Q382. Identify the incorrect statement regarding the Snow Leopard.
Explanation
The snow leopard is famously known as the "Ghost of the Mountains" due to its elusive nature and serves as an indicator of high-altitude ecosystem health. Its diet primarily consists of wild sheep and goats. Uniquely, unlike other big cats like lions or tigers, the snow leopard lacks the laryngeal morphology required to roar, making the claim of frequent roaring scientifically incorrect.

Q383. The presence of a healthy population of Gangetic dolphins in a river segment indicates:
Explanation
The Gangetic dolphin is considered an apex predator in the riverine food web. Its presence in a river segment is a reliable indicator of a healthy freshwater ecosystem. Because these dolphins require clean water and an abundant supply of fish to survive, a thriving population suggests low pollution levels and high biodiversity in that particular stretch of the river system.

Q384. Read the following statements and select the correct option: Statement I: Snow Leopards are threatened primarily by retaliatory killing by herders, poaching, and climate change. Statement II: The Global Snow Leopard and Ecosystem Protection Program (GSLEP) is an intergovernmental alliance of range countries.
Explanation
Snow leopards face severe threats from poaching, climate change, and retaliatory killing by herders whose livestock are preyed upon. To address these challenges, the Global Snow Leopard and Ecosystem Protection Program was formed as an alliance among the twelve countries where the species is found. Both statements accurately reflect the primary threats to the species and the international collaborative response.

Q385. The primary legal difference between a National Park and a Wildlife Sanctuary in India is:
Explanation
Both National Parks and Wildlife Sanctuaries are protected areas under the Wildlife Protection Act. The primary legal difference lies in the degree of restriction. In a Wildlife Sanctuary, certain human activities and rights, such as livestock grazing or collection of minor forest produce, may be permitted by the Chief Wildlife Warden. In contrast, such activities are strictly prohibited in National Parks.

Q387. Arrange the zones of a Biosphere Reserve from the outermost area to the innermost protected area: I. Buffer Zone II. Transition Area III. Core Zone Which of the following represents the correct sequence?
Explanation
A Biosphere Reserve is organized into three distinct zones. The outermost area is the Transition Zone, where human settlements and sustainable activities occur. Moving inward, the Buffer Zone surrounds the core and is used for research and education. The innermost part is the Core Zone, which is a strictly protected area dedicated to the conservation of biodiversity with no human interference.

Q390. Identify the incorrect statement regarding the Protected Area Network.
Explanation
In the core zone of a biosphere reserve, human activity is strictly prohibited, while the transition zone allows for active cooperation with local communities.

Such activities can be permitted by the Chief Wildlife Warden if they do not interfere with specific wildlife conservation goals.
