Solution
The correct option is C Tropical rain forests
Tropical rain forests occur over equatorial or sub-equatorial regions, with abundant warmth and rainfall (200-350 cms/year) almost throughout the year. The forests are impenetrable with maximum diversity. Productivity is also maximum. Standing crop biomass is highest. A lot of nutrients remains locked in vegetation. These forests occur in Congo basin of Africa and Amazon basin in South America. It is estimated that these forests contain 200 different types of trees in one hectare, 70 to 80 percent of all insects and 80 to 85 percent of all birds. Epiphytes, Mosses, Ferns and Orchids are abundant.
