What are the important climatic factors besides water availability and length of day that control net primary productivity?

Question

Quizplus · Accepted Answer

Air and soil temperatures play an important role in controlling net primary productivity. Plants have a range of temperatures at which they can photosynthesize and grow efficiently, and variation outside this range can limit productivity. Soil temperature affects nutrient availability and therefore plant growth.

Answer: D 
 Proximity to the sub-tropical high pressure belt has a significant impact on net primary productivity. Areas located near this pressure belt typically have limited precipitation and experience high temperatures, which can limit plant growth and productivity.

Answer: E 
 Oceanic currents influence productivity by affecting nutrient availability and water temperature. Upwelling of nutrient-rich waters can increase productivity in coastal areas, while changes in currents can impact the distribution of species that contribute to primary productivity.

Note: B and C are not correct choices as photosynthesis and the carbon cycle are processes related to net primary productivity rather than factors that control it.
