Detailed explanation-1: -Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Detailed explanation-2: -Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. The Amazon rainforest is the world’s largest tropical rainforest. It is home to around 40, 000 plant species, nearly 1, 300 bird species, 3, 000 types of fish, 427 species of mammals, and 2.5 million different insects.

Detailed explanation-3: -Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate. Tropical rainforests have warm temperatures and lots of precipitation. The high intensity sunlight provides energy for producers in the rainforest and supports a wide variety of plant growth.

Detailed explanation-4: -Scientists estimate that 60-90 percent of life in the rainforest is found in the trees, with the canopy holding the most biodiversity of species. The emergent layer is the tallest layer of the rainforest.
