Inverted Biomass Pyramid in Aquatic — NEET
✅ Asked in NEET 2026The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds that of phytoplankton. Isn't that a paradox? How would you explain this?
NTA tests whether students understand why the biomass pyramid in aquatic ecosystems can be inverted despite being upright on land. The key is that phytoplankton have a much shorter lifespan and faster reproduction rate than fishes—so a smaller standing biomass of phytoplankton can support a larger biomass of fishes over time. Students mistakenly think biomass must follow the same pattern everywhere, forgetting that turnover rate matters. Remember: an inverted pyramid is possible when lower trophic levels have rapid turnover and reproduction, allowing them to continuously replenish despite lower standing biomass at any given moment. This concept directly challenges the typical food chain assumption.
