Natural vegetation MCQ - Practice Questions with Answers

Sundari is a characteristic mangrove tree, especially associated with the Sundarbans, and mangroves grow in tidal, saline, coastal and deltaic conditions. Semi-desert forests occur in dry regions and do not support typical mangrove vegetation. Tropical evergreen forests are dense, high-rainfall forests of humid regions, but they are not defined by tidal water. Monsoon forests are seasonal deciduous forests. Because the question names Sundari and mangrove trees, the correct forest type is tidal forests.

Rosewood, Mahogany, and Ebony are typical valuable hardwood species associated with tropical evergreen forests, especially in warm and very wet regions. Such forests have dense, multilayered vegetation and remain green through the year. Tropical thorn forests are dry-zone forests with species such as acacia and cactus-like shrubs, not these moist-evergreen hardwoods. Montane forests are altitude-based hill forests with a different species mix. Littoral and swamp forests occur near coasts, deltas, and tidal areas and are marked by mangrove or swamp vegetation.

Moist deciduous forests grow where rainfall is fairly high but there is a short dry season. The Himalayan foothills, the northeastern states and the eastern slopes of the Western Ghats fit this broad distribution because they receive substantial monsoonal rainfall. The peninsular plateau, especially its interior parts, is generally drier and is more closely associated in school geography with dry deciduous and thorn-type vegetation. Therefore, among the given regions, the peninsular plateau is treated as the region where moist deciduous forests are not found.

The western slopes of the Western Ghats receive heavy rainfall from the south-west monsoon, so tropical evergreen forests occur there. These forests remain green through the year and have dense, multi-layered vegetation. Alpine forests belong to high mountain regions such as the Himalayas. Savanna is a grassland-with-scattered-trees formation, not the humid windward Ghats. Monsoon forests are deciduous and occur where rainfall is seasonal and comparatively lower than in the wet western slopes.
