Question

Statement A: Tropical rain forests are disappearing fast from developing countries such as India.
Statement B: No value is attached to these forests because these are poor in diversity.
A. Both Statement A and B are correct
B. Statement A is correct but statement B is incorrect
C. Statement A is incorrect but statement B is correct
D. Both statement A and B are incorrect

Answer 1

Hint: Tropical rainforests are dominated by broad-leaved trees that form a dense upper canopy and contain a diverse variety of plants and other life, making up one of the largest biomes on the earth worldwide. Contrary to conventional thinking, in areas with heavy, continuous rainfall, not all tropical rainforests exist.

Complete answer:
The oldest main vegetation type still presents on the Earth is represented by tropical rainforests. However, like all vegetation, the rainforest continues to evolve and change, so modern tropical rainforests are not identical to geological past rainforests. As the world climate cooled down in the middle of the Cenozoic, it also became drier. This is because cooler temperatures contributed, in fact, to a decline in the rate of water evaporation from the surface of the oceans, which in turn led to less cloud formation and less precipitation. The entire hydrological cycle slowed, and tropical rainforests became increasingly confined to equatorial latitudes, dependent on both warmth and reliably high rainfall. Climate zones have formed in regions between the wet tropics and the deserts, in which sufficient rainfall for luxuriant plant growth has been observed for only part of the year. New plant types have developed in these areas from tropical rainforest ancestors to deal with seasonally dry weather, creating tropical deciduous forests. Savannas and tropical grasslands have grown in the drier and more fire-prone areas.
India is home to a variety of truly impressive rainforests that house a large number of species. These rainforests are great places to visit, especially for those with a romantic relationship with nature, wildlife, and greenery. The characteristics of the Western Himalayan rainforests in India are in contrast to those of its eastern forests.

Hence, the correct answer is (C) Statement A is correct but statement B is incorrect.

Note:
These rainforests are very rich in diversity and even endemic to a high degree. They are, thus, of great value. Such forests are disappearing quicker than expected. They need to be conserved. Tropical rainforests are increasingly disappearing from developing nations like India. The explanation is because deforestation, poaching, building, mining, etc. are growing.
