Environment & Biodiversity MCQs

Notes:
The Pulie Badze Wildlife Sanctuary (PWS) is located at Kohima District of Nagaland and covers an area of 923 hectares.The sanctuary is a natural habitat for Blyth’s Tragopan (or Grey-bellied Tragopan).

Notes:
The Jaldapara National Park (JNP) is located at the foothills of the Eastern Himalayas in Alipurduar District of northern West Bengal and on the banks of the Torsa River. It is home to Indian leopard, Indian elephants, sambar, barking deer, spotted deer, hog deer, wild boars, gaur, etc. Jaldapara is a paradise for bird watchers. It is one of the very few places in India, where the Bengal florican is sighted. The other birds to be found here are the crested eagle, Pallas’s fish eagle, shikra, Finn’s weaver, jungle fowl, peafowl (peacock), partridge, and lesser pied hornbill. Pythons, monitor lizards, kraits, cobras, geckos, and about eight species of fresh water turtles can also be found here.

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:

Notes:
Earth Hour is organized by the WorldWildlife Fund (WWF).

WWF is mission is to stop the degradation of the Earth’s natural environment and build a future where people live in harmony with nature.

Notes:
Thermal pollution, the release of liquid or gas that increases heat in a surrounding area, has far-reaching and damaging ecological effects by impacting aquatic organisms and animal populations. Cold-blooded organisms adapted to specific temperature ranges. If water temperatures change too much, metabolic processes break down. Unlike humans, who can adapt to wide temperature ranges, most organisms live in narrow temperature niches. Unlike humans, who can adapt to wide temperature ranges, most organisms live in narrow temperature niches and their metabolism breaks down at higher temperatures.

Notes:
At high altitudes, there is less oxygen available. This makes the air thinner and drier. The climate inside your nose also gets drier because of this. This makes the blood vessels exposed inside your nose more likely to burst there than at lower altitudes.

Notes:

Sedimentary cycle refers to that cycle in which nutrients does not flow through atmosphere but follows a pattern i.e through erosion, sedimentation, mountain building and through the biological transportation. Phosphorous occurs in large amount in rocks unlike nitrogen and carbon dioxide which is obtained through atmosphere.

Notes:

Xerophytic vegetation is found in desert area with high temperature, low rainfall. The trees are cactus, having short leaves, deep roots and grow in sandy soil. The trees are scattered in this vegetation.

Notes:
Heliophytes are sun loving plants. These are those that require full exposure to sun for their development. Example- mullein, ling, thyme and soft velcro, white clover, and most roses
