Question

which arrows show energy moving from a producer to an omnivore? select all that apply.
the arrow between the diatom and the krill
the arrow between the diatom and the copepod
the arrow between the ice algae and the salps

Explanation:

1. Producers: Diatoms and ice algae are producers (autotrophs that make their own energy).
2. Omnivores: Krill are omnivores (they eat both producers like diatoms and other consumers); salps are also omnivores (they consume producers like ice algae and organic matter). Copepods are typically herbivores (eat only producers like diatoms).
3. Match the energy flow:

• Diatom (producer) → Krill (omnivore): Valid flow.
• Diatom (producer) → Copepod (herbivore): Invalid, copepod is not omnivore.
• Ice algae (producer) → Salps (omnivore): Valid flow.

Answer:

• the arrow between the diatom and the krill
• the arrow between the ice algae and the salps
