Question

choose the correct answer. which organism directly eats submerged aquatic vegetation (sav) in this food web? herbivorous duck osprey bivalves

Explanation:

By observing the food - web diagram, we can see the arrows indicating the flow of energy from one organism to another. The arrow from Submerged Aquatic Vegetation (SAV) points to the Herbivorous Duck, meaning the Herbivorous Duck directly eats SAV. The Osprey is a Quaternary Consumer and preys on other animals, not SAV. Bivalves are Secondary Consumers and do not directly eat SAV.

Answer:

Herbivorous Duck
