Which Biome Has the Greatest Overall NPP

Question

Which biome has the greatest overall NPP?
A) Tropical rain forest
B) Tundra
C) Tropical savanna
D) Temperate forest

Accepted Answer

Tropical rain forests have the greatest overall Net Primary Productivity (NPP) due to their warm and wet climate, which allows for year-round photosynthesis and growth of vegetation. They also have a diverse range of species and nutrient-rich soils that contribute to their high productivity. Tundra has low productivity due to its cold climate and short growing season, while tropical savannas and temperate forests have moderate NPP.
