Answer» Answer is : (d) Tropical evergreen forests Diversity of species is highest in the tropical evergreen forests primarily because there are fewer ecological obstacles for biodiversity. Like the climate is wet and warm, plants and animals have the greatest access to consistent energy, water and carbon, etc. This reduces the selection for traits that emphasise the ability to withstand environmental stresses such as cold and drought, etc., and promotes higher rates of speciation. |
