Solution

Tropical rain forests are located in the equatorial regions where the  annual rainfall exceeds $140\, cm$. They are also called jungles and cover one twelveth of earth's surface but contain more than half of the earth's flora and fauna (i.e., rich in biodiversity). Now-a-days these forests are disappearing due to excessive cutting of forests for domestic purposes like fuel, furnitures, accomodations, cloths, resin, gum, etc
