Which of the following best explains why an ecosystem that exhibits very low net primary production [NPP, measured as J/(m2 x year)] could still represent one of the ecosystems that contributes the most to global net primary production?
A) Ecosystems with very low NPP may cover vast areas of the Earth's surface.
B) Ecosystems with very low NPP may have tight recycling of energy.
C) Low NPP ecosystems often store a lot of heat.
D) Higher NPP ecosystems are often located at latitudes where sunlight is less intense.
