Given below is an imaginary pyramid of biomass. Which of these organisms, possibly constitute the different trophic levels?
The inverted shape of the pyramid typically refers to the pyramid of biomass in an aquatic ecosystem specifically in the oceans where the primary produces (PP) are the phytoplanktons and primary consumers (PC) are the small fishes feeding on them. In oceans, a food chain typically starts with phytoplankton and ends at predatory fish. In terms of the biomass of these organisms phytoplanktons have the least biomass measure when compared to the organisms in the higher trophic levels.
