True or False - Rapid decay of plants and animals occurs with the help of decomposing rain that breaks down dead organisms.
False Pg 146 Tropical Rainforests help regulate world climate and play vital roles in the nitrogen, oxygen, and carbon cycles.
2x 500 pts Which biome is the most diverse and why?
The tropical rain forest is the biome with the greatest amount of species diversity. Because of the amount of rain and high temperature, there is a large diversity of vegetation. This has led to the evolution of a diverse community of animals.
