Environment & Biodiversity MCQs

Notes:
The Grizzled Squirrel Wildlife Sanctuary (GSWS) is located in Virudhunagar and Madurai districts of Tamil Nadu and covers an area 485.2 sq Kms. Over 240+ species of birds are seen in this sanctuary including 14 species of birds endemic to the Western Ghats, such as the critically endangered Oriental white-backed vulture and the long-billed vulture. In addition to grizzled giant squirrels, the sanctuary is home to numerous animals such as barking deer, bonnet macaque, common langur, elephants, flying squirrels, gaur, Indian giant squirrel, leopard, lion-tailed macaques, mouse deer, Nilgiri langur and Nilgiri Tahrs. There are over 220 species of butterflies including many rare and endemic species. Some of the rare butterflies spotted here include Eversheds ace , Silver royal , Orange awlet , Hampsons hedge blue , etc.

Notes:
Aanaimalai Tiger Reserve was also known as Indira Gandhi Wildlife Sanctuary and National Park is located in the state of Tamil Nadu. The practice of sliding timber logs down the hills from a place located in the northeast corner of the park is named as “Topslip”. It is a famous tourist attraction.

Notes:
The Chhilchhila Wildlife Sanctuary is located in the Indian state of Haryana. In 1986, it was declared as a bird sanctuary. The Oriental darter and the painted stork have been identified near endangered in the sanctuary.

Notes:
Namdhapa National Park is the largest National park in North East India. It is located in the state of Arunachal Pradesh. It is India’s third largest National Park. It is home to the common Indian leopard, snow leopard, clouded leopard and tiger.

Notes:
Black soil is known for its ability to hold moisture. This soil can retain moisture for a long time, which can help crops during dry seasons. Black soil is sticky when wet, so it’s difficult to work with. It’s usually tilled after the first shower or during the pre-monsoon period.
The ability of soil to retain water is related to the size of its particles. Clay soil has small, fine particles, so it retains the most water. Sand has larger particles and retains the least water. Silt and loam have medium-size particles and retain a moderate amount of water.

Notes:
The correct answer is Energy. In a food chain, the transfer of energy is characteristically inefficient – a phenomenon known as the 10% rule, implying that only around 10% of the energy at each trophic level is available for transfer to the next. This invariably leads to a decrease in energy across each level of the food chain. Incidentally, due to this inefficiency of energy transfer, the length of food chains is often restricted, and extensive systems for recycling nutrients and materials exist in ecosystems.

Notes:
The Montreal Protocol on Substances that Deplete the Ozone Layer was an international treaty which was organized in 1987. The UN General Assembly celebrate 16th September in memory of the date in 1987 when nations inked the Montreal Protocol.
