False.

Per unit area most terrestrial ecosystems (e.g., tropical rainforests) have higher net primary productivity than the open ocean. Aquatic primary production (especially in the open ocean) is often light- and nutrient-limited and has low standing biomass even though phytoplankton can have rapid turnover. Productive aquatic habitats (estuaries, wetlands, upwelling zones, coral reefs) are exceptions.
