Why might aquatic ecosystems have inverted biomass pyramids?

Answer 1
  • 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..........

Answer 2

Aquatic ecosystems may have inverted biomass pyramids due to factors such as rapid growth rates of phytoplankton, which form the base of the food chain, high turnover rates of zooplankton populations, and the presence of large biomass-consuming organisms at the top of the food chain, such as filter-feeding fish or whales. Additionally, energy transfer efficiency can be higher in aquatic ecosystems compared to terrestrial ones, allowing for a larger biomass of higher trophic level organisms despite a smaller biomass of primary producers.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
