Question

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

Explanation:

Step1: Identify primary and secondary consumers

Primary consumers eat producers, secondary consumers eat primary - consumers. In the food - web, we need to find arrows from primary to secondary consumers.

Step2: Analyze each option

• For the arrow between salps and icefish: Salps are primary consumers (eat microzooplankton etc.), icefish are secondary consumers (eat salps etc.), so this arrow shows energy moving from primary to secondary consumer.
• For the arrow between microzooplankton and salps: Microzooplankton are not primary consumers in the context of this question as they are being eaten by salps which are primary consumers. This arrow shows energy moving from a lower - level organism to a primary consumer, not from a primary to a secondary consumer.
• For the arrow between copepod and silverfish: Copepods are primary consumers (eat diatoms etc.), silverfish are secondary consumers (eat copepods etc.), so this arrow shows energy moving from primary to secondary consumer.

Answer:

the arrow between the salps and the icefish, the arrow between the copepod and the silverfish
