Question: The land of maximum biodiversity is
(1) Tropical 
(2) Temperate
(3) Monsoonal 
(4) Equatorial

Answer: (1) Tropical 
A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. Tropical rainforests are unique in the high levels of biodiversity they exhibit. Around 40% to 75% of all biotic species are indigenous to the rainforests. Rainforests are home to half of all the living animal and plant species on the planet. Two thirds of all flowering plants can be found in rainforests. A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. Tropical rainforests have been called the “jewels of the Earth” and the “world’s largest pharmacy”, because over one quarter of natural medicines have been discovered within them.
