Question

if the organisms in this food web were arranged in a biomass pyramid, which organisms would have the greatest amount of biomass? select one answer.
coral
parrotfish
phytoplankton
zooplankton
shark
unicornfish

Explanation:

In a biomass pyramid, producers (autotrophs) have the greatest biomass. Phytoplankton are primary producers in this food web, converting sunlight into energy via photosynthesis. Other organisms (coral - which has a symbiotic relationship with algae but is not a major primary producer here, parrotfish, zooplankton, shark, unicornfish) are consumers (primary, secondary, or tertiary), and biomass decreases as we move up trophic levels.

Answer:

Phytoplankton
