Correct Answer:
Option A - The pyramid of biomass represents the amount of living or recently dead biological material present at different trophic levels in an ecosystem. In a typical ecosystem, producers, such as plants or phytoplankton, occupy the base of the pyramid and have the highest biomass. This is because they are the largest group and are responsible for producing energy through photosynthesis, which supports all other trophic levels.
