lies on the northwestern side of the Nilgiri Hills, in Nilgiri District, about 150 km north-west of Coimbatore city in the westernmost part of Tamil Nadu, on the interstate boundaries with Karnataka and Kerala states in South India. The sanctuary is a haven for Bengal Tigers and Indian Leopards and other threatened species.

Notes:
The Gold Panda is the highest conservation award by the World Wide Fund for Nature (WWF), the leading global environmental organisation. WWF is an international non-governmental organization founded in 1961, working in the field of the wilderness preservation, and the reduction of humanity’s footprint on the environment.

Notes:
Vjetrenica Cave, positioned in Ravno, Bosnia and Herzegovina, boasts remarkable biodiversity. As the world’s most biodiverse grotto, it houses over 200 animal species, with 90 troglobionts, creatures that live specifically in caves. The gem of nature spans 7,014 meters, augmented by four rivers, lakes, and waterfalls. Named for the chilling winds emanating from its entrance, it maintains a constant 11 degrees Celsius temperature. Chronologically, its first mention was in 77 A.D by Pliny the Elder, and it has been a protected sanctuary since 1950. This haven for cave-dwelling animals also features unique species, including bacteria and fungi.
