There are many ways in which energy can flow through an aquatic ecosystem. One way is as follows:

phytoplankton zooplankton shrimp moray eel shark

This flow of energy can also be represented by a biomass pyramid.

How is each trophic level of the biomass pyramid related to the adjacent trophic levels?
A.
As the trophic levels progress from phytoplankton to sharks, there is a decrease in the amount of biomass but an increase in the amount of available energy.
B.
Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
C.
Each trophic level contains ten times as much biomass as the level below it and one-tenth as much biomass as the level above it.
D.
As the trophic levels progress from phytoplankton to sharks, there is an increase in both the number of individual organisms and the biomass.

C. Each trophic level contains ten times as much biomass as the level below it and one-tenth as much biomass as the level above it.
