Final answer:
Primary productivity is the biomass produced by primary producers and is highest in warm and wet climates. The correct order from greatest to smallest primary productivity among the given biomes is: Tropical Rainforest, Temperate Forest, Taiga, and Tundra.
Step-by-step explanation:
The amount of biomass produced yearly by primary producers in an area is known as primary productivity. To rank biomes from greatest to smallest primary productivity, we consider temperature, moisture, and the environmental conditions that support photosynthesis and plant growth.
Warm and wet climates are most conducive for high primary productivity because they support high photosynthetic rates. Therefore, tropical rainforests with warm temperatures, abundant water, and a year-round growing season have the highest primary productivity. Following on the list are temperate forests, which experience moderate temperatures and sufficient rainfall. Then we have the taiga (or boreal forests), which have lower temperatures and less biodiversity than temperate forests. Lastly, the tundra biome, with its cold climate and short growing season, has the least primary productivity.
By considering these factors, the correct order from greatest to smallest primary productivity among the given biomes is: Tropical Rainforest -> Temperate Forest -> Taiga -> Tundra.
