This question tests knowledge about the biogeographic classification of the Earth and India's position within these classifications. Biogeographic realms are large spatial regions of the Earth's land surface, defined by characteristic flora and fauna. Understanding which realms encompass India is key to answering this question.
Correct Option: B) Two
The question asks for the most appropriate reason for the high species diversity in the Himalayan range. We need to evaluate each option based on its ecological relevance to biodiversity.
B) It is a confluence of different bio-geographical zones. The Himalayan range acts as a biological crossroads where species from various biogeographical regions (such as the Palearctic, Indo-Malayan, and Sino-Japanese realms) meet. This unique geographical position, combined with its vast altitudinal gradients and varied climatic conditions, creates a multitude of ecological niches, fostering the evolution and coexistence of a wide array of species, leading to exceptionally high biodiversity.
The question asks to identify the states where the Lion-tailed Macaque is found in its natural habitat. This requires knowledge of the geographical distribution of this specific primate species in India.
A) 1, 2 and 3 only is the correct answer because the Lion-tailed Macaque is endemic to the Western Ghats, and its natural habitat includes the states of Tamil Nadu, Kerala, and Karnataka.
The question asks to identify the biogeographical realm that includes the Himalayan region. This requires knowledge of the major biogeographical realms of the world and their geographical distribution.
Correct Option: B) The Palearctic Realm is the largest biogeographical realm and includes Europe, most of Asia (north of the Himalayas), and North Africa. The Himalayan region, particularly its northern slopes and the Tibetan Plateau, falls within or is strongly influenced by the Palearctic Realm's biogeography. The Himalayas often form a significant boundary between the Palearctic and Indomalayan realms, but the broader region is associated with the Palearctic.
The question asks to identify plants naturally found in the Himalayan region. This requires knowledge of the typical flora associated with mountainous, temperate, and sub-alpine environments.
A) 1 and 2 only is the correct answer because both Oak and Rhododendron are characteristic plant species of the Himalayan ecosystem.
The question asks to identify which of the given options is NOT a biome found in India. To answer this, we need to recall the major biomes present in India based on its diverse geography and climate.
Correct Option: B) Tundra
