Which of These Ecosystems Has the Highest Net Primary Productivity

Question

Which of these ecosystems has the highest net primary productivity per square meter?
A) savanna
B) open ocean
C) boreal forest
D) tropical rain forest
E) temperate forest

Accepted Answer

Tropical rain forests have the highest net primary productivity per square meter due to the warm temperature and abundant rainfall, which supports a high biodiversity of plant and animal life. The dense vegetation and high levels of photosynthesis in this ecosystem enable it to produce more organic matter than any other ecosystem, resulting in a high net primary productivity.
