Question

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

Explanation:

1. First, identify primary consumers and omnivores. Primary consumers eat producers, and omnivores eat both plants and animals. In this food - web, microzooplankton, salps, and copepods are primary consumers. Krill is a primary consumer, and icefish is an omnivore.
2. Analyze each option:

• The arrow between microzooplankton and krill: Krill is a primary consumer, not an omnivore, so this is incorrect.
• The arrow between salps (primary consumer) and icefish (omnivore) shows matter moving from a primary consumer to an omnivore.
• The arrow between copepod (primary consumer) and salps (primary consumer), not from a primary consumer to an omnivore.

Answer:

the arrow between the salps and the icefish
