Natural Vegetation and Habitats

Yes, rain forests are present near the equator.

In the Eastern Himalayas, the altitudinal zone between 1000 and 2000 meters is typically occupied by sub-tropical broad-leaved forests. Below this zone are tropical evergreen forests, and above it are temperate forests.

In equatorial climates, high rainfall and rapid decomposition mean nutrients are concentrated in the topsoil. Trees develop shallow roots to quickly absorb these nutrients and because water is readily available near the surface.

Desert plants, or xerophytes, often have pointed leaves or spines to reduce the surface area for transpiration. This adaptation helps the plant conserve water in arid environments.

The Pampas are vast, fertile plains located in South America, primarily in Argentina, Uruguay, and southern Brazil. They are classified as temperate grasslands and are known for their agriculture and cattle ranching. Other terms like Steppes or Savannas refer to grasslands in different regions or climates.

The term veld (or veldt) refers to the wide-open rural spaces of South Africa, specifically the high plateau grasslands. Other terms like prairies and pampas refer to similar biomes in North and South America respectively.

Biomes are large ecological areas on the earth's surface, with fauna and flora adapting to their environment. They are primarily identified by the types of vegetation (plants) present.

In geography, temperate or tepid latitudes of the globe lie between the tropics and the polar regions. In a very broad sense, temperate climate also includes a subtropical climate, variants: subtropical semi-desert/desert, humid subtropical, oceanic subtropical and Mediterranean climate. However, a typical temperate climate is one of the four climate zones in the world, besides polar regions (subarctic climate, arctic climate, tundra climate, ice cap climate) and the sub-tropics, tropics. The forest types found in cool temperate regions are: Deciduous forests, Evergreen coniferous forests and Mixed forests.

The descending order of altitude for Himalayan vegetation is: Alpine vegetation (highest), Coniferous forests, Evergreen forests, and Tropical forests (lowest). Therefore, the sequence is 2-1-4-3.

Statement 1 is correct: One of the principal deciding factors of the type of natural vegetation of a region is the rainfall of that region. This factor becomes more crucial in the case of tropical monsoon lands. Statement 2 is also correct: Monsoons lands are characterised by marked dry period. In such dry periods, trees shed their leaves. Hence, monsoon lands are covered with deciduous trees.

This is the correct answer. Tropical deciduous forests are the most widespread in India. They are also called the monsoon forests. They spread over regions which receive rainfall between 70-200 cm.

Semi evergreen forests have a mixture of evergreen and moist deciduous trees. Main species are white cedar, hollock and kail. Thus, this is the correct answer.

This is the correct answer as both statements are correct.
