Final answer:
The tropical wet forests biome has the highest energy budget and greatest species diversity due to its high net primary productivity and ideal conditions for plant growth. These forests support a wide variety of plant, fungi, animal, and other organism species.
Step-by-step explanation:
The tropical wet forests biome has the highest energy budget and the greatest species diversity. These forests have high net primary productivity due to ideal annual temperatures and precipitation that promote plant growth. As a result, the extensive biomass in these forests supports a wide variety of plant, fungi, animal, and other organism species. On average, between 100 and 300 species of trees can be found in a single hectare of South American tropical wet forests.
