The inversion of terrestrial and aquatic energy pyramids is dependent upon the nature of that environment’s particular _______.

Energy pyramids are not inverted, but biomass pyramids can be. In aquatic environments, tiny producers such as phytoplankton reproduce and are consumed quickly, so their standing biomass may be lower than that of the primary consumers they support. This difference depends on the nature of the producers, so the correct choice is “producers.”
