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 producer to a primary consumer? select all that apply.
the arrow between the diatom and the microzooplankton
the arrow between the microzooplankton and the copepod
the arrow between the ice algae and the krill

Explanation:

1. First, identify producers: these are autotrophs (diatom, ice algae) that make their own food. Primary consumers are herbivores that eat producers.
2. - Diatom (producer) → microzooplankton (primary consumer): this is a producer to primary consumer flow.

• Microzooplankton (consumer) → copepod (consumer): this is consumer to consumer, not producer to primary consumer.
• Ice algae (producer) → krill (primary consumer): this is a producer to primary consumer flow.

Answer:

the arrow between the diatom and the microzooplankton
the arrow between the ice algae and the krill
