Environment & Biodiversity MCQs

Notes:
The Ghats traverse the States of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat.
According to the new report by the International Union for Conservation of Nature (IUCN) namely “IUCN World Heritage Outlook 3”, India’s Western Ghats are threatened by population pressure, urbanization and climate change. The site is regarded as of significant concern.

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:
Kewra or keya bushes are also the most common vegetation
of these forests, which grow in clumps
or group. Kewra is widely utilized as a plantation species to create a shelter belt along the coastal areas and offshore islands of Bangladesh.

Notes:
An Air Quality Index (AQI) of 301-500 is considered as hazardous to human health. It denotes the severely polluted state of air. AQI values over 300 trigger health warnings of emergency conditions. The entire population is even more likely to be affected by serious health effects.

Notes:
Lichens are used as air pollution indicators, especially of the concentration of Sulphur dioxide in the atmosphere. If air is very badly polluted with sulphur dioxide there may be no lichens present, just green algae may be found. If the air is clean, shrubby, hairy and leafy lichens become abundant.

Notes:
Biotic components are the living things that shape an ecosystem. Examples of biotic components include animals, plants, fungi, and bacteria. Abiotic components are non-living components that influence an ecosystem. Examples of abiotic factors are temperature, air currents, and minerals.

Notes:
The greenhouse effect is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a temperature above what it would be without its atmosphere. It caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air.

Notes:
Sultanpur National Park is located at Sultanpur, Haryana in Gurgaon District, Haryana. As a bird sanctuary it was the finding of Peter Jackson, famous ornothologist, and Honorary Secretary of the Delhi Birdwatching Society, who wrote to Prime Minister of India, Indira Gandhi, founder of the Society, in 1970 about the need to declare the Sultanpur jheel near Delhi, a bird sanctuary, and she asked him to take her there.

Notes:
Garampani Wildlife Sanctuary is located in Karbi Anglong district, Assam. It is located at 92 km from Diphu. It is one of the oldest sanctuaries containing hot water spring and waterfalls and surrounded by Nambor Sanctuary having 51 rare species of orchid.

Notes:
The Gondwana Rainforests, designated as a World Heritage Site, are located in southeast Queensland and northeast New South Wales in Australia. They personify extraordinary instances of Earth’s evolutionary phases, with over 50 sheltered areas playing host to more than 200 rare or endangered species. These rainforests are remnants from the ancient supercontinent Gondwana, evident through tree lineages such as Red and Yellow Carabeen. Unfortunately, they are threatened by climate change and provide important habitats for scarce species like the Hastings River Mouse and Parma Wallaby. Drawing around 2 million tourists each year, these vast rainforests cover an impressive 366,500 hectares.
