ecological pyramid

Question

An inverted biomass pyramid is characteristic of which ecosystem component?

RankGuru · Accepted Answer

1. **Pyramid of Biomass**: Represents the total dry weight of living matter at each trophic level.
2. **Upright Pyramids**: In most terrestrial ecosystems ($e.g.,$ forests, grasslands), the producer biomass is far greater than the herbivore and carnivore biomass.
3. **Inverted Pyramids**: Typical of **aquatic ecosystems** (like pond or sea).
4. **Explanation**: The primary producers (Phytoplankton) have a very small biomass at any given time because they are tiny and eaten very rapidly. However, they have a very high turnover rate (rate of production), which supports a larger biomass of Zooplankton and fish.
