Question

which one of the following organisms is eaten by an omnivore in this food web?
golden algae
copepod
whirligig beetle
water cricket

Explanation:

1. First, identify omnivores in the food web: The shiner eats both bacteria (a decomposer) and water fleas (an animal), so it is an omnivore. The water flea eats copepods (animal) and rotifers (animal), plus green algae (producer), so it is also an omnivore.
2. Analyze each option:

• Golden algae: Eaten by backswimmer (carnivore) and copepod (herbivore/omnivore? It only eats golden algae here, so herbivore).
• Copepod: Eaten by water flea (omnivore, as it eats both plant and animal matter).
• Whirligig beetle: Eaten by black crappie (carnivore).
• Water cricket: Eaten by black crappie (carnivore).

1. The copepod is the organism eaten by an omnivore (water flea) in this web.

Answer:

copepod
