Ecosystem Structure and Function · NCERT Biology

The pyramid of biomass in a sea/ocean ecosystem is generally:

  1. Upright
  2. Inverted
  3. Spindle shaped
  4. Urn shaped
Show answer and explanation

Correct answer: Inverted

In oceans, the pyramid of biomass is inverted because the biomass of fishes (consumers) far exceeds the biomass of phytoplankton (producers). This is possible because phytoplankton have very high turnover rates.
