Question

Quizplus · Accepted Answer

Open oceans have the smallest average NPP due to nutrient limitations, lakes generally have higher NPP than open oceans but lower than more productive ecosystems. Savannahs have moderate NPP, estuaries have high NPP due to nutrient-rich waters, and tropical rainforests have the highest NPP due to warm temperatures and high rainfall.
