Detailed explanation-1: -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-2: -Tropical forests are warm, humid, and found close to the equator. Temperate forests are found at higher latitudes and experience all four seasons.

Detailed explanation-3: -Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Detailed explanation-4: -Tropical rain forest contains varied ecological niches from forest floor to the canopy. Hence tropical rain forests are the most species-rich biome on Earth.

Detailed explanation-5: -The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness).
