Final answer:
Brazil has the highest net primary productivity due to its warm and wet climate that optimizes photosynthesis and plant growth.
Step-by-step explanation:
The location with the highest net primary productivity would be Brazil. Net primary productivity is the rate at which photosynthetic primary producers incorporate energy from the sun. It is influenced by factors such as sunlight, temperature, and precipitation. Brazil, being a tropical country with a warm and wet climate, provides optimal conditions for photosynthesis and plant growth, resulting in high net primary productivity.
