which biome has the species richness
Tropical rain forests occur in regions near the equator. The climate is always warm (between 20Â° and 25Â° C) with plenty of rainfall (at least 190 cm/year). The rain forest is probably the richest biome, both in diversity and in total biomass.The tropical rain forest has a complex structure, with many levels of life.ropical rain forests occur in regions near the equator.
