Title: Re: what world ecosystem have high and low net productivity? Why? Post by: bio_man on Nov 2, 2014 The world's ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests.

In doing that, we find that now the most productive systems are open oceans, tropical rain forests, savannas, and tropical seasonal forests.
