Question

Which of the following explains the inversion of the aquatic pyramid of biomass?

Answer 1

Answer;

A. high phytoplankton turnover rate

Explanation;

-Pyramid of biomass  is a diagrammatic representation of the amount of organic material, measured in grams of dry mass per square meter (g m–2), found in a particular habitat at ascending trophic levels of a food chain.

The pyramid of a biomass in ocean inverted because:

• Food chain in ocean - {Phytoplankton → zooplankton → predatory fish.}
• The biomass of zooplankton is greater than phytoplankton (the producer ) because of their small size and low weight . The predatory fish is much larger than zooplankton .
• The producer in ocean or aquatic ecosystem producers are phytoplankton have short life span and turn over and have lower mass than zooplankton .
• The biomass of tropic level depends on the longevity of member
