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 an omnivore? select all that apply. the arrow between the salps and the silverfish the arrow between the microzooplankton and the salps the arrow between the microzooplankton and the copepod

Explanation:

Step1: Identify primary consumers

Primary consumers eat producers. In this food - web, microzooplankton eat diatoms (producers), salps eat ice algae (producers), so microzooplankton and salps are primary consumers.

Step2: Identify omnivores

Omnivores eat both plants and animals. Copepod and silverfish can consume different types of organisms including plants and animals, so they are omnivores.

Step3: Check energy - transfer arrows

We need to find arrows from primary consumers (microzooplankton, salps) to omnivores (copepod, silverfish). The arrow from microzooplankton to salps is not correct as salps is also a primary consumer. The arrow from salps to silverfish, microzooplankton to salps, and microzooplankton to copepod show energy moving from a primary consumer to an omnivore.

Answer:

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