Detailed explanation-1: -Over 3 million species live in the rainforest, and over 2, 500 tree species (or one-third of all tropical trees that exist on earth) help to create and sustain this vibrant ecosystem.

Detailed explanation-2: -More than half of the world’s estimated 10 million species of plants, animals and insects live in the tropical rainforests. One hectare (2.47 acres) may contain over 750 types of trees and 1500 species of higher plants. At least 3000 fruits are found in the Rainforests; of these only 200 are now in use.

Detailed explanation-3: -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.

Detailed explanation-4: -The canopy: A tree top power station An estimated 50-90% of life in the rainforest lives up in the trees-swinging, squawking and slithering through the branches. The canopy is the main site of interchange for energy, water vapor and atmospheric gasses like oxygen and carbon dioxide.

Detailed explanation-5: -The Amazon Rainforest is known to be home to 427 mammal species, 1, 300 bird species, 378 species of reptiles, and more than 400 species of amphibians. Species are still being discovered every year. Over 10, 000 species of beetles have been discovered in this area over the last decade.
