A - The figure below shows how net primary productivity (NPP) varies along a rainfall gradient. Describe the patterns seen in this graph, and explain why these occur. B - Where on the planet is NPP the highest for terrestrial ecosystems? For ocean ecosystems? Explain why for each.

However, I can still give you a general idea of how NPP varies along a rainfall gradient. Net Primary Productivity (NPP) is the rate at which plants convert sunlight into chemical energy through photosynthesis, minus the energy used for respiration. In general, Show more…

Give an example of an environmental factor that commonly limits net primary productivity (NPP) in terrestrial ecosystems, and describe why and how this factor limits NPP.

How does NPP vary and what limits NPP? Total NPP for the planet is about 105 x 10^9 metric tons or 105 x 10^15 grams of C per year: About 54% is on land and about 46% is in the sea. Explain latitudinal variation in NPP on land and in the sea. How can the oceans represent ~1/2 of global NPP when the NPP of the open ocean is so low?
