Why might aquatic ecosystems have inverted biomass pyramids?
- See below:
- In aquatic ecosystem, the pyramid of biomass may be inverted.
- EXAMPLE : Biomass of zooplanktons is higher than that of phytoplanktons as the life span of former is longer and latter multiply much faster though having shorter lifespan.
A number of generations of phytoplanktons may thus be consumed by single generation of zooplanktons .
Biomass of fish may be larger as fishes are large in size with longer lifespan and a number of generations of zooplanktons can be consumed by fishes.
However, during transfer, only 10 % of the biomass of one generation is passed on to next trophic level .
Sum total of biomass of benthic animals and brown algae exceeds the other producers and consumers in aquatic ecosystem.
Hope this will help u..........
