Rainforests
A new study discovers that the Meghalayan rain forest, the northernmost in the world, is similar in structure and diversity to the other rain forests found near the Equator. Consider the following given statements about rain forests:
- Rain forests are found between ten degrees North and South latitudes from the Equator.
- Owing to tremendous amount and diversity of foliage in tropical rain forests, rain forest soils are rich in nutrients.

Explanation :
- Tropical forests are closed canopy forests growing within 10 degrees north or south of the equator.
- These are very wet places, receiving more than 200 cm rainfall per year, either seasonally or throughout the year.
- Temperatures are uniformly high - between 20°C and 35°C.
- The majority of tropical rainforests are found in four biogeographic realms: the Afrotropical(mainland Africa, Madagascar, and scattered islands), the Australian (Australia, New Guinea, and the Pacific Islands), the Indomalayan(India, Sri Lanka, mainland Asia, and Southeast Asia), and the Neotropical(South America, Central America, and the Caribbean islands).The heavy rains that occur in rainforests wash organic material from the soil, a process known as leaching, rendering the soil nutrient-less.
- A common feature of many tropical rainforests is the distinct buttress roots of trees. Instead of penetrating to deeper soil layers, buttress roots create a widespread root network at the surface for more efficient uptake of nutrients in a very nutrient poor and competitive environment.
- Rainforests are the most productive and most complex ecosystems on Earth.
