Question

chesapeake bay waterbird food web
tertiary consumers: osprey, bald eagle
secondary consumers: gulls and terns, wading birds, large piscivorous fish, sea ducks, tundra swan
primary consumers: small planktivorous fish, bivalves, benthic invertebrates, herbivorous ducks, geese and mute swans
herbivores: zooplankton
primary producers: phytoplankton, submerged aquatic vegetation (sav), vegetation
choose the correct answer.
which producer in this food web has the most predators?

Explanation:

Examine the food - web diagram. Count the number of arrows pointing from producers to their predators. Phytoplankton is consumed by zooplankton and small planktivorous fish. Submerged aquatic vegetation is consumed by benthic invertebrates and herbivorous ducks. Tundra swan is a consumer, not a producer. Phytoplankton has 2 types of predators, while submerged aquatic vegetation has 2 types of predators too. But considering the commonness and the web structure, phytoplankton is more likely to be a base - level food source with more potential predators in a broader ecological sense.

Answer:

phytoplankton
