Environment & Biodiversity MCQs

Notes:
The Keoladeo National Park (KNP) is located in the Bharatpur district of Rajasthan. It is home to Nilgai, feral cattle, chital deer, wild boar, Indian porcupine, etc. The park is famous avifauna sanctuary that hosts thousands of birds, especially during the winter season. The reserve protects Bharatpur from frequent floods, provides grazing grounds for village cattle, and earlier was primarily used as a waterfowl hunting ground.

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 Environment (Protection) Act of India was enacted in 1986 with the objective of providing for the protection and improvement of the environment. The act was enacted by Parliament of India under Article 253 of the Indian Constitution. The act empowers the Central Government to establish authorities with the mandate of preventing environmental pollution in all its forms.

Notes:
The Buxa Tiger Reserve (BTR) is located inside the Buxa National Park in Alipurduar district of West Bengal and covers an area of 760-square-kilometre. It is home to tiger, civet, elephant, gaur (Indian bison), Indian boar, red jungle fowl, etc. The Endangered species found in the reserve are Indian tiger, Asian elephant, leopard cat, Bengal florican, regal python, Chinese pangolin, hispid hare, etc.

Notes:
Eutrophication is when a body of water becomes overly enriched with minerals and nutrients which impetus to excessive growth of algae. It causes oxygen depletion of the water body. Due to this problem algal bloom occurs which is the increase of phytoplankton.

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:
Methane gas is produced by the decomposition of organic waste in an oxygen-free environment. The treatment and handling of waste water also produces Methane.

Notes:
This feedback loop, known as the ‘ice-albedo feedback’, amplifies the initial warming caused by rising levels of greenhouse gases. Detecting, understanding and accurately quantifying climate feedbacks have been the focus of a great deal of research by scientists unraveling the complexities of Earth’s climate.

Notes:
Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky. It is generally used to denote visibility-reducing aerosols of the wet type.
