this food web is from an ocean ecosystem in the ross sea, off the coast of antarctica. which arrows show energy moving from a secondary consumer to tertiary consumer? select all that apply. the arrow between the krill and the icefish the arrow between the silverfish and the icefish the arrow between the salps and the silverfish

Explanation:

Step1: Define consumer levels

Primary consumers eat producers, secondary consumers eat primary - consumers, and tertiary consumers eat secondary consumers.

Step2: Analyze each option

• Krill is a primary consumer (eats phytoplankton), so the arrow between krill and icefish is not from secondary - to tertiary - consumer.
• Silverfish is a secondary consumer, and icefish is a tertiary consumer. The arrow between silverfish and icefish shows energy moving from secondary to tertiary consumer.
• Salps are primary consumers, so the arrow between salps and silverfish is not from secondary - to tertiary - consumer.

Answer:

The arrow between the silverfish and the icefish
