Question

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

a. high phytoplankton turnover rate
b. slow aquatic predator metabolisms
c. small number of aquatic consumers
d. high energy content of phytoplankton

Answer 1

Answer;

A. high phytoplankton turnover rate

Step-by-step 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

Answer 2

its A. i just took the test :)
