In most terrestrial ecosystems (grasslands, forests, and deserts), the biomass pyramid is upright, meaning producers (plants) have the highest biomass, followed by primary consumers, secondary consumers, and so on. However, in an oceanic ecosystem, the biomass pyramid is inverted because: Producers (phytoplankton) have a very low biomass but a high turnover rate (they reproduce and grow rapidly). Primary consumers (zooplankton, small fish, etc.) have a greater biomass than phytoplankton because they consume producers faster than producers can accumulate biomass.
