Question

Why aquatic ecosystems have inverted biomass pyramids?

Answer 1

Ecological pyramids:

1. It represents different trophic levels.
2. These are a graphical representation of biomass, productivity, and energy.

Pyramid of biomass:

1. It represents total living biomass or organic matter present at different trophic levels in an ecosystem.
2. The base of the pyramid is always producers.
3. Producers in the aquatic ecosystem are phytoplankton.
4. The second trophic level is small fish.
5. These small fish consume phytoplankton.
6. Large fish consume small fish.
7. The biomass increases as we progress towards a higher trophic level.
8. Thus pyramid of biomass is inverted in the aquatic ecosystem.
